I'm rebuilding a bike for a friend, 01 cr250r and the transmission shafts bearings are spinning in the cases. One of them I can almost just drop it in, I'm considering using .002 shim stock around the bearing to give it a press fit again. He doesn't want to buy new cases as it's just his mess around bike, so what I'm wondering is, is there an alternative to shimming it or would that be best route? I've measured the hole and bearing so I know what shim to use but thought I'd ask around since I would just buy new..

The Loctite 609 is the lowest grade bearing retainer that they make. And it has a working temp of up 300* and then it still takes about 400* to come loose. The engine will never get that hot and if it does your bearings are the last of your worries. 609 will also fill a gap of up to .010 which is way larger than what you have now.
Every motor Ive rebuilt had a few trans bearings that I could take in and out by hand.
Thats y they have blind bearing pullers. This is used for the bearing that is pressed in against a solid wall of the case.
Well it worked out perfect. Just need to trim extra shim and I'll be done
All set worked out great now it's time to assemble it...thanks for all the help
