CLUTCH DISC AND COVER REMOVAL / INSTALLATION
Removal
1 Remove the transmission. See Manual Transmission Removal / Installation.
2
CAUTION:If the clutch disc and clutch cover are to be reinstalled, remove the bolts evenly or permanent damage to the diaphragm spring will occur resulting in complete clutch release.
NOTE:If the parts are to be reused, mark the clutch cover and the flywheel.
Remove the bolts, clutch cover and the clutch disc.
3 Inspect the transmission input shaft pilot bearing:
- for misalignment and looseness in the crankshaft or flywheel.
- needle rollers for scoring, discoloration, wear and broken rollers.
- seal for damage and lubricant leakage.
- Install a new transmission input shaft pilot bearing if any of these conditions are present. See Service and Repair.

NOTE:Use an emery cloth to remove minor imperfections in the clutch disc friction surface.
Inspect the clutch disc for:
- oil and grease saturation.
- worn and loose rivets at the hub.
- broken springs.
- wear and rust on the splines.
- Install a new clutch disc if any of these conditions are present.

NOTE:If necessary, use a suitable cleaning solution to remove any oil film from the clutch pressure plate friction surface.
Inspect the clutch pressure plate levers for heavy wear associated with binding. Also, inspect for substantial difference in lever wear. Inspect the clutch pressure plate friction surface for scoring, burning, heat checking, distortion, warping and dishing.
- Install a new clutch pressure plate if any of these conditions are present.

NOTE:Use an emery cloth to remove minor imperfections in the clutch disc friction surface.
Inspect the flywheel for:
- surface cracks.
- heat check.
- glazing.
- scoring.
- scratches or grooves.
1 Inspect the flywheel or ring gear for worn, chopped or broken teeth.
Installation
1 Using front axle grease, lubricate the transmission input shaft pilot bearing.
2 Adjust the clutch pressure plate.
1 Using a suitable press, press downward on the fingers until the adjusting ring moves freely.
2 Rotate the adjusting ring counterclockwise to compress the tension springs. Hold the adjusting ring in this position.
3 Release the pressure on the fingers. The adjusting ring will stay in the reset position.
1 Using a suitable clutch aligner, position the clutch disc on the flywheel.
2
NOTE:If reusing the clutch pressure plate, align using marks made during removal.
Using a suitable aligner, align the clutch disc and the clutch pressure plate. Install the bolts and tighten in a star-pattern sequence.

NOTE:Before securing the transmission to the engine, connect the hydraulic line to the clutch slave cylinder.
Install the transmission. See Manual Transmission Removal / Installation.
