Clutch: Adjustments

The clutch release mechanism on these models is hydraulically operated, and is not adjustable. When the clutch pedal is depressed, the pedal push rod contacts a plunger in the clutch master cylinder bore. The plunger first closes off the master cylinder fluid return port, then when moved further, forces fluid under pressure into the clutch actuating cylinder. As pressure is applied to the actuating cylinder, the actuating cylinder piston is forced outward activating the clutch release fork. To diagnose malfunctions in the clutch release system, proceed as follows:

1. With engine running at normal operating temperature and brakes applied, hold clutch pedal in fully depressed position and move transmission selector between 1st and reverse several times.

2. If transmission selector can be moved without binding or gear clash, clutch is releasing properly.

3. If shifter cannot be moved or if gear clash is evident, inspect clutch pedal bushings for damage and wear, and replace as needed.

4. If bushings are satisfactory, check clutch pedal travel.

5. Clutch pedal travel should be 6.25 inch.

6. If clutch pedal travel is not as specified, bleed hydraulic clutch system.
