facing the fan-side ball bearing
– Heat the inner race of the ball

crankshaft stub makes contact.
The crankshaft must be fitted
rapidly, as the heat is transmitted to
the crankshaft stub and the inner
bearing race contracts.
If the inner race cannot be heated,
the crankshaft can be drawn into the
crankcase with the assembly tool
