    • Key in OFF position.
    • Apply the parking brake.
    • Depress and slowly release the clutch pedal.
    • Does the clutch pedal release without binding? 

    Yes  : GO to A2.

    No  : INSPECT the clutch pedal for wear or damage. REPAIR as necessary. REFER to CLUTCH CONTROLS .

  2. A2 TEST CLUTCH SLIPPAGE 
    • Apply the parking brake.
    • Start engine and engage 4th gear.
    • Run the engine at approximately 2,000 RPM.
    • Release clutch pedal slowly.
    • Does the engine stall when the clutch pedal is fully released? 

    Yes  : The clutch is not slipping. VERIFY customer concern.

    No  : GO to A3.

  3. A3 MEASURE THE CLUTCH RESERVE 
    • Apply the parking brake.
    • Start the engine.
    • With the clutch pedal up, gently move the shift lever toward the REVERSE gear position.
    • Hold the lever in position when gear clash can be heard.
    • Slowly depress the clutch pedal.
    • Stop and hold the clutch pedal when the gear clash stops. Measure the distance from when gear clash stops to the pedal fully depressed position. The difference between the measurement taken when the gear clash stopped and the measurement taken at the downstop is the clutch reserve.
