Component Tests and General Diagnostics

Clutch

Component Test

1. Slowly press and release the clutch pedal to see if the pedal is binding. Make sure the clutch pedal can be fully pressed and is not restricted by the floor mat. Verify the pedal return spring is present and is functioning correctly.

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

3. With the engine idling, the parking brake on and the clutch pedal up, gently move the gearshift lever into a forward or reverse gear, until gear clash can be heard. Slowly press the clutch pedal.

1. If the gears cease to clash (full disengage at mm (0.9843 in)- 38 mm (1.4961 in)from the floor), hold the pedal at the point of disengagement and increase engine to 4,000 rpm. If the clutch remains disengaged, it is functioning correctly.

2. Any concerns indicate a worn or damaged clutch. Repair as necessary.

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

1. If the engine stalls, the clutch is OK.

2. If the engine does not stall, the clutch is slipping. Repair as necessary.

5. Compare the road test results with the symptom chart. The chart is a list of conditions that are typical faults. REFER to Symptom Chart: Clutch Clutch.
