Installation of a Typical 15½-Inch Clutch

Begin the installation procedure by ensuring that the work area is clear and that all component mating surfaces are clean.

1. Insert two 7⁄16-inch (5 inches long) guide studs into the two upper mounting holes of the flywheel.

2. Rotate the flywheel to level the guide studs.

3. Insert the aligning tool through the release bearing sleeve into the new clutch.

4. Guide the rear friction disc onto the aligning tool with the side stamped “pressure plate” facing the pressure plate.

5. Place the intermediate plate in the clutch cover and align the driving lugs of the plate with the slots provided. The separator pins in the intermediate plate must be flush with the lugs on the pressure plate side.

6. Install the front friction disc onto the aligning tool with the side stamped “flywheel” facing the engine.

7. Remember: It is essential that the side stamped “flywheel” faces the engine and the side stamped “pressure plate” faces the transmission. The relative positions of the buttons on the front and rear driven discs are not important.

8. If equipped, make sure that the Kwik-Adjust mechanism is aligned with the opening in the bell housing of the transmission.

9. Position the clutch pack over the guide studs and slide it forward until contact is made with the flywheel surface. Because a 15½-inch clutch assembly weighs over 150 pounds, a hoist may be required to lift it into place.

10. Start six 7⁄16-inch × 2¼-inch grade 5 mounting bolts with lock washers and tighten them finger tight .

11. Lightly tap the aligning tool to make sure it is centered and seated into the pilot bearing. Remove the guide studs and replace them with bolts and lock washers.

12. Tighten the bolts in the crisscross pattern sequence to pull the clutch into position in the flywheel. You should start with the lower left-hand bolt. Failure to tighten the bolts in this manner can cause permanent damage to the clutch cover or create an out-of-balance condition. To achieve the final torque, progressively tighten all bolts to 45 to 50 lb-ft. Note: As the bolts are tightened, the wooden spacers should fall out. If they do not fall free, remove them. This is important because the clutch will not function with the spacer blocks in place. After removing the spacer blocks, remove the aligning tool. You may have to lightly tap on the aligning tool with a mallet to remove it.

13. Using a ¼-inch diameter flat nose drift, lightly tap each of the four positive separator pins toward the flywheel. After tapping, the pins should be flush against the flywheel.
