Removing Bearing inside crankcase?

[QUOTE="125rmcrazy, post: 1251193, member: 80131"] ive done many of these. working at a welding/machine shop you learn a few things. if you're changing the bearing the other one is garbage right. use a mig welder, weld a small bead all around the outside race of the bearing. once done, take a small peice of shafting.. put in the center of the bearing and weld that to the inside race. the bearing should pull out with your hands. for more stubborn ones, you use a threaded rod, with a peice of flatbar with a hole drilled in in, and a nut on the threaded rod on the outside of the flatbar. weld the threaded rod to the bearing, and tighten the nut. this works the same as a puller. i had to change 2 on my rm 125 rebuild not too long ago actually.. regards.
