Great Reed, That would be a big help. Thanks

Isn't that kind of wierd? The manuals all say to replace the spring. It's
not the balls which
wear out.

Reed (CA) >>

Unfortunately Reed, neither of my manuals say anything about the tower at
all, so they don't say to do this (at least not where I could find it).

Both of the balls in my tower assembly were galled from being dragged through
gritty grease (The dust covers were missing).

With the force required to put those springs back in I can't imagine that
they were bad, but they weren't put on a spring tester either so it's
possible they were weak. Of course I wouldn't have any idea what the proper
pressure for them would be. If I had new springs on hand I would certainly
put them in, but I wouldn't let it keep me from putting it back together if I
didn't have new ones.

If you have procedures for rebuilding the tower assembly I would love to see
them. That is exactly what I have been looking for to go with the T-90
rebuild kit. As I said before, I'm not an expert on T-90s and I'm always
open to new inputs.

It is weird that the balls aren't supposed to wear out but they are included
in the small parts kit and the springs that are supposed to wear out are not
included. Hmmmm.

Well, I have to make an apology. I gave up trying to scan, and started to type it out, only to
realize, two paragraphs down, that something wasn't right.

Turns out I was reading the write up for the side shift T-90. I can't find anything for the tower.
Isn't that dumb! Why give info for the least-, yet entirely leave out info for the most common.
I'll bet dollars to donuts, you'll find it in one of the military manuals. (Trouble shooting page
does say, "replace spring".)It's almost like they left the section out.

Who's got a military manual?

OK Reed,
Now it looks as though we are looking in the same book. You are right. It
makes absolutely no sense what so ever for them not put instructions in there
for rebuilding the tower. I even bought the second book hoping that it would
list the instructions. Of course if you have some mechanical skills, take
your time and don't force anything, you can figure it out. I don't think you
should have to do it that way.

John,
I didn't get to the tower last night. I got sidetracked by the Spurs game. I
have to pull apart Franks T-case today, but after I get done with that, I
hope to get back to the shift tower.

Who's got a military manual?

Me. What do you need to know? I haven't been keeping up on this
thread. Troubleshooting in shifter tower in Military manual mostly says
"inspect and replace any damaged or worn parts" no matter what the
symptoms are. This includes the poppet ball springs. The secret would
be to properly identify a worn spring. Broken, even I can figure out.

Ron, I think we were looking to see both if there was some smart way of disassembly, and any
technical info one needed to know. (The set up on the side shifter is very touchy).

Thanks for looking,

Okay--here goes my typing skills on display. No scanner. I gather you
are talking about the shift tower only, as all else has pretty well be
covered by Rick's rebuild.

Under disassembly:
Remove shifter fork pins from the second and high speed shifter fork and
the low and reverse speed shifter fork. Remove the two 3/8-inch
countersunk head pipe plugs. Slide the second and high speed gears
shifter shaft from gearshift control housing and remove low and reverse
speed shifter fork. Remove poppet ball and gearshift poppet ball
spring. Slide the low and reverse speed gears shifter shaft from the
gearshift control housing; remove second and high speed shifter fork.
Remove poppet ball and poppet ball spring. Remove gearshift rail hole
expansion plugs.


Now clean and inspect.

Inspect the transmission case and gearshift control housing for cracks
or damage of any kind. Any cracked or otherwise damaged units must be
replaced.

Replace the gearshift control housing if it is cracked or has stripped
threads. Replace the gearshift lever if it is excessively worn or
bent. Replace the gearshift control housing cap if it is bent or has
stripped threads. Replace the second and high speed gears shifter shaft
and second and high speed shifter fork if they are excessively worn, or
if they are bent or distorted. Replace the low and reverse speed gear
shifter shaft and low and reverse speed shifter fork if they are
excessively worn, or if they are bent or distorted. replace the
3/8-inch countersunk head pipe plugs if the threads are stripped.
Replace the gearshift lever support spring if it is cracked or
distorted. Replace the poppet balls and poppet ball springs if they are
worn, broken, or distorted.

On to assembly of subassemblies:

Assemble Gearshift Control Housing. Install new gearshift rail hole
expansion plugs into shifter shaft holes in end of gearshift control
housing. Insert poppet ball springs and poppet balls into gearshift
control housing while housing is placed upside down. Depress poppet
ball and poppet ball spring, and insert the low and reverse speed gears
shifter shaft into the gearshift control housing. Depress the other
poppet ball and poppet ball spring; install the second and high speed
gears shifter shaft into the gearshift control housing. Install the
second and high speed shifter fork onto the second and high speed gears
shifter shaft. Install the low and reverse speed shifter fork onto the
low and reverse speed gears shifter shaft. Secure both shifter forks
onto the shifter shafts with shifter fork pins. Flange the ends of the
gearshift fork pins with a center punch. Install 3/8-inch countersunk
head pipe plugs in ends of gearshift control housing.

Whew!!!!! I gotta get back to working on the airplane. This typing is
hard on the wrists. Please note the conspicuous absence of pictures.

Hope this helps, as I see no technical or special "tips" anywhere in
this manual. It is just the "facts" as required in motor pool or
rebuild shops.

Ron, IA
