Flywheel: Testing and Inspection

Flywheel Inspection









Removal

1. Pressure Plate





1. Install the ring gear holder.

2. Install the clutch alignment shaft and the remover handle.

3. To prevent warping, loosen the pressure plate mounting bolts (A) in a crisscross pattern in several steps.

4. Remove the pressure plate (B).

2. Clutch Disc





1. Remove the clutch disc (A), the clutch alignment shaft, and the remover handle.

Inspection

1. Flywheel 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 pushing against the flywheel each time you turn it to take up the crankshaft thrust washer clearance. If the measurement is more than the standard, replace the flywheel, and recheck the runout.








Installation

1. Clutch Disc





1. Temporarily install the clutch disc onto the splines of the transmission mainshaft. Make sure the clutch disc slides freely on the mainshaft.

2. Apply super high temp urea grease (P/N 08798-9002) to the splines (A) of the clutch disc (B).

NOTE: Wipe off any excess grease.

3. Install the clutch disc using the clutch alignment shaft and the remover handle.

2. Pressure Plate





1. Install the pressure plate (A) and the mounting bolts (B) finger-tight.





2. Torque the pressure plate mounting bolts (A) in a crisscross pattern.

NOTE:
* Tighten the bolts in several steps to prevent warping the diaphragm spring.
* Make sure that there is no clearance between the pressure plate and the flywheel.







3. Remove the ring gear holder.

4. Remove the clutch alignment shaft and the remover handle.

5. Make sure the diaphragm spring fingers are all the same height.
