c. Repair

(1) Recovering ear(8) from flywheel

assembly as follows:

(a) Place flywheel assembly (3),

crankshaft side down, on a solid flat

surface or hardwood blocks which fit

inside diameter of ring gear (8).

(b) Drive gear (8) off flywheel assembly

Work around circumference of ring

gear to avoid binding.

(2) Install ring gear (8) on flywheel (9) as follows:

(a) Place flywheel (9), crankshaft side up, on a solid flat surface.

Hot metal components dissipate heat quickly and will cause burns to personnel.

Wear heat-resistant gloves when handling heated parts. If you receive burns,

immerse burn in cold water and seek medical aid.

CAUTION

If a torch is used to heat ring

gear,

keep torch moving

around circumference of ear

to avoid hot spots. Do not eat

over 400°F (204°C) under any

circumstances.

Excessive

heat may destroy original heat

treatment. Apply heat-indicat-

ing crayon to work surface,

which melts at a predetermined

temperature, to determine heat

range.

(b) Place ring gear (8) on a metal surface and heat uniformly. Heat source can be a blow

torch, acetylene torch, or oven.

(c) After ring gear is heated, place it in position on flywheel (9).

NOT E
