GM Celebrity/Century/Ciera/6000 1982-1996 Repair Guide



The clutch driven disc may contain asbestos, which has been determined to be a cancer causing agent. Never clean clutch surfaces with compressed air! Avoid inhaling any dust from any clutch surface! When cleaning clutch surfaces, use a commercially available brake cleaning fluid.

On 1982-86 models the only service adjustment necessary on the clutch is to maintain the correct pedal free play. Clutch pedal free play, or throwout bearing lash, decreases with driven disc wear. On 1987 and newer models a hydraulic clutch system provides automatic clutch adjustment.


1982-86 Models

All cars use a self-adjusting clutch mechanism which may be checked as follows:

As the clutch friction material wears, the cable must be lengthened. This is accomplished by simply pulling the clutch pedal up to its rubber bumper. This action forces the pawl against its stop and rotates it out of mesh with the quadrant teeth, allowing the cable to play out until the quadrant spring load is balanced against the load applied by the release bearing. This adjustment procedure is required every 5,000 miles or less.

  1. With engine running and brake on, hold the clutch pedal approximately 1 / 2 in. (13mm) from floor mat and move shift lever between first and reverse several times. If this can be done smoothly without clashing into reverse, the clutch is fully releasing. If shift is not smooth, clutch is not fully releasing and linkage should be inspected and corrected as necessary.
  3. Check clutch pedal bushings for sticking or excessive wear.
  5. Have an assistant sit in the driver's seat and fully apply the clutch pedal to the floor. Observe the clutch fork lever travel at the transaxle. The end of the clutch fork lever should have a total travel of approximately 1.5-1.7 in. (38-43mm).
  7. If fork lever is not correct, check the adjusting mechanism by depressing the clutch pedal and looking for pawl to firmly engage with the teeth in the quadrant.
