Arbor press. Turn in a socket head cap screw into the crankshaft as far as it will go. Then press the crankshaft off the drive plate. I have done this to an Olympic I replaced the drive plate on.

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. Laughing 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. Small Cox Logo

Thanks Ian

Will check on the high speed bearings for mine.
Like to use the ones with the Plastic (if you will) retainers.
and the front one with seal.
