4. REMOVE GENERATOR ROTOR ASSY
(a) Remove the generator washer and generator rotor.
5. INSPECT GENERATOR BRUSH HOLDER ASSY
(a) Inspect the length.
(1) Using vernier calipers, measure the exposed brush
length.
Standard exposed brush length: 10.5 mm (0.413 in.)
Minimum exposed brush length: 4.5 mm (0.177 in.)
If the exposed brush length is less than minimum, replace the
generator brush holder.
6. INSPECT GENERATOR ROTOR ASSY
(a) Check that the bearing is not rough or worn.
If necessary, replace the generator rotor.
(b) Inspect the resistance.
(1) Using an ohmmeter, measure the resistance be-
tween the slip rings.
Resistance: 2.3 to 2.7W at 20
C (68
F)
If the resistance is not as specified, replace the generator rotor.
(c) Check the continuity.
(1) Using an ohmmeter, check that there is no continu-
ity between the slip ring and rotor core.
If there is continuity, replace the generator rotor.
(d) Check the appearance.
(1) Check that the slip rings are not rough or scored.
If rough or scored, replace the generator rotor.

(e) Inspect the diameter.
(1) Using vernier calipers, measure the slip ring diame-
ter.
Standard diameter:
14.2 to 14.4 mm (0.559 to 0.567 in.)
Minimum diameter: 14.0 mm (0.551 in.)
If the diameter is less than minimum, replace the generator ro-
tor.
7. INSTALL GENERATOR ROTOR ASSY
(a) Place the generator drive end frame on the generator
pulley.
(b) Install the generator rotor and generator washer.
8. INSTALL GENERATOR COIL ASSY
(a) Using a deep socket wrench 21 and press, press in the
generator coil carefully.
(b) Tighten the 4 bolts.
Torque: 5.8 NVm (59 kgfVcm, 51 in.Vlbf)
9. INSTALL GENERATOR BRUSH HOLDER ASSY
(a) While pushing the 2 brushes to inside the brush holder,
insert a pin (f1.0 mm (0.039 in.)) into the brush holder
hole.

** These tools can be ordered through the Lexus Approved Dealer Equipment program by calling
1±800±368±6787.
NOTE:
The ªFast Battery Chargersº listed above have been tested and approved by Lexus.
These state±of±the±art ªsmartº chargers were designed to charge batteries at an
accelerated rate, without the possibility of damage. Using non±microprocessor
controlled battery chargers for fast charging purposes can damage the battery.
All vehicles are to be inspected according to the procedures listed below using the
MICROPRO 815 battery tester no more than 48 hours prior to customer vehicle delivery.
PRIOR TO TESTING:
If necessary, remove battery surface charge by turning on high beam headlights for 60
seconds, then let battery voltage recover for one minute.
1. Connect test clamps to battery.
(Display will show four zeros
indicating a good connection).
2. For cold battery (<32
F) or after
charge test, press TEST MODE key
until appropriate test is selected.
3. Input battery stock number.
NOTE:
Stock number must be used for
warranty cases because you cannot
read the warranty code if CCA/CA
rating is input.
4. Press STK#/Code key to start test.
NOTE:
Stock numbers are listed on the
reference card located in the tester's
cover. Stock numbers can also be
referenced on TIS. The TIS listings
will always have up±to±date
information.
Stock number location in TIS:
