Bleeding Procedure
HYDRAULIC CLUTCH LINKAGE
To determine if the master cylinder assembly requires bleeding or if the complete system requires bleeding:
1. Uncouple the clutch master cylinder line from the clutch slave cylinder. Use the quick disconnect tool (Special Tool 6638) to open the coupling.
2. Apply force to the clutch pedal to stroke it. Do not apply too much force as this will cause the uncoupled male coupling to blow out.
3. If the pedal feels hard in a relatively short distance, air is present in the clutch slave cylinder.
4. If the pedal feels spongy air is present in the master cylinder assembly.
COMPLETE SYSTEM
1. Remove the reservoir cap and diaphragm taking care not to damage the diaphragm. If the fluid level is not up to the step in the reservoir, add D.O.T. 3 brake fluid.
CAUTION: Use of fluid other than D.O.T. 3 compatible brake fluid will cause system malfunction.
2. While slowly depressing the clutch pedal, open the bleed screw on the clutch slave cylinder.
3. While holding down the clutch pedal retighten the bleed screw. Tighten the bleed screw to 15 - 20 Nm (11 - 14 ft. lbs.).
4. Repeat Step 2 and Step 3 two times. Recheck fluid level in reservoir per Step 1.
5. Pump the clutch pedal as rapidly as possible a minimum of 10 times.
6. If clutch pedal still feels spongy, repeat Step 2 through Step 5.
MASTER CYLINDER ASSEMBLY
1. Uncouple the master cylinder line from the clutch slave cylinder. Use the quick disconnect tool (Special Tool 6638) to open the coupling.
2. Remove the reservoir cap and diaphragm taking care not to damage the diaphragm. If the fluid level is not up to the step in the reservoir, add D.O.T. 3 brake fluid.
CAUTION: Use of fluid other than D.O.T. 3 compatible brake fluid will cause system malfunction.
3. Open the male quick connect coupling by depressing the poppet in the coupling while stroking the clutch pedal to the floor.
4. Close the quick connect coupling by releasing the poppet while holding the clutch pedal to the floor.
5. Release the pedal.
6. Repeat Step 3 through Step 5 two more times and check fluid level as in Step 2.
7. Couple system back together. Then pump clutch pedal as rapidly as possible a minimum of 10 times.
8. If clutch pedal still feels spongy repeat Step 3 through Step 7.
