REMOVAL & INSTALLATION
See Figures 1 and 2
The ring gear is replaceable only on 1468cc, 1495cc and 2351cc engines mated with a manual transaxle. Engines with automatic transaxles have ring gears which are welded to the flex plate.
- 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 cross pattern to avoid warping the flywheel. On vehicles with manual transaxle, replace the pilot bearing in the end of the crankshaft if removing the flywheel.
On 1495cc engines with a manual transaxle, there is a crank angle sensor ring bolted to the flywheel. This ring must be removed before any repairs are done on the flywheel or ring gear.
- 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, drill a hole in the gear between two teeth, being 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 316°deg;C. Quickly place the ring gear on the flywheel and tap it into place, making sure that it is fully seated. Use proper hand protection when handling the flywheel.
Never heat the ring gear past 426°deg;C, or the tempering will be destroyed.
- Position the flywheel on the end of the crankshaft. Torque the bolts a little at a time, in a cross pattern, to the torque figure shown in the Torque Specifications Chart. On 1495cc engines with a manual transaxle, install the crank angle sensor ring and tighten the mounting bolts to 8.6-10.8 ft. lbs. (12-15 Nm).
- Install the clutch or torque converter.
- Install the transmission and transfer case.
