Clutch Hydraulic System: Service and Repair

CLUTCH HYDRAULIC SYSTEM BLEEDING

MANUAL BLEEDING
1. Attach a clear line to bleed screw with loose end submerged in a small container of clutch fluid.





2. Actuate pedal five times at a normal speed by stroking it all the way to the pedal stop in both directions (down stop and up stop).
3. Actuate pedal quickly 10 - 15 times without bringing pedal all the way to up stop (30 - 40 mm [1.18 - 1.51 inch] short of stop at pedal).
4. Repeat steps 2 and 3 five times.
5. Hold pedal at up stop and open bleed screw.
6. Stroke pedal to the floor normally and close bleed screw.
7. Lift pedal to up stop position.
8. Repeat steps 5 through 7 three times.
9. Tighten bleed screw.
Torque: Bleed Screw: 7 Nm (62 inch lbs.)
10. Remove bleed line from bleed screw.

VACUUM BLEEDING





1. Torque bleed screws.
Torque: Bleed Screw: 7 Nm (62 inch lbs.)
2. Make sure pedal is in up position.
3. Fill reservoir with specified fluid to Max level.
4. Install 50 mm rubber stopper and attach to a Vacuum Pump J23738A (or equivalent) with a length of hose.
5. Place and hold stopper over top of reservoir to ensure a tight fit.
6. Operate pump to achieve 103 - 138 kPa (15 - 20 psi) on gauge.
7. Hold vacuum for approximately one minute.
8. Slowly relieve vacuum and remove stopper from reservoir.
9. Replenish fluid to proper level.
10. Repeat steps 5 through 9 two additional times.
11. Replace reservoir cap.

IMPORTANT: Clutch pedal will go to the floor on the first actuation, but should improve on the following actuations.

12. Actuate clutch pedal 10 - 12 times to ensure proper operation.
13. Test drive vehicle to ensure proper clutch operation and shifting.
