Flywheel and Ring Gear Inspection
(16-01)
Check the ring gear teeth for wear or damage. Use the
dye penetrant method to check the mounting holes for
cracks. Check the clutch face surface for cracks or dam-
age. If equipped with a flexplate, check the flexplate for
cracks or damage.
NOTE: If the ring gear teeth are worn or damged, the ring
gear must be replaced.
Ring Gear Replacement (16-02)
Brass Drift Pin
Warning: Wear eye protection when you drive the gear
from the flywheel. Do not use a steel drift pin.
Use the drift pin to drive the ring gear from the flywheel.
NOTE: The ring gear on flexplate applications cannot be
replaced as a separate unit. The entire flexplate assembly
must be replaced.
Heat the new ring gear for 20 minutes in an oven pre-
heated to 127C [260F].
Warning: Wear protective gloves when you install the
heated gear.
Install the gear. The gear must be installed so the bevel
on the teeth is toward the crankshaft side of the flywheel.
