REMOVAL & INSTALLATION
The ring gear is replaceable only on engines mated with a manual transmission. Engines with automatic transmissions have ring gears which are welded to the flexplate.
- Remove the transmission.
- Remove the clutch, if equipped, or torque converter from the flywheel. The flywheel bolts should be loosened a little at a time in a crisscross pattern to avoid warping the flywheel. On cars with manual transmissions, replace the pilot bearing in the end of the crankshaft if removing the flywheel.
- The flywheel should be checked for cracks and glazing. It can be resurfaced by a machine shop.
- If the ring gear is to be replaced on manual transmissions, drill a hole in the gear between two teeth. Be careful not to contact the flywheel surface. Using a cold chisel at this point, crack the ring gear and remove it.
- Polish the inner surface of the new ring gear and heat it in an oven to about 600ºF (316ºC). Quickly place the ring gear on the flywheel and tap it into place, making sure that it is fully seated.
- Position the flywheel on the end of the crankshaft. Tighten the bolts a little at a time, in a crisscross pattern, to the tighten figure shown in the Torque Specifications chart.
- Install the clutch or tighten converter.
- Install the transmission. Refer to the necessary service procedures.
