Dome side just sits into crankshaft. Just make sure its straight up with crankshaft pryor to installing flywheel. Use some grease between crank and flywheel in case it needs to be removed again. BTW, Why did you have to change key? post back results.

NO grease. Crank taper and flywheel bore must be clean and dry (no oil, grease or anything else). Flywheel nut must be torqued to correct value. If the old key sheared, it's about 99.9% likely the flywheel nut wasn't properly torqued. You only get a few tries to get it right, before the flywheel and crankshaft become junk.

The stamp marks go in the crank slot and the straight edge must be parallel to the crank CL.

This is what the manual says for a 9 1/2 HP motor.
