nal ends.
Inspect bearing (19) for looseness and evidence of overheating.
Inspect exciter rotor (22) for broken windings, evidence of overheating, damaged insulation, and other damage.
Inspect rotor assembly (18) for broken windings, evidence of overheating, damaged insulation, and loose termi-
nal ends.

ends, and damaged housing.
Inspect drive plate (9) and retention disk (15) for bends, cracks, elongated mounting holes, and other damage.
Inspect flywheel (10) for cracks, broken teeth, stripped threads, and other damage.
Inspect generator fan (8) for cracks, bent, or broken blades and other damage.
4-12-4. Repairir.
a.
If ring gear (11, Figure 4-25) is damaged, place the flywheel (10) on a solid flat surface.
b. Drive ring gear (11) off with a brass drift and hammer.
Oil fumes or oil can ignite above 380°F (193°C). Use a thermometer and do not
exceed 360° F (182°C). Do not allow a flame or heating element to be in direct con-
tact with oil. Heat oil in a well ventilated area. Plan a safe handling procedure to
avoid burns.
Wear protective gloves to help prevent burns from handling hot ring gear (4).
CAUTION
If flame heat is used, be sure gear is heated uniformly around circumference. Do
not overheat. Overheating may also destroy original heat treatment of gear.
c.
Heat new ring gear (11) to 300°F (148°C) using either heated oil, oven heat, or flame heat.
d.
Turn gear so side with chamfer is toward engine with flywheel installed.
e.
Install ring gear (11) against shoulder flywheel.
