Flywheel, Flywheel Bearing
Inspect the ring gear teeth for wear and damage.
Inspect the clutch disc mating surface on the
flywheel fo. wear, cracks, and burning.
Measure the flywheel runout using a dial indicator
through at least two full tu.ns. Push against the
Ilywheel each time you turn it to take up the crank-
shaft thrust washe. clearance.
NOTE; The runout can be measu.ed with engine in-
stalled.
Standard (ttlervl: O.O5 mm (O.002 inl Max.
Service Limit: 0.15 mm 10.006 inl
RING GEABFLYWHEEL
DIAL II{DICATOR
It the runout is more than the service limit, leplace
the flvwheel.
Turn the inner race of the flywheel bearing with your
finger. The bearing should turn smoothly and quiet-
ly, Check that the bearing outer race fits tightly in
the flvwheel.
FLYWHEELBEARING
It the race does not turn smoothly, quietly, or fit
tight in the flywheel, replace the flywheel bearing.
Install the special tool.
Remov€ the flywhe€l mounting bolts in a criascross
pattern in several steps 8s shown, then remove the
