1 Generator Test Hole
1. If test hole is not accessible, disassemble generator and
make tests listed in "OVERHAUL" section.
C. Overcharged Battery
1. To determine battery condition, refer to Battery
Section of Section 6D.
2. Connect a voltmeter from generator No. 2 terminal
to ground. If reading is zero, No. 2 lead circuit is open.
3. If battery and No. 2 lead circuit check good, but an
obvious overcharge condition exists as evidenced by excessive
battery water usage, proceed to "Disassembly" section of
"GENERATOR OVERHAUL", and check field winding for
grounds and shorts. If defective replace rotor, and test
regulator with an approved regulator tester.
Generator Tester
-
Many testers are available to check
the generator. They provide a quick on-car test, and can save
time over conventional diagnostic methods. Consult
manufacturer's instructions for usage.
ON-CAR SERVICE
The generator does not require periodic lubrication. The
rotor shaft is mounted on ball bearings at the drive end and
roller bearings at the slip ring end, and each contains a
permanent grease supply. At periodic intervals, check
mounting bolts for tightness and adjust belt tension.
C A U TI 0 N : When adjusting belt tension, apply
pressure at center ofgenerator, never against either
end frame (see Engine Cooling Section).
Remove From Car
1. Disconnect negative battery terminal at battery.
CAUTION: Failure to observe this step may
result in an injury from hot battery lead at
generator.
2. Remove two terminal plug and battery leads on back
of generator.
3. Loosen adjusting bolts (see Fig. 6D-22A through 6D-
22s for generator mounting).
4. Remove generator drive belt.
5. Remove thru bolt which retains generator.
6. Remove generator from car.

Install In Car
1. If removed from car, install generator to mounting
bracket with bolts, washers and nuts. Do not tighten.
2. Install generator drive belt.
3. Tighten belt to the specified belt tension. See Engine
Cooling Section for proper belt tensioning procedures.
4. Tighten bolts to 30 lb. ft., except bolt at sliding slots
on brackets which is 20 lb. ft.
5. Install generator terminal plug and battery leads to
generator.
6. Connect negative battery terminal.
CA UTI 0 N: Take care not to reverse polarity.
OVERHAUL
To repair the generator, observe the following
procedure:
DISASSEMBLY
To disassemble the generator, take out the four thru-
bolts, and separate the drive end frame and rotor assembly
from the stator assembly by prying apart with a screwdriver
at the stator slot. A scribe mark will help locate the parts in
