8510C performance verification program?
I just received a paper manual for the 8510C system and on site service referring to version A.03.01 of the 8510C performance verification program.Keysight.com says, "The latest revision is A.05.01. "
What are the known sources for this?

10390A System Performance Analysis Software for 1650B logic analyzer
Hi all,
I'm looking for a copy of the 10390A System Performance Analysis (SPA)
Software for the 1650B logic analyzer, and it has so far eluded me,
can anyone here help out?
EBay has yielded plenty of manuals, and even a sealed set of disks for
the 16550A version of the software, but nothing for the 1650B.
The SPA software replaces the SYSTEM_ file on the 1650B boot disk and
is a superset of the regular 1650B functionality, so it's possible
that you may have it without knowing it! The telltale sign is the
presence of an additional "SPA" entry below the "Timing" and "State"
machine type options in the system configuration screen.
If any of you have a copy and would be willing to share it (I'm happy
to provide blank media and cover reasonable costs for your time and
postage), I would very much appreciate it!
Thanks,
Richard Halkyard

Re: HP 140 Series Fan Noise
As a last ditch effort, sure, it might help. But an ordinary oil film won't allow wear until the oil disappears. Typically, an oilite bearing will have a piece of oil soaked felt touching the bearing to act as a reservoir. -Chuck Harris On Mon, 8 Apr 2024 13:09:49 -0400 "Roy J.

Re: HP 140 Series Fan Noise
I would look for a label, or perhaps a bit of steel, that is interacting with the magnetic barrel that is pressed inside of the fan's hub. Non ball bearings can't make noises like that. What I think you have is something that is the equivalent of using a clothes pin to attach a playing card to your bicycle so it made a noise against the spokes. -Chuck Harris On Mon, 8 Apr 2024 12:40:30 -0400 (EDT) "n4buq" <n4buq@...> wrote: I tested it on the bench before installing it in the 140B and it

Hmmm?
That could be mechanical interference, where some piece of
insulation, inside of the motor, is brushing against something
that is moving, such as the rotating magnetic field.
Or, it could be windage noise from the fan blades being too
close to an immovable object... such as a chassis piece, or a
heatsink.
Does the motor make noise when it is run outside of its mounts?

When an oilite bearing fails, it forces the shaft to
move in and out... basically, dipping its toes into
the unworn shaft area.
The noise it makes sounds like "brum brum brum..."
The next phase is when the bearing gap becomes too wide
to work without the shaft bouncing between contacts with
the oilite.
The noise this makes is a squegging sound. While the
bounce is happening, the shaft is stealing significant
power, so often the squegg stops when a certain speed is
hit.
During the squegging phase, metal is often rolled up out
of the bronze and the shaft will try out seizing. Lots
of high pitched squealing happens before the shaft freezes.
The only of these phases that can be saved with lubrication,
long term, is the brum brum brum phase...

When I had the bushing pulled from the shaft, cleaned the ID of
the bushing with IPA and a cotton swab. I noted that there was
just a bit of something black that came off on the swab and I
presume that was either carbon from the bushing or from the
shaft itself. If bushing wear is an issue and an exact
replacement bushing isn't available, then I'm just going to
leave it alone as I don't have a machine shop handy.
While it might have run low on lubricant at some point in the
last ~54 years (the main transformer has July 09, 1970 stamped
on it), it did have a decent amount of oil on the shaft and
bushing when I disassembled it.
I take it that some motors in the 140-series that, perhaps, have
been maintained properly are not this noisy?

Hi Jim,
Like it or not, oilite (aka sintered bronze) is more than just
the bronze that forms its structure.
Oilite, is made through a process called sintering. What is
done is bronze particles and carbon particles are mixed
together with a glue (binder) to form a thick paste, which is
then packed into a bearing shaped mold and dried.
The resulting bearing shaped object is put into a kiln and
heated in an inert atmosphere until the bronze particles just
melt forming a foam like structure filled with carbon and
binder. The kiln is then cooled to below melting, and air is
introduced, causing the hot carbon, and binder to burn away...
without remelting the bronze.
Left behind are remnants of the carbon binder which are in the
form of carbides and other hard, abrasive, substances.... Oh
well!
When the oilite bronze foam is filled with oil, the oil wicks
out and forms a meniscus of oil between the shaft and the
oilite, on which the shaft floats... never making contact
with the oilite.
Steel floating on a meniscus of oil is the foundation on which
most lubrication works...
When the oil invariably evaporates, the shaft stops floating,
and is let down to run on the bronze. When this happens, the
shaft is running against the oilite bronze matrix, and comes
into contact with the hard abrasive materials that were left
behind when the oilite bronze matrix was made.
Most folks know that some forms of carbon, notably diamond are
very abrasive substances. What most don't know is all forms
of carbon are abrasive.
What about graphite, you say?
Graphite is slippery because it is composed of sheets of
carbon where the atoms in the sheet are strongly bonded, but
the bonds between the sheets are very weak. This allows the
sheets to stay as sheets, but layers of sheets to slide
loosely against each other... kind of like they had ball
bearings between them.
Graphite is useful as a bearing because it sticks strongly to
the bearing metals (shaft, etc...), protecting them, but only
loosely to itself.
More than anyone wanted to know about bearings...

[HP-Agilent-Keysight-equipment] HP 140 Series Fan Noise What
typically happens to bronze sleeve bearings istwo things:1)
the oil that impregnates the bronze foam runs short,?? and no

without oil is abrasive, and wears away?? the steel shaft
until it is small enough that it cannot?? be fully supported
on a film of oil.? This allows the shaft to rattle around in
the bronze hole, making noise and doing more damage.When you
oil up such a mess, the oil will not soak into thebronze
"sponge", because the friction smears the bronze untilall of
the pores in its hole are closed.? The oil in the now too
large gap just gets slung away until it is onceagain dry and
making noise.A new bronze/oilite bearing can be substituted,
but you willprobably find that one that is undersized enough

to fitover the un worn shaft.? The solution is to reduce the
shaftsize just enough to fit through the new
bearing...-Chuck HarrisOn Sun, 7 Apr 2024 13:59:11 -0400

I finally got the standard oscillator removed from the 5350B, recently I had trouble getting it out because it appeared to be seized on.
How I got the oscillator off was by carefully individually heating 3 pins on the board holding the oscillator in place, slowly sliding the pins out of the main board until the oscillator started to come out. Before the oscillator came out I found glue like material securing the oscillator to the board which I cut through and out it came out . There were two glue like strips on each side of the oscillator and main board, looks like double sided tape but very strong.
I confirmed the oscillator actually slides in by pins to pin sockets the main board, I heated up each pin socket and slide them down where they originally went.
In my opinion removing the oscillator was very difficult and made me nervous. I could not spray penetrating oil under the oscillator because the gap was so small and fear of leaving oil residue if it still wouldn't come out.
After letting the oven heat up for a while with the instrument off I turned it on noticing on the A5 board Phase unlocked red light came on. Applying a signal to the input from the 8642B and 3325B I noticed the frequency read out was way off on both 5350B inputs. I flipped the power switch off then back on again and noticed the same thing but then the Phase unlocked red light eventually went out and the frequency read out on both inputs were reasonably close what I recall but not exact. Not sure what was going on there but every time I power on the Phase unlocked briefly flashes then goes out or oddly when I push Auto on the front panel phase unlock comes on and seems to flicker but goes away when I push manual.
Adjustment of the 60111 oscillator to match the 5350 to the 3325B oscillator time base, readouts were perfect as the 5350 tracked perfectly to whatever frequency the 3325B had. I ran the diagnostics 1 self test on the 5350 and got a pass.

Re: HP 8757C SWP DAC Fail
Thanks Hb9ica but the table you sent me refers to the main Error as in the first picture.
the second step is "INSTRUMENT VERIFY" and the result is " DAC BIT CHECK",
the third step is "ADC TEST - DAC BIT CHECK" and the result is " SWP DAC Fail 0000 00000 0010 "
Where can I look for this address?
Thanks for any suggestions.

Re: Looking for 10K Potentiometer for HP 1404A Vertical Amplifier (HP P/N 2100-2828)
I happened to have an OHMITE 10k pot in my spare parts drawer and, from the outside, the resistive element looked the same. I disassembled it and, sure enough, it is the same as the one I broke so I can swap that part in and that should restore the old pot to working like it should.
Thanks,

Anyone know where I might source a replacement for the POSITION controls in a
1404A? If I can't find the exact replacement, I could take the guts out of the
same series pot. The POSITION control for each channel has a hollow shaft
where the switch that enables the display and INVERT function to pass through
to the switch behind the pot. If the exact pot isn't available, then the guts
from a a Centralab pot like that one but, perhaps, without the hollow shaft
could be swapped.
Full disclosure: I had disassembled this pot, cleaned it, and reassembled it but
in the process, in an attempt to get the housing to be installed tightly enough
so that it didn't rattle, I squeezed the small fingers too hard and cracked the
phenolic on which the carbon track was placed so it is completely unusable.
One of the other POSITION controls is also misbehaving and, if I rotate it fully
CCW, it shorts to ground. I plan to attempt to repair that one but will be
very careful not to break this one too. I've repaired several pots like this
and never broke one but those mostly had a plastic or fiber support for the
carbon track. Of course the phenolic (or, maybe, bakelite?) is brittle and
cracked without all that much pressure.
Thanks in advance for any help with this,

Re: HP 140 Series Fan Noise
I tested it on the bench before installing it in the 140B and it still made the same noise. I tried different orientations and that didn't seem to make much, if any, difference.
Thanks,

Hmmm?
That could be mechanical interference, where some piece of
insulation, inside of the motor, is brushing against something
that is moving, such as the rotating magnetic field.
Or, it could be windage noise from the fan blades being too
close to an immovable object... such as a chassis piece, or a
heatsink.
Does the motor make noise when it is run outside of its mounts?

When an oilite bearing fails, it forces the shaft to
move in and out... basically, dipping its toes into
the unworn shaft area.
The noise it makes sounds like "brum brum brum..."
The next phase is when the bearing gap becomes too wide
to work without the shaft bouncing between contacts with
the oilite.
The noise this makes is a squegging sound. While the
bounce is happening, the shaft is stealing significant
power, so often the squegg stops when a certain speed is
hit.
During the squegging phase, metal is often rolled up out
of the bronze and the shaft will try out seizing. Lots
of high pitched squealing happens before the shaft freezes.
The only of these phases that can be saved with lubrication,
long term, is the brum brum brum phase...

When I had the bushing pulled from the shaft, cleaned the ID of the

bit of something black that came off on the swab and I presume that
was either carbon from the bushing or from the shaft itself. If
bushing wear is an issue and an exact replacement bushing isn't
available, then I'm just going to leave it alone as I don't have a
machine shop handy.
While it might have run low on lubricant at some point in the last
~54 years (the main transformer has July 09, 1970 stamped on it),
it did have a decent amount of oil on the shaft and bushing when I
disassembled it.
I take it that some motors in the 140-series that, perhaps, have
been maintained properly are not this noisy?

Hi Jim,
Like it or not, oilite (aka sintered bronze) is more than just
the bronze that forms its structure.
Oilite, is made through a process called sintering. What is done
is bronze particles and carbon particles are mixed together with
a glue (binder) to form a thick paste, which is then packed into
a bearing shaped mold and dried.
The resulting bearing shaped object is put into a kiln and
heated in an inert atmosphere until the bronze particles just
melt forming a foam like structure filled with carbon and
binder. The kiln is then cooled to below melting, and air is
introduced, causing the hot carbon, and binder to burn away...
without remelting the bronze.
Left behind are remnants of the carbon binder which are in the
form of carbides and other hard, abrasive, substances.... Oh
well!
When the oilite bronze foam is filled with oil, the oil wicks out
and forms a meniscus of oil between the shaft and the oilite, on
which the shaft floats... never making contact with the oilite.
Steel floating on a meniscus of oil is the foundation on which
most lubrication works...
When the oil invariably evaporates, the shaft stops floating, and
is let down to run on the bronze. When this happens, the shaft
is running against the oilite bronze matrix, and comes into
contact with the hard abrasive materials that were left behind
when the oilite bronze matrix was made.
Most folks know that some forms of carbon, notably diamond are
very abrasive substances. What most don't know is all forms of
carbon are abrasive.
What about graphite, you say?
Graphite is slippery because it is composed of sheets of carbon
where the atoms in the sheet are strongly bonded, but the bonds
between the sheets are very weak. This allows the sheets to stay
as sheets, but layers of sheets to slide loosely against each
other... kind of like they had ball bearings between them.
Graphite is useful as a bearing because it sticks strongly to the
bearing metals (shaft, etc...), protecting them, but only
loosely to itself.
More than anyone wanted to know about bearings...

[HP-Agilent-Keysight-equipment] HP 140 Series Fan Noise What
typically happens to bronze sleeve bearings istwo things:1) the

without oil is abrasive, and wears away?? the steel shaft until
it is small enough that it cannot?? be fully supported on a
film of oil.? This allows the shaft to rattle around in the
bronze hole, making noise and doing more damage.When you oil up
such a mess, the oil will not soak into thebronze "sponge",
because the friction smears the bronze untilall of the pores in
its hole are closed.? The oil in the now too large gap just
gets slung away until it is onceagain dry and making noise.A
new bronze/oilite bearing can be substituted, but you
willprobably find that one that is undersized enough to fit in
the worn section of the shaft, will be too tight to fitover the
un worn shaft.? The solution is to reduce the shaftsize just
enough to fit through the new bearing...-Chuck HarrisOn Sun, 7

Re: Agilent 54622D with broken digital inputs - Fixable?
Depending on where the chip came from, it might have been
left over from a gold harvesting operation.
The modern gold prospectors soak gold plated IC's, etc... in
aquaregia, to remove the gold plating, without removing much
of the base metal (steel).
Typically, the leads will appear to have a purplish cast after
this has been done, and won't solder worth beans.

Re: HP 140 Series Fan Noise
Hmmm? That could be mechanical interference, where some piece of insulation, inside of the motor, is brushing against something that is moving, such as the rotating magnetic field. Or, it could be windage noise from the fan blades being too close to an immovable object... such as a chassis piece, or a heatsink. Does the motor make noise when it is run outside of its mounts? -Chuck Harris On Mon, 8 Apr 2024 10:36:38 -0400 (EDT) "n4buq" <n4buq@...> wrote: Again, no telling what went on with it before I got it; however, I

When an oilite bearing fails, it forces the shaft to
move in and out... basically, dipping its toes into
the unworn shaft area.
The noise it makes sounds like "brum brum brum..."
The next phase is when the bearing gap becomes too wide
to work without the shaft bouncing between contacts with
the oilite.
The noise this makes is a squegging sound. While the
bounce is happening, the shaft is stealing significant
power, so often the squegg stops when a certain speed is
hit.
During the squegging phase, metal is often rolled up out
of the bronze and the shaft will try out seizing. Lots
of high pitched squealing happens before the shaft freezes.
The only of these phases that can be saved with lubrication,
long term, is the brum brum brum phase...

When I had the bushing pulled from the shaft, cleaned the ID of the
bushing with IPA and a cotton swab. I noted that there was just a
bit of something black that came off on the swab and I presume that
was either carbon from the bushing or from the shaft itself. If
bushing wear is an issue and an exact replacement bushing isn't
available, then I'm just going to leave it alone as I don't have a
machine shop handy.
While it might have run low on lubricant at some point in the last
~54 years (the main transformer has July 09, 1970 stamped on it),
it did have a decent amount of oil on the shaft and bushing when I
disassembled it.
I take it that some motors in the 140-series that, perhaps, have
been maintained properly are not this noisy?

Hi Jim,
Like it or not, oilite (aka sintered bronze) is more than just
the bronze that forms its structure.
Oilite, is made through a process called sintering. What is done
is bronze particles and carbon particles are mixed together with
a glue (binder) to form a thick paste, which is then packed into
a bearing shaped mold and dried.
The resulting bearing shaped object is put into a kiln and
heated in an inert atmosphere until the bronze particles just
melt forming a foam like structure filled with carbon and
binder. The kiln is then cooled to below melting, and air is
introduced, causing the hot carbon, and binder to burn away...
without remelting the bronze.
Left behind are remnants of the carbon binder which are in the
form of carbides and other hard, abrasive, substances.... Oh
well!
When the oilite bronze foam is filled with oil, the oil wicks out
and forms a meniscus of oil between the shaft and the oilite, on
which the shaft floats... never making contact with the oilite.
Steel floating on a meniscus of oil is the foundation on which
most lubrication works...
When the oil invariably evaporates, the shaft stops floating, and
is let down to run on the bronze. When this happens, the shaft
is running against the oilite bronze matrix, and comes into
contact with the hard abrasive materials that were left behind
when the oilite bronze matrix was made.
Most folks know that some forms of carbon, notably diamond are
very abrasive substances. What most don't know is all forms of
carbon are abrasive.
What about graphite, you say?
Graphite is slippery because it is composed of sheets of carbon
where the atoms in the sheet are strongly bonded, but the bonds
between the sheets are very weak. This allows the sheets to stay
as sheets, but layers of sheets to slide loosely against each
other... kind of like they had ball bearings between them.
Graphite is useful as a bearing because it sticks strongly to the
bearing metals (shaft, etc...), protecting them, but only
loosely to itself.
More than anyone wanted to know about bearings...

[HP-Agilent-Keysight-equipment] HP 140 Series Fan Noise What
typically happens to bronze sleeve bearings istwo things:1) the
oil that impregnates the bronze foam runs short,?? and no
longer wicks up to the shaft/bronze interface2) the bronze
without oil is abrasive, and wears away?? the steel shaft until
it is small enough that it cannot?? be fully supported on a
film of oil.? This allows the shaft to rattle around in the
bronze hole, making noise and doing more damage.When you oil up
such a mess, the oil will not soak into thebronze "sponge",
because the friction smears the bronze untilall of the pores in
its hole are closed.? The oil in the now too large gap just
gets slung away until it is onceagain dry and making noise.A
new bronze/oilite bearing can be substituted, but you
willprobably find that one that is undersized enough to fit in
the worn section of the shaft, will be too tight to fitover the
un worn shaft.? The solution is to reduce the shaftsize just
enough to fit through the new bearing...-Chuck HarrisOn Sun, 7

Re: Agilent 54622D with broken digital inputs - Fixable?
Use proper (= leaded) solder instead of the early, so-so, RoHS soldering on those scopes. That might help.
While there: carefully check for tin whiskers too!

Re: HP 140 Series Fan Noise
Again, no telling what went on with it before I got it; however, I don't hear any of those sounds. The noise I hear reminds me more of a model airplane engine (e.g. a 0.049", etc.) only quieter than that.

When an oilite bearing fails, it forces the shaft to
move in and out... basically, dipping its toes into
the unworn shaft area.
The noise it makes sounds like "brum brum brum..."
The next phase is when the bearing gap becomes too wide
to work without the shaft bouncing between contacts with
the oilite.
The noise this makes is a squegging sound. While the
bounce is happening, the shaft is stealing significant
power, so often the squegg stops when a certain speed is
hit.
During the squegging phase, metal is often rolled up out
of the bronze and the shaft will try out seizing. Lots
of high pitched squealing happens before the shaft freezes.
The only of these phases that can be saved with lubrication,
long term, is the brum brum brum phase...

When I had the bushing pulled from the shaft, cleaned the ID of the
bushing with IPA and a cotton swab. I noted that there was just a
bit of something black that came off on the swab and I presume that
was either carbon from the bushing or from the shaft itself. If
bushing wear is an issue and an exact replacement bushing isn't
available, then I'm just going to leave it alone as I don't have a
machine shop handy.
While it might have run low on lubricant at some point in the last
~54 years (the main transformer has July 09, 1970 stamped on it), it
did have a decent amount of oil on the shaft and bushing when I
disassembled it.
I take it that some motors in the 140-series that, perhaps, have been
maintained properly are not this noisy?

Hi Jim,
Like it or not, oilite (aka sintered bronze) is more than just the
bronze that forms its structure.
Oilite, is made through a process called sintering. What is done
is bronze particles and carbon particles are mixed together with a
glue (binder) to form a thick paste, which is then packed into a
bearing shaped mold and dried.
The resulting bearing shaped object is put into a kiln and heated in
an inert atmosphere until the bronze particles just melt forming a
foam like structure filled with carbon and binder. The kiln is
then cooled to below melting, and air is introduced, causing the hot
carbon, and binder to burn away... without remelting the bronze.
Left behind are remnants of the carbon binder which are in the form
of carbides and other hard, abrasive, substances.... Oh well!
When the oilite bronze foam is filled with oil, the oil wicks out
and forms a meniscus of oil between the shaft and the oilite, on
which the shaft floats... never making contact with the oilite.
Steel floating on a meniscus of oil is the foundation on which most
lubrication works...
When the oil invariably evaporates, the shaft stops floating, and
is let down to run on the bronze. When this happens, the shaft is
running against the oilite bronze matrix, and comes into contact
with the hard abrasive materials that were left behind when the
oilite bronze matrix was made.
Most folks know that some forms of carbon, notably diamond are very
abrasive substances. What most don't know is all forms of carbon
are abrasive.
What about graphite, you say?
Graphite is slippery because it is composed of sheets of carbon
where the atoms in the sheet are strongly bonded, but the bonds
between the sheets are very weak. This allows the sheets to stay
as sheets, but layers of sheets to slide loosely against each
other... kind of like they had ball bearings between them.
Graphite is useful as a bearing because it sticks strongly to the
bearing metals (shaft, etc...), protecting them, but only loosely to
itself.
More than anyone wanted to know about bearings...

[email protected] Subject: Re:
[HP-Agilent-Keysight-equipment] HP 140 Series Fan Noise What
typically happens to bronze sleeve bearings istwo things:1) the oil
that impregnates the bronze foam runs short,?? and no longer wicks
up to the shaft/bronze interface2) the bronze without oil is
abrasive, and wears away?? the steel shaft until it is small
enough that it cannot?? be fully supported on a film of oil.? This
allows the shaft to rattle around in the bronze hole, making noise
? and doing more damage.When you oil up such a mess, the oil will
not soak into thebronze "sponge", because the friction smears the
bronze untilall of the pores in its hole are closed.? The oil in
the now too large gap just gets slung away until it is onceagain
dry and making noise.A new bronze/oilite bearing can be
substituted, but you willprobably find that one that is undersized
enough to fit in the worn section of the shaft, will be too tight
to fitover the un worn shaft.? The solution is to reduce the
shaftsize just enough to fit through the new bearing...-Chuck

Re: HP 140 Series Fan Noise
When an oilite bearing fails, it forces the shaft to move in and out... basically, dipping its toes into the unworn shaft area. The noise it makes sounds like "brum brum brum..." The next phase is when the bearing gap becomes too wide to work without the shaft bouncing between contacts with the oilite. The noise this makes is a squegging sound. While the bounce is happening, the shaft is stealing significant power, so often the squegg stops when a certain speed is hit. During the squegging phase, metal is often rolled up out of the bronze and the shaft will try out seizing. Lots of high pitched squealing happens before the shaft freezes. The only of these phases that can be saved with lubrication, long term, is the brum brum brum phase... -Chuck Harris On Mon, 8 Apr 2024 10:17:48 -0400 (EDT) "n4buq" <n4buq@...> wrote: When I had the bushing pulled from the shaft, cleaned the ID of the
bushing with IPA and a cotton swab. I noted that there was just a
bit of something black that came off on the swab and I presume that
was either carbon from the bushing or from the shaft itself. If
bushing wear is an issue and an exact replacement bushing isn't
available, then I'm just going to leave it alone as I don't have a
machine shop handy.
While it might have run low on lubricant at some point in the last
~54 years (the main transformer has July 09, 1970 stamped on it), it
did have a decent amount of oil on the shaft and bushing when I
disassembled it.
I take it that some motors in the 140-series that, perhaps, have been
maintained properly are not this noisy?

Hi Jim,
Like it or not, oilite (aka sintered bronze) is more than just the
bronze that forms its structure.
Oilite, is made through a process called sintering. What is done
is bronze particles and carbon particles are mixed together with a
glue (binder) to form a thick paste, which is then packed into a
bearing shaped mold and dried.
The resulting bearing shaped object is put into a kiln and heated in
an inert atmosphere until the bronze particles just melt forming a
foam like structure filled with carbon and binder. The kiln is
then cooled to below melting, and air is introduced, causing the hot
carbon, and binder to burn away... without remelting the bronze.
Left behind are remnants of the carbon binder which are in the form
of carbides and other hard, abrasive, substances.... Oh well!
When the oilite bronze foam is filled with oil, the oil wicks out
and forms a meniscus of oil between the shaft and the oilite, on
which the shaft floats... never making contact with the oilite.
Steel floating on a meniscus of oil is the foundation on which most
lubrication works...
When the oil invariably evaporates, the shaft stops floating, and
is let down to run on the bronze. When this happens, the shaft is
running against the oilite bronze matrix, and comes into contact
with the hard abrasive materials that were left behind when the
oilite bronze matrix was made.
Most folks know that some forms of carbon, notably diamond are very
abrasive substances. What most don't know is all forms of carbon
are abrasive.
What about graphite, you say?
Graphite is slippery because it is composed of sheets of carbon
where the atoms in the sheet are strongly bonded, but the bonds
between the sheets are very weak. This allows the sheets to stay
as sheets, but layers of sheets to slide loosely against each
other... kind of like they had ball bearings between them.
Graphite is useful as a bearing because it sticks strongly to the
bearing metals (shaft, etc...), protecting them, but only loosely to
itself.
More than anyone wanted to know about bearings...

[HP-Agilent-Keysight-equipment] HP 140 Series Fan Noise What
typically happens to bronze sleeve bearings istwo things:1) the oil
that impregnates the bronze foam runs short,?? and no longer wicks
up to the shaft/bronze interface2) the bronze without oil is
abrasive, and wears away?? the steel shaft until it is small
enough that it cannot?? be fully supported on a film of oil.? This
allows the shaft to rattle around in the bronze hole, making noise
? and doing more damage.When you oil up such a mess, the oil will
not soak into thebronze "sponge", because the friction smears the
bronze untilall of the pores in its hole are closed.? The oil in
the now too large gap just gets slung away until it is onceagain
dry and making noise.A new bronze/oilite bearing can be
substituted, but you willprobably find that one that is undersized
enough to fit in the worn section of the shaft, will be too tight
to fitover the un worn shaft.? The solution is to reduce the
shaftsize just enough to fit through the new bearing...-Chuck

Re: HP 140 Series Fan Noise
Bronze, being porous, can pick up and retain dirt, which, mixed with oil, becomes grinding compound. That¡¯s what wears the steel axle.?
Interesting that bronze would wear away steel; I thought that steel was much harder.? But I could be wrong.? That happened once before! ;)? ? ? ? ? Jim Ford

What typically happens to bronze sleeve bearings is two things: 1) the oil that impregnates the bronze foam runs short, ?? and no longer wicks up to the shaft/bronze interface 2) the bronze without oil is abrasive, and wears away ?? the steel shaft until it is small enough that it cannot ?? be fully supported on a film of oil.? This allows the ?? shaft to rattle around in the bronze hole, making noise ?? and doing more damage. When you oil up such a mess, the oil will not soak into the bronze "sponge", because the friction smears the bronze until all of the pores in its hole are closed.? The oil in the now too large gap just gets slung away until it is once again dry and making noise. A new bronze/oilite bearing can be substituted, but you will probably find that one that is undersized enough to fit in the worn section of the shaft, will be too tight to fit over the un worn shaft.? The solution is to reduce the shaft size just enough to fit through the new bearing... -Chuck Harris On Sun, 7 Apr 2024 13:59:11 -0400 (EDT) "n4buq" < n4buq@...> wrote: > That sounds like some slick stuff.? :) > > At this point, I'm reasonably sure the problem is not lubrication but > just an inherent property of the fan. > > Thanks, > Barry - N4BUQ > > > Greetings, > > > > There may yet be a solution.?

Re: HP 140 Series Fan Noise
When I had the bushing pulled from the shaft, cleaned the ID of the bushing with IPA and a cotton swab. I noted that there was just a bit of something black that came off on the swab and I presume that was either carbon from the bushing or from the shaft itself. If bushing wear is an issue and an exact replacement bushing isn't available, then I'm just going to leave it alone as I don't have a machine shop handy.
While it might have run low on lubricant at some point in the last ~54 years (the main transformer has July 09, 1970 stamped on it), it did have a decent amount of oil on the shaft and bushing when I disassembled it.
I take it that some motors in the 140-series that, perhaps, have been maintained properly are not this noisy?
Thanks,
Barry - N4BUQ

Hi Jim,
Like it or not, oilite (aka sintered bronze) is more than just the
bronze that forms its structure.
Oilite, is made through a process called sintering. What is done
is bronze particles and carbon particles are mixed together with a
glue (binder) to form a thick paste, which is then packed into a
bearing shaped mold and dried.
The resulting bearing shaped object is put into a kiln and heated in
an inert atmosphere until the bronze particles just melt forming a
foam like structure filled with carbon and binder. The kiln is
then cooled to below melting, and air is introduced, causing the hot
carbon, and binder to burn away... without remelting the bronze.
Left behind are remnants of the carbon binder which are in the form
of carbides and other hard, abrasive, substances.... Oh well!
When the oilite bronze foam is filled with oil, the oil wicks out
and forms a meniscus of oil between the shaft and the oilite, on
which the shaft floats... never making contact with the oilite.
Steel floating on a meniscus of oil is the foundation on which most
lubrication works...
When the oil invariably evaporates, the shaft stops floating, and
is let down to run on the bronze. When this happens, the shaft is
running against the oilite bronze matrix, and comes into contact
with the hard abrasive materials that were left behind when the
oilite bronze matrix was made.
Most folks know that some forms of carbon, notably diamond are very
abrasive substances. What most don't know is all forms of carbon
are abrasive.
What about graphite, you say?
Graphite is slippery because it is composed of sheets of carbon where
the atoms in the sheet are strongly bonded, but the bonds between the
sheets are very weak. This allows the sheets to stay as sheets, but
layers of sheets to slide loosely against each other... kind of like
they had ball bearings between them.
Graphite is useful as a bearing because it sticks strongly to the
bearing metals (shaft, etc...), protecting them, but only loosely to
itself.
More than anyone wanted to know about bearings...

Re: HP 140 Series Fan Noise
Hi Jim, Like it or not, oilite (aka sintered bronze) is more than just the bronze that forms its structure. Oilite, is made through a process called sintering. What is done is bronze particles and carbon particles are mixed together with a glue (binder) to form a thick paste, which is then packed into a bearing shaped mold and dried. The resulting bearing shaped object is put into a kiln and heated in an inert atmosphere until the bronze particles just melt forming a foam like structure filled with carbon and binder. The kiln is then cooled to below melting, and air is introduced, causing the hot carbon, and binder to burn away... without remelting the bronze. Left behind are remnants of the carbon binder which are in the form of carbides and other hard, abrasive, substances.... Oh well! When the oilite bronze foam is filled with oil, the oil wicks out and forms a meniscus of oil between the shaft and the oilite, on which the shaft floats... never making contact with the oilite. Steel floating on a meniscus of oil is the foundation on which most lubrication works... When the oil invariably evaporates, the shaft stops floating, and is let down to run on the bronze. When this happens, the shaft is running against the oilite bronze matrix, and comes into contact with the hard abrasive materials that were left behind when the oilite bronze matrix was made. Most folks know that some forms of carbon, notably diamond are very abrasive substances. What most don't know is all forms of carbon are abrasive. What about graphite, you say? Graphite is slippery because it is composed of sheets of carbon where the atoms in the sheet are strongly bonded, but the bonds between the sheets are very weak. This allows the sheets to stay as sheets, but layers of sheets to slide loosely against each other... kind of like they had ball bearings between them. Graphite is useful as a bearing because it sticks strongly to the bearing metals (shaft, etc...), protecting them, but only loosely to itself. More than anyone wanted to know about bearings... -Chuck Harris -Chuck Harris On Mon, 08 Apr 2024 04:41:53 -0700 "Jim Ford" <james.ford@...> wrote: Interesting that bronze would wear away steel; I thought that steel

[HP-Agilent-Keysight-equipment] HP 140 Series Fan Noise What
typically happens to bronze sleeve bearings istwo things:1) the oil
that impregnates the bronze foam runs short,?? and no longer wicks up
to the shaft/bronze interface2) the bronze without oil is abrasive,
and wears away?? the steel shaft until it is small enough that it
cannot?? be fully supported on a film of oil.? This allows the
shaft to rattle around in the bronze hole, making noise?? and doing
more damage.When you oil up such a mess, the oil will not soak into
thebronze "sponge", because the friction smears the bronze untilall
of the pores in its hole are closed.? The oil in the now too large
gap just gets slung away until it is onceagain dry and making noise.A
new bronze/oilite bearing can be substituted, but you willprobably
find that one that is undersized enough to fit in the worn section of
the shaft, will be too tight to fitover the un worn shaft.? The
solution is to reduce the shaftsize just enough to fit through the
new bearing...-Chuck HarrisOn Sun, 7 Apr 2024 13:59:11 -0400 (EDT)

Re: HP 140 Series Fan Noise
Interesting that bronze would wear away steel; I thought that steel was much harder.? But I could be wrong.? That happened once before! ;)? ? ? ? ? Jim Ford

What typically happens to bronze sleeve bearings is two things: 1) the oil that impregnates the bronze foam runs short, ?? and no longer wicks up to the shaft/bronze interface 2) the bronze without oil is abrasive, and wears away ?? the steel shaft until it is small enough that it cannot ?? be fully supported on a film of oil.? This allows the ?? shaft to rattle around in the bronze hole, making noise ?? and doing more damage. When you oil up such a mess, the oil will not soak into the bronze "sponge", because the friction smears the bronze until all of the pores in its hole are closed.? The oil in the now too large gap just gets slung away until it is once again dry and making noise. A new bronze/oilite bearing can be substituted, but you will probably find that one that is undersized enough to fit in the worn section of the shaft, will be too tight to fit over the un worn shaft.? The solution is to reduce the shaft size just enough to fit through the new bearing... -Chuck Harris On Sun, 7 Apr 2024 13:59:11 -0400 (EDT) "n4buq" <n4buq@...> wrote: > That sounds like some slick stuff.? :) > > At this point, I'm reasonably sure the problem is not lubrication but > just an inherent property of the fan. > > Thanks, > Barry - N4BUQ > > > Greetings, > > > > There may yet be a solution.?
