Clutch Assembly: Inspection
WARNING: This page is about a different car, the 2002 Saturn Vue. However, it is still accessible from the selected car via links, so may be relevant.
- Inspect the actuator release bearing for minimal bearing drag. Replace the actuator assembly if no or little drag is found. See CLUTCH ACTUATOR CYLINDER .
- Inspect the clutch pressure plate assembly surface for excessive wear, chatter marks, cracks or evidence of overheating, indicated by Blue discoloration. Replace the clutch pressure plate assembly if necessary.
- Using a straight edge and a feeler gage, inspect the clutch pressure plate assembly for warpage. Maximum allowable warpage is 0.006" (0.15 mm). Replace pressure plate if warpage exceeds specification.
- Inspect the clutch disc facings for oil or burnt spots. Inspect clutch disc for loose damper springs, hub or rivets. Replace the clutch disc if any components are broken or excessively loose.
- Inspect the flywheel ring gear for wear or damage. Replace the flywheel if damaged. Random Black spotting on the friction surface of the flywheel is normal. Inspect the flywheel to clutch disc contact surface for excessive wear, cracks, chatter marks or overheating, indicated by Blue discoloration. Repair or replace the flywheel if necessary.
- Using a dial indicator, for at least 2 revolutions, measure flywheel runout. Maximum allowable runout: is 0.006" (0.15 mm). Using a straight edge and a feeler gage, inspect the flywheel for warpage. Maximum allowable warpage is 0.006" (0.15 mm). Resurface or replace the flywheel if not within specification.
- If the flywheel is being replaced, remove and discard the flywheel-to-crankshaft bolts and remove the flywheel. Install flywheel and NEW flywheel-to-crankshaft bolts. Hand start the bolts. Tighten flywheel-to-crankshaft bolts in a crisscross pattern to specification. See TORQUE SPECIFICATIONS . See Fig 1 .
NOTE:
Random Black spotting on the friction surface of the clutch pressure plate assembly is normal.
