...My problem is I cannot figure out how to remove the shaft from the engine. Can you shed some light?

...Svik,

You will need some kind of a puller (gear, terminal, bearing), which will latch onto the slot in the prop-drive washer and press back against the crankshaft, to remove it from the lock-cone. There are several recent threads that have links to such equipment...

After that, undo the four bolts that hold the front crankcase to the rear and separate them (you will need to make/buy a new gasket for reassembly).

The crankshaft should be a firm push-fit in the bearings.

I would not take apart a running engine, to replace the crankshaft, with an untested replacement...

Can this short crankshaft issue, not be overcome with a special, tubular extension prop-nut, that you can machine on your CNC just the same???
