I always understood the best way was to lap the flywheel and crank together in a lathe.
Flywheel in chuck check with DTI .
Crank nose in live centre in tailstock and lap taper by hand.
Not a DIY job in a small lathe you need access to an industrial lathe to do this.
It will take a lot of lapping to lock up against the rear bearing, the dished washer should be dimpled so that it will be just gripped as the flywheel is pulled up on the taper.
