Flywheel Ring Gear - Replacement

(16-02)

Caution: Do not use a cutting torch to heat the ring gear.

The flywheel can be damaged.

Heat the outside diameter of the ring gear with a heating

torch.

Use a blunt chisel and a hammer to remove the gear from

the flywheel.

Caution: Do not overheat the ring gear. The metal hard-

ness will be changed.

Heat the new ring gear in an oven heated to 316°C [600°F]

for a minimum of 1 hour.

Caution: Wear protective gloves when handling parts

that have been heated to prevent personal injury.

Remove the gear from the oven, and install it on the

flywheel before it cools.

NOTE: If an oven is not available, use a heating torch to heat

the inside diameter of the new ring gear to 316°C [600°F].

Use a TempilstikW crayon or its equivalent to check the gear

temperature before installing it on the flywheel. A more even

temperature can be obtained by placing the ring gear on a

metal plate, then heating the bottom side of the plate with a

heating torch. Do not exceed the specified temperature.
