Component Test

1. Verify the clutch hydraulic fluid reservoir is filled to the correct level.

1. If the fluid level is low, add fluid as necessary. Check the clutch hydraulic system for leaks and repair as necessary.

2. If the fluid is at the correct level, proceed to clutch check.

2. Apply and release the clutch pedal slowly to check for pedal binding. Make sure the clutch pedal can be fully applied and is not restricted by the floor mat. Verify the pedal return spring is present and functions correctly.

3. Measure the clutch reserve. REFER to Diagnostic Routine A: Clutch Slippage Diagnostic Routine A.

4. Set the park brake. The clutch pedal is in the up position and the engine idling, gently move the gearshift lever forward toward reverse gear until gear clash can be heard. Apply the clutch pedal slowly.

1. If the gears cease to clash (full disengage at25.4 mm (1 in) to 38.1 mm (1.5 in) from the floor), hold the clutch pedal at the point of disengagement and increase engine speed to 4,000 rpm. The clutch should remain disengaged, clutch OK.

5. With the engine idling and the clutch pedal applied, move the gearshift lever into 4th gear. Increase the engine speed to 2,000 rpm and slowly release the clutch pedal.

1. If the engine does not stall, clutch is slipping. Repair as necessary, REFER to Clutch Disc and Pressure Plate .

2. If the engine stalls, clutch is OK.
