Flywheel and Pilot Bearing Inspection and Replacement



Flywheel and Pilot Bearing 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 (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 not within the standard, replace the flywheel and rechecke the runout. Resurfacing the flywheel is not recommended.




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

Flywheel and Pilot Bearing Replacement





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




3. Remove the pilot bearing (A) from the flywheel (B).




4. Install the new pilot bearing (A) into the flywheel using the special tools. Apply a light coat of oil to the bearing surface.
5. Install the flywheel by aligning the crankshaft dowel pin with the hole in the flywheel, and install the mounting bolts finger-tight.




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