Olympic .15 crankshaft disassembly?

1st remove back plate, cylinder and piston. Set crank case standing up on a hard solid metal surface with a none stock bolt (as they are too soft) screw
down all the way. You want a short bolt. Tap gently with a metal flat hammer increase tap strength gradualy till the prop plate backs off the front of the crank shaft. Soak the crank case and bearings in acid till the problem disapears. JK if you must remove bearings after a good soaking over night
in your favorite solution do to a bad bearing the front one comes out easy i have found the back one can be fussy. I did the soak trick then heated the aluminum crank case with a hot air gun, catching the inner lip of the bearing it tapped right out from the back of the crank case.
