INSPECTION AND REPAIR OF
ALTERNATOR
Rotor
1. INSPECT ROTOR FOR OPEN CIRCUIT
Using an ohmmeter, check that there is continuity between the slip
rings.
Standard resistance (Cold): 2.8 ± 3.0W
If there is no continuity replace the rotor.4. REMOVE PULLEY
(a) Hold SST(A) with a torque wrench, and tighten SST (B)
clockwise to the specified torque.
SST 09820±63010
Torque: 400 kg±cm (29 ft±Ib, 39 N±m)
(b) Check that SST (A) is secured to the rotor shaft.
(b) Using SST, remove the rectifier end frame.
SST 09286±46011
6. REMOVE ROTOR FROM DRIVE END FRAME5. REMOVE RECTIFIER END FRAME
(a) Remove the four nuts.

3. INSPECT SLIP RINGS
(a) Check that the slip rings are not rough or scored.
If rough or scored, replace the rotor.
(b) Using calipers, measure the slip ring diameter.
Standard diameter. 14.2 ±14.4 mm
(0.559 ± 0.567 in.)
Minimum diameter 12.8 mm (0.504 in.)
If the diameter is less than minimum, replace the rotor.
Brushes
1. INSPECT EXPOSED BRUSH LENGTH
Using a scale, measure the exposed brush length.
Standard exposed length: 10.5 mm (0.413 in,)
Minimum exposed length: 1 .5 mm (0.069 in.)
If the exposed length is less than minimum, replace the
brushes.
Stator
1. INSPECT STATOR FOR OPEN CIRCUIT
Using an ohmmeter, check that there is continuity between
the coil leads.
If there is no continuity, replace the drive end frame assem-
bly.2. INSPECT ROTOR FOR GROUND
Using an ohmmeter, check that there is no continuity
between the slip ring and rotor.
If there is continuity, replace the rotor.
2. INSPECT STATOR FOR GROUND
Using an ohmmeter, check that there is no continuity be-
tween the coil lead and drive end frame.
If there is continuity, replace the drive end frame assembly.

Rectifiers (Rectifier Holder)
1. INSPECT POSITIVE RECTIFIER
(a) Connect the ohmmeter positive (+) probe to each rectifier
terminal and the negative (±) probe to the positive (+) ter-
minal, and check that there is no continuity.
(b) Reverse the ohmmeter probes, and check that there is con-
tinuity.
If continuity is not as specified, replace the rectifier holder.
2. INSPECT NEGATIVE RECTIFIER
(a) Connect the ohmmeter positive (+) probe to each rectifier
terminal and the negative (±) probe to each negative (±)
terminal, check that there is continuity.
(b) Reverse the ohmmeter probes, and checK that there is no
continuity.
If continuity is not as specified, replace the rectifier holder. (c) Solder the brush wire to the brush holder at specified
exposed length.
Exposed length: 10.5 mm (a.413 in.)
(d) Check that the brush moves smoothly in the brush
holder.
(e) Cut off the excess wire.
(f) Apply insulation paint to the soldered point. 2. IF NECESSARY, REPLACE BRUSHES
(a) Unsolder and remove the brush and spring.
(b) Run the wire of a new brush through the hole in the
brush holder, and insert the spring and brush into the
brush holder.
Bearings
1. INSPECT FRONT BEARING
Check that the bearing is not rough or worn.
± CHARGING SYSTEMAlternatorCH±10

2. IF NECESSARY, REPLACE FRONT BEARING
(a) Remove the four screws, bearing retainer and bearing.
(c) Using SST and a press, press in a new bearing.
SST 09608±20012 (09608±00030)
3. INSPECT REAR BEARING
Check that the bearing is not rough or worn.(b) Using a socket wrench and press, press out the bear-
ing.
(d) Install the bearing retainer with the four screws.
