Case Bearing Installation

[Jacob J.]

I have a pair of 6202 sitting for a rebuild that i think were for a 440 or a 460 ..??

A 6202 would fit the flywheel side of a 440 or 460, but not the PTO (clutch) side.

I thought i was having trouble with the MS260 Flywheel side bearing not going in enough but found yesterday after pressing it back out that the replacement bearing i got was at least 1/8" thicker than the Original.brand is niachi from japan.anyone else found this problem?

6002 is the usual generic size for the 024/026/MS-260 but you have to be careful. Most manufacturers make a regular 6002 that's 11mm wide and the stock bearing is 10mm wide. But, they also make a 6002D that's 13mm wide and it sounds like that's what you have.

I need to be taking notes.

One thing I will suggest for you fellows out there installing bearings. You should get yourself a digital caliper and familiarize yourself with how to measure a bearing for size. You might get the right bearing from a real bearing house distributor but several times I have been handed a bearing in a clear plastic wrap and was told it was what I was looking for, good thing I can read a caliper. Its saved me many times from doing a job more than once. Usually a bearing is measured by giving the inside diameter /shaft diameter first, then the outer race diameter followed by the width of the outer bearing race. This would look like 25 mm X 55mm X 10mm for a theoritical bearing.

Jerry that is great information and always good to know. I have learned to write down 25mm ID 55mm OD and 10mm thick and hand that to the parts guy.

That is very good info also Scott, just add another m after the 10m thick.
With it written down that way there are no if`s and butt`s about what you want. I just go to the counter where I get my stuff and rattle off the bearing number and the dimensions and get what I am looking for, 90% of the time they get it right but a few times I got a bearing a mm to wide , not what I asked for so now I get them to measure it right there at the counter. Most of the staff there know me and don`t think it strange that I ask them to measure it, a new face once in a while has asked,What don`t you trust me?? ....LOL

The other "m" is at the top of the post. Don't ask my how it go there.

i just split the case on an 064 tonight and figured this would be a good thread to reference for pointers/tips…it is…but i have a question…do you have a preferred/recommended way of removing the bearings from the case? I'm a little scared to clap the case out by beating them with a hammer and socket crooked…my aims never been the straightest haha….ive done it on 200t's but never a larger case saw….i wonder if you'll get an email or alert?? oh well...

If you heat the case with a torch, don`t get the flame close enough to burn the paint but get the case hot quickly, then slam it down hard on the benchtop gasket side downward the bearing will pop out on its own.

Ok,...I fixed that for you Scott.

I use a heat gun. Its safer I feel and easier on the case. After I warm it up I place the case on a bench vise and tap the bearing out. New bearing goes in the same way.

Thanks for the fix!!!

I use an arbor press and an appropriately sized socket to remove bearings with the case moderately heated before hand.

A word of advice when using a socket with a press...make sure it isn't a tapered socket. I learned the hard way on an 066 case when the bearing popped loose under enough pressure for the socket to get driven into the seal bore (small flywheel side) far enough to actually ruin that case half. Yeah. That sucked.

I use a press and heat. I did the heat and workbench vise prior to getting a press.

Nice thread......I wish emails still worked like they once did.

Try posting in the site support section. I'll bet Claudio fixes you right up.

Is there a masterminded method of removing the bearings from the case?
