Pilot bearing removal question

How about a picture so we can see what you are dealing with. Many of us have replaced these bearings, and may be able to help, but show us what your dealing with.

This one from Harbor Freight goes down to .375" so it should fit. I have it as well, and it actually works better for some situations than the one I posted from Amazon.

Thanks for the replies, but like I said the grease blew out the flimsy retainer and now I get no hydraulic action because the new grease just flies out between the bearings. I'd try a slide hammer but that again means buying the whole shindig of over $40 and all the ones I see also say 1/2" minimum id. Although that harbor freight hammer is cheap enough it might be worth a shot if all other ideas fail. I've got no welder so that approach is out. I thought of the anchor bolt idea but was thinking there is not much room below the bearing, maybe a half inch. Has anyone ever tried using something like clay or silly putty? Seems like the greater viscosity might slow down leakage thru the bearings now that the thin metal retaining ring is gone.

I tried removing my post but couldn't. What I had posted was for a brass pilot bearing.

Yes, he said it was a 6001z in his first post.

That doesnt tell me its a ball bearing. Best if info is stated up front.

Since it appears it has to be assumed it is a ball bearing this is a good stab at it. ... Another possibility would be a corn starch suspension in place of grease. If things like that dont work and a puller is too much there are many other nondestructive ways. They all involve making something.

The most gross would be to break the bearing cage and take out the inner race and balls. Gives a lot more room to work to remove the outer race.

Grease has always worked for me but that has always been on bushings, not a ball bearing.

What I would do is as larry suggested and break the inner race and let the balls out. Then you are dealing with just the outer race inside a 28mm bore. Lots more room to work. Then I would either grab my slide hammer with hook, or lay down a bead of weld around the outer race right inside where the balls normally would be. After that weld cools down, the race will just fall out.

He said he doesn't have a welder.
