REMOVAL & INSTALLATION
See Figure 1
- Disconnect the negative battery cable.
- Remove the transaxle assembly from the vehicle. Refer to Drive Train of this repair guide.
- If equipped with a manual transaxle, remove the clutch assembly. Refer to Drive Train of this repair guide.
- Matchmark the position of the flywheel to the engine block.
- Keep the flywheel from turning, using a holding fixture if necessary, and remove the flywheel retaining bolts.
- Remove the flywheel from the engine.
- Clean and inspect the flywheel. On some engines, the ring gear may be replaced if damaged.
- Position the flywheel to the engine, aligning the matchmarks made during removal.
- Apply a light coat of Loctite® 262, or equivalent thread lock, to the flywheel retaining bolt threads. Be careful not to over-apply the sealant or it could overflow the bolt seat and cause the bolt to work loose during vehicle operation.
- Tighten the flywheel retaining bolts in a crosswise pattern. For most vehicles, tighten the bolts to 22 ft. lbs. (30 Nm), then tighten each bolt an additional 45-60 degree turn. For 1990 vehicles, tighten the bolts to 47 ft. lbs. (64 Nm) on automatic transaxles or to 58 ft. lbs. (78 Nm) for manual transaxles. For the 1.8L engine, do not tighten the bolts additionally over the 22 ft. lbs. (30 Nm) specification.
- If applicable, install the clutch assembly.
- Install the transaxle assembly to the vehicle.
- Connect the negative battery cable.
RING GEAR REPLACEMENT
See Figures 2 and 3
- Remove the flywheel.
- Tap around the edge of the flywheel at the gear side face using a hammer and brass bar. This will loosen the gear for removal.
- Remove the gear from the flywheel.
- Heat the new gear in an oven to a temperature approaching, but not exceeding, 200°F. If you do not trust your oven, keep the temperature down to 150-175°F.
- Using special gloves to protect your hands (oven mitts will probably be insufficient and it is painful way to find out), install the expanded ring gear to the flywheel. If necessary, drive the gear into contact with the flywheel.
- Allow the flywheel and ring gear assembly to cool to the ambient temperature. The ring gear will contract upon cooling, causing a tight interference fit on the flywheel.
- Measure the ring gear run-out. It must not exceed 0.00394 in. (0.1mm).
- Install the flywheel to the engine.
