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.
Heat the new ring gear in an oven heated to 316°C [600°F] for a minimum of 1 hour.
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 Tempilstikᮋ 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.
