Does yours have the MT2 or MT3 shank? I see they made them up to MT5, mine is MT2. I've got some scraps of metal here I could make into a 2-piece collar, for that matter. Spent way too much money getting my wife set up to heal after her shoulder surgery late in October, and I'm officially done spending money on my new SB lathe until she says otherwise. ;) Gotta admit I milked it pretty good while I could. I'll hope the bearing can be cleaned out. Seems Amazon wants about $41 for the cheap one, and up like a skyrocket from there. I'll have to call Fleck Bearing, our local bearing shop, and see what they want.

Thanks a bunch for the info! I was trying to find it about a week ago, and not having any luck. Was gonna take a hack at it sometime this week and hope I didn't butcher it. I'll probably take it to work and put a little Mobile Polyrex EM in it. Thin, as greases go, very water & heat resistant. It's what is specified for all the monster motors on our mat machine, which has that 60hp motor I think I've mentioned here. Among 11 or 12 others, ranging down to 1.5hp.

Thanks again!

Hi Bill,

Here we go.

It's not real obvious how to take these guys apart as you may have noticed!

I drilled and tapped two 10-32 holes in the front cover plate and used a slide hammer to pull it out, not necessary as that didn't really help in the end and I had to make a new replacement!

Anyway, the od of the point on mine is around .740. Put a 3/4" shaft collar on it leaving a gap between that and the body and use 2 screwdrivers/ pry bars, whatever to extract the tip.

The shank is separate, use maybe a 1/2" diameter pin to push that out. I used my 10 ton Dake screw press, it's on a taper so when it pops, it's out. Put a box of rags or something under it so it doesn't get damaged.

Then flip it over and use something around 5/8" diameter to press out the bearing along with the front cover. Easy!

It uses a double row angular contact bearing, 3202 I believe. I was able to remove the cages intact for a good cleaning.

Old hardened grease was the problem. Looks almost new and runs like new.

?

Polish everything up and put it back together. I first used NLGI #2, had to do it again, too much drag so I switched to a Lithium #1. Shell Gadus S3 V220C1 to be exact, couple dollars at McMaster. I love that place and they're about 2 miles from my house! Don't use white lithium and don't over pack.

My youngest son was USAF, now he's Air National Guard and a high school "industrial technology" teacher, AKA machine shop.?

Hope this helps.

I may have something at work I can borrow, if necessary. I've made some small parts for them, so my boss is good about loaniong tools. Get yourself settled, and take your time. I retired from the USAF over 20 years ago, but still remember being jetlagged after getting home from some long trips.

Hi
Bill, I have more pics and can tell you the first
try way and the easy way to get it apart! Just
got home from Iceland yesterday but I'll try to do
something tomorrow.? Mine is nice and smooth now
and runs out less than .0002". You're
going to have to invest in a 3/4" 2 piece shaft collar
though, 1 piece clamp on could work as well. Set screw
collars are garbage. Dave

[atlas-craftsman IO] Royal live center
Dave,I
only see one pic, and I'm VERY interested because I got
one with my SB 10L lathe, and mine is more than "a
little crunchy." Poor baby spent some years in an open
barn. More photos would be welcome. More info on how you got
it apart, too. Mine spent a few days soaking in evaporust
after a day in purple power degreaser. Still real crunchy. I
have a small arbor press in the home shop, and a 20-ton HF
hydraulic press available at work. Looks like I'll need
a new bearing, from your photo.?


Thanks for a really timely
post!

Hi guys,?
I have a Royal
Products , Regal live center that either came with or was
purchased along with my dad's lathe. Whatever, first one
I ever used.?
Recently rebuilt it. Nothing
wrong except for the crunchy bearings due to dried up?
grease.?
Couple pics of the process.?
