locking collar
 

I need to remove a pair of 2" diameter bearings on pillow blocks.

Way back when my sprayer was built, they put the locking collar on the
inside. That way, a farmer wouldn't take it apart!

Any suggestions on releasing the locking collar on a bearing when its
hard to get at? Other than the smoke wrench.

I just gave up for the day and let it soak in kroil over night.

Thought I'd try putting the 20 ton hydraulic puller on it before
supper. Solved my space problem on one bearing, the pillow block
EXPLODED. Got a hole in the sheet rock ceiling to fix now. And the
wife has to clean brown and yellow spots out of my shorts.

Well, Karl. I'd say that was the wrong way to approach it.

Look for snaprings and get the proper snapring pliers for it.

Or just buy another pair with _external_ snappers, wot?

At least you were wearing shorts. It would have been a bigger mess
without them. ;-)

Some of them have a spherical outer race, you need to first remove the shaft and then rotate the bearing in the spherical housing bore till it's aligned with the "keys" (which are located on only one side of the housing) at which point the bearing will basically fall out.

Yep, that's exactly how it was built. But the yoyo that assembled my
machine put this to the inside. Put this on correctly and a bearing
that has been in place for years can be easily removed. Good design,
but not idiot proof. At least the assembly shop had better idiots.

I busted one bearing all to hell, but that gives room to work on the
other one. When i get the puller repaired, that is.

Now need to go shopping for a 2 3/16 shaft bearing and pillow block.
