Flywheel and Ring Gear

REMOVAL & INSTALLATION

All Engines

NOTE: The clutch cover and the pressure plate are balanced as an assembly; if replacement of either part becomes necessary, replace both parts as an assembly.

  1. Remove the transmission by using the procedures from Section 7.

    CAUTION
    The clutch disc contains asbestos, which has been determined to be a cancer causing agent. Never clean the clutch assembly with compressed air! Avoid inhaling dust from the clutch during disassembly. When cleaning components, use commercially available brake cleaning fluids.

  2. Remove the clutch assembly, if equipped — refer to Section 7.
  3. Most trucks equipped with automatic transmissions have separate drive plates, but the 2.0L engines have the ring gear attached to the torque converter. For all trucks except for the 2.0L engine trucks, remove the retaining bolts holding the adapter plate, the drive plate, the crankshaft adapter and the crankshaft bushing to the crankshaft. For trucks equipped with the 2.0L engine, remove the torque converter and examine the teeth on the ring gear.
  4. For trucks with manual transmissions, matchmark the flywheel and crankshaft. Loosen the retaining bolts evenly and in a crisscross pattern. Support the flywheel during removal of the last bolts and remove the flywheel.

    To install:

  5. Carefully inspect the teeth on the flywheel, torque converter, or drive plate for any signs of wearing or chipping. If anything beyond minimal contact wear is found, replace the unit.

    NOTE: Since the flywheel is driven by the starter gear, it would be wise to inspect the starter drive if any wear is found on the flywheel teeth. A worn starter can cause damage to the flywheel.

  6. When reassembling, place the flywheel or drive plate in position on the crankshaft and make sure the matchmarks align. Install the retaining bolts finger-tight. The torque converter should be reinstalled on the transmission, not on the engine.
  7. Tighten the flywheel or drive plate bolts in a diagonal pattern and in three passes to 98 ft. lbs. (133 Nm) for 4-cylinder engines or 54 ft. lbs. (74 Nm) for 6-cylinder engines.
  8. Install and adjust the clutch assembly.
  9. Install the transmission.
