Flywheel Inspection

Inspect the ring gear teeth for wear and damage.
Inspect the clutch disc mating surface on the flywheel for wear, cracks, and burning.
Measure the flywheel (A) runout using a dial indicator (B) through at least two full turns with the engine installed. Push against the flywheel each time you turn it to take up the crankshaft thrust washer clearance. If the runout is more than the service limit, replace the flywheel, and recheck the runout. Resurfacing the flywheel is not recommended.
Standard (New): 0.05 mm (0.002 in.) max.

Service Limit: 0.15 mm (0.006 in.)

Turn the inner race of the ball bearing (A) with your finger. The ball bearing should turn smoothly and quietly. Check that the ball bearing outer race fits tightly in the flywheel. If the race does not turn smoothly, quietly, or fit tight in the flywheel, replace the ball bearing.
