If you have everything removed...MAG magnet, small crank gear, and all case screws...just tap it apart with a plastic deadblow hammer. The bearings are not a press fit to the crank.

If you have not removed the clutch assembly...you will need to! There are 3 case screws behind the clutch assembly.

yeah the motor is apart and i tried tapping the shaft with the small gear on the clutch side and no movement at all. it seems like there is something clipped in side or maybe a pin of some sort.
