Advice on a bearing removal

David_Darkes
I have a needle shift drum BLIND bearing that needs to be removed from a crankcase of a 2001 cr250. I have no special tools like a blind bearing puller. Is there a safe way of removing it without buying a bearing puller.

Thanks people

Not reaaaaaally. You can rent a blind bearing puller from autozone.

Put the side case on a hot plate and heat it up. The slam it down on a soft wooden surface to pop the bearing(more likely all of them) out. If that doesn't work, You'll need to buy a puller.

hydraulic it out.
1) fill the center of the bearing with grease
2) find bolt about the same size as the center hole
3) hit with hammer
4) re-fill with grease
5) hit with hammer
6) repeat step 4 and 5 as needed.

Of course a little bit of heat will help get it out of there too.

Try to tack weld a bolt on it and pull it out that way.

Had to do this procedure on my Mini Cooper recenty. Someone severely overtightened the drain plug and stripped the head. I agree with most above a puller would be ideal but sometimes you gotta make do.

I've seen people put the case in the oven center face down with the oven on 400 deg F. The aluminum will expand faster than the steel (but not much). If you're lucky, the bearing will drop out. If you're not.....well, it's still in there.
