Flywheel: Service and Repair

INSPECTION
1. Inspect the ring gear teeth for wear and damage.
2. Inspect the clutch disc mating surface on the flywheel for wear, cracks, and burning.





3. Measure the flywheel runout using a dial indicator through at least two full turns. Push against the flywheel each time you turn it to take up the crankshaft thrust washer clearance.

NOTE: The runout can be measured with engine installed.

If the runout exceeds the service limit, replace the flywheel.





4. Turn the inner race of the ball bearing with your finger. The ball bearing should turn smoothly and quietly. If the inner race does not turn smoothly and quietly, replace the bearing. Check that the ball bearing outer race fits tightly in the flywheel. If it is loose, replace the ball bearing.

REPLACEMENT





1. Install the special tool.
2. Remove the flywheel mounting bolts in a crisscross pattern in several steps as shown, and remove the flywheel.





3. Remove the ball bearing from the flywheel.





4. Drive the new ball bearing into the flywheel using the special tools as shown.
5. Align the hole in the flywheel with the crankshaft dowel pin and install the flywheel. Install the mounting bolts finger-tight.





6. Install special tool, then torque the flywheel mounting bolts in a crisscross pattern in several steps as shown.
