INSPECTION
Remove the crankshaft (page 16-17).
Turn the inner race of each crankcase bearing with
your finger. The bearing should turn smoothly and
quietly.
Also check that the bearing outer race fits tightly in
the crankcase.
Replace any bearing if the inner race does not turn
smoothly, quietly or if the outer race fits loosely in
the crankcase.
