Removing bearings from crankcase

[Mark71gtx]

OK, I spilt the case on the MS650 and the bearings were shot as I suspected. The crank pulled out and both bearings stayed in the case halves. How do I get them out without destroying anything, and do they come out toward the outside if the saw, or inside? Thanks!

Inside. You can usually drive then out with a punch against the inner race through the hole. Lay the case half mating surface on a couple layers of cardboard aka my bench top.... And have at it. Heat is your friend.

Heat the area around the bearings with a heat gun, or a propane torch. Then drive them out to the inside.

+1! ..... but use a shop press if you have access to one.

all of the above.

Awesome! That is what I figured, but didn't want to damage the halves because I didn't ask. Thanks again!

just be pretty careful of where the seal sits in there.

A shop press is easiest. It also works well for re-installation.

I guess if I was looking at the flywheel side I could have answered my own question. Got them out. Thanks again!

I heat the case half then set it on a piece of cedar 4x4 to keep from damaging the mating surface. Then find a deep well socket suitable & BFH......
The rest should be self explanatory

My shed floor is plywood. I use full size towels that we "retired" from home use. I folded it several times and set a half on it. Then the heat and beat. Went smooth as silk!

i actually invested in one of the small harbor freight presses.done pressed probably 10 saws since thanksgiving.kind of a tight squeeze but a life saver in doing a bigger volume of saws.

A press is one of the best tools I ever bought. Mines also hf. My son loves crushing soda cans. He would crush everything I own if I allowed it.

I don't know exactly were you at but I could have pressed them out for you.
