DISASSEMBLY
Rear Cover
1. Remove through-bolt (4).
2. Remove rear cover.
NOTE:
Rear cover may be hard to remove because a ring is used to
lock outer race of rear bearing. To facilitate removal of rear
cover, heat just bearing box section with a 200 W soldering iron
until the temperature increases by about 30 °C.
CAUTION:
Never use a heat gun, as it can damage diode assembly.

Front Cover (For LR1110-713B)
1. Set rotor to the vise.
CAUTION:

Be careful not to damage the rotor.

Use copper plate or thick cloth for rotor in the vise.
2. Remove pulley cap, using suitable tool.
3. Remove alternator pulley, using alternator pulley adaptor [SST].
INSPECTION
Rotor Check
1. Resistance test

Not within the specified values... Replace rotor.
2. Insulator test

Continuity exists... Replace rotor.
3. Check slip ring for wear.

Not within the specified values... Replace rotor.
Brush Check
1. Check smooth movement of brush.

Not smooth... Check brush holder and clean.
2. Check brush for wear.

Replace brush if it is worn down to the limit line.

Pulley Check (With Clutch Type)
1. Check for locking (Outer ring is turned counterclockwise when
viewed from the rear).

If it rotates in both directions... Replace pulley.
2. Check for dragging (Outer ring is turned clockwise when viewed
from the rear).

If it locks or unusual resistance is felt... Replace pulley.
Stator Check
1. Continuity test

No continuity... Replace stator.
2. Ground test

Continuity exists... Replace stator.
ASSEMBLY
Ring Fitting In Rear Bearing
Fix ring into groove in rear bearing so that it is as close to the adja-
cent area as possible.
CAUTION:
Do not reuse rear bearing after removal.

TROUBLE DIAGNOSIS

Trouble Diagnosis with CONSULT-IIBHS0004A
DIAGNOSTIC PROCEDURE 2
CAUTION:

If CONSULT-II is used with no connection of CONSULT-II CONVERTER, malfunctions might be
detected in self-diagnosis depending on control unit which carry out CAN communication.

The display of self-diagnostic results in “SELF-DIAG [CURRENT]”, “SELF-DIAG [PAST]” and
“TROUBLE DIAG RECORD” screens of CONSULT-II is limited to 3 items at once. Scroll for 4 or
more screens when checking.
1. Touch “SELF-DIAG [CURRENT]”.
2. Diagnostic code is displayed on “SELF-DIAG [CURRENT]”.
a. If no malfunction is detected on “SELF-DIAG [CURRENT]” even
though malfunction is detected in “SRS Operation Check”,
check the battery voltage. If the battery voltage is less than 9 V,
charge or replace the battery. Refer to SRS-22, "
DIAGNOSTIC
PROCEDURE 3" . If the battery voltage is OK, refer to SRS-24,
"DIAGNOSTIC PROCEDURE 4 (CONTINUED FROM DIAG-
NOSTIC PROCEDURE 2)" . diagnose the following cases:

Self-diagnostic result “SELF-DIAG [PAST]” (previously stored in
the memory) might not be erased after repair.

The SRS system malfunctions intermittently.

Refer to SRS-22, "DIAGNOSTIC
PROCEDURE 3" after charging the
battery.

Self-diagnostic result “SELF-DIAG
[PAST]” (previously stored in the
memory) might not be erased after
repair.

Intermittent malfunction has been
detected in the past.

Refer to SRS-24, "DIAGNOSTIC
PROCEDURE 4 (CONTINUED

2. Touch “TROUBLE DIAG RECORD”.
NOTE:
With “TROUBLE DIAG RECORD”, diagnosis results previously
erased by a reset operation can be displayed.
3. Diagnostic code is displayed on “TROUBLE DIAG RECORD”.
4. Touch “PRINT”.
5. Compare diagnostic codes toSRS-25, "
CONSULT-II Diagnostic
Code Chart (“SELF-DIAG [PAST]” or “TROUBLE DIAG
RECORD”)" .
6. Touch “BACK” key of CONSULT-II until “SELECT SYSTEM”
appears.
7. Turn ignition switch OFF, then turn off and disconnect CON-
SULT-II, and both battery cables.
8. Repair the system as outlined by the “Repair order” in “Intermit-
tent Malfunction Diagnostic Code Chart”, that corresponds to the
self-diagnostic result. For replacement procedure of component parts, refer to the Removal and Installa-
tion procedure for the appropriate component.
9. Refer to SRS-22, "
DIAGNOSTIC PROCEDURE 3" , for final checking.
