Replace a worn or broken ring gear (2) as follows:
Wear protective clothing to prevent personal injury from burns.
Adjust the torch to a,good heating flame. Do not use a cutting flame (blue flame) to heat the ring
gear. Damage to the flywheel can result.
Use a torch to heat the ring gear (2).
If a torch is not available, the ring gear can be removed with a brass drift and hammer. If this
method is used, support the gear ring on a wooden block.
Use a brass drift and hammer and drive the old gear (2) from the flywheel (3).
Inspect the flywheel (3) (the ring gear seat area) for damage.
Use protective clothing to prevent personal injury from burns.
Do not attempt to install the gear without using heat. Do not exceed the specified temperature.
Damage to the gear will result.
Heat the new ring gear (2) in an oven to 450 (235 ) from 1 to 6 hours, or use a heating torch
not a cutting torch -- from the inside diameter of the gear so the heat travels outward to the teeth.
Stroke the gear while heating with a Tempilstick crayon, 600 (316 ) several times to prevent
The crayon will leave a chalk mark up to 6000F (316 ), then will leave a liquid smear.
Overheating the ring gear to 660 (349 ) will soften the gear and make it useless.
