ISM, ISMe, and QSM11 – 016-008   Flywheel Ring Gear

WARNING  To reduce the possibility of severe eye damage, wear eye protection when you drive the ring gear from the flywheel. Do not use a steel drift.

CAUTION  Do not use a cutting torch to heat the ring gear. The flywheel can be damaged.

Heat the outside surface of the ring gear with a heating torch.

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

Do not attempt to install the ring gear without using heat.

Use an oven to heat the new ring gear for a minimum of one hour. Do not heat the ring gear for more than 6 hours.

Do not exceed the specified time or temperature.

If an oven is not available, use a heating torch to heat the gear. Use a Tempilstik crayon, or equivalent, to check the temperature of the gear.

A more even temperature is obtained by placing the ring gear on a metal plate and then heating the bottom side of the plate with the torch. Do not exceed the specified temperature.

WARNING  To reduce the possibility of severe burns, wear protective gloves when installing the heated ring gear.

Install the ring gear on the flywheel before it cools. Allow the air to cool the gear. Do not use water or oil to reduce the cooling time.
