PINPOINT TEST A : CLUTCH SLIPPAGE

A1 TEST CLUTCH SLIPPAGE

- Apply the parking brake.

- Run the engine at approximately 2,000 rpm.

- Slowly release clutch pedal.

Does the engine stall when the clutch pedal is fully released?

No
GO to A2.

A2 MEASURE THE CLUTCH RESERVE

NOTE: Remove the floor mat, if equipped, to allow the clutch pedal to travel to the downstop.

- Install a cable tie to the lower clutch pedal, than attach a tape measure to the cable tie.





- Pull the tape measure up to the steering wheel. Position it through the steering wheel opening. Put a piece of masking tape on the wheel, index mark the tape.





- Press the clutch fully and start the vehicle.

- Shift the transaxle into reverse gear, then move the gearshift lever forward to the position in between reverse gear and neutral. Slowly release the clutch pedal (if the vehicle creeps rearward, move the gearshift lever forward a little more). The transaxle will work as if in neutral, but the reverse gear synchronizer will be bypassed.

- With the clutch pedal released, gently pull the gearshift lever toward the reverse gear position. Gear clash can now be heard.

- Slowly press the clutch pedal. Using the mark on the tape as a reference, note the measurement when the gear clash stops or the gearshift lever slides into reverse gear. Press the clutch pedal to the downstop. The difference between the measurement taken when the gear clash stopped and the measurement taken at the downstop is the clutch reserve.

Item Pedal Position 1 Gear clash begins 2 Gear clash ends 3 Clutch pedal downstop






Is the clutch reserve between 25-38 mm (1 to 1.5 in)?

Yes
Clutch pedal reserve is OK. VERIFY customer concern. GO to Symptom Chart - Clutch Symptom Chart - Clutch.
