Its called a 'blind hole bearing puller';

www.harborfreight.com/blind-hole-bearing-puller-95987.html

Can be made with simple stuff if studied..Heating the case with a heat gun and banging it on a 2X4 wood block will get them out lots of times also..
Good Luck,keep us posted!!

I'll let ya know so… you mean to bang the case on the 2x4 and the bearing will drop out (after heating of course). Will a propane torch work?

Has it failed for you vlatx?

I'll probably end up doing the bread technique. The 103cc build is on hold for a few weeks. We have a moped run memorial day weekend, so I got to get the bike back together before then. I'll just throw the 70cc back in, for that run, then its on. I'll haver a daily driver while I build the full stroker.

COOL!And you can eat it too!!The tree huggers oughta like this...
Really though,its a great idea,,the old school method used grease,but it would only work if tolerances were close,,the bread will take up the slack,great idea!!
