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.
