MAINTENANCE/PARTS BREAKDOWN
INSPECTION/CLEANING
Periodically inspect the rotor carrier bearing. Replace this
bearing at 10,000 hours of normal operation or sooner if
wear is evident.
Inspect and clean the control box interior, look for loose,
broken, or burned wires and terminals. Use low air pressure
(25 psi max.) to remove dirt and dust from components.

DISASSEMBLY
Should it become necessary to disassemble the stator/rotor
assembly from the engine, use the following as a guide.
1. Properly supporlllift the rear of the engine to allow the
generator to be unbolted from the rear support isolators.
2. Mark, then disconnect the electricalleds that exit the
generator from their connections in the control box. Be
sure to properly mark the connection points the generator
leds connect
to. Make an illustration if needed whether
the generator is to be reinstalled or a replacement is to
be installed. This is to ensure proper reconnection of
electricalleds. Unbolt
the control box and lift it off the
generator.
3. Remove the rear vent cover. Support the generator with a
sling or
fabricated lifting eye. Using a 17mm socket
wrench remove the four bolts that attach the generator
stator
housing assembly to the flywheel housing.
carefully work the stator assembly off the rear bearing
and off and over the rotor assembly.
Remove all dirt, oil, grease and dust build up from the
external surface of the generator. Build·up reduces heat
dissipation and causes the AC generator end to operate at a
higher temperature. This results
in a loss of efficiency and
reduces service life.
4. Support the rotor assembly with a sling and using a
17mm box wrench, unbolt the rotor assembly from the
flywheel.
