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.

INDEX FOR DTCPFP:00024
DTC No. Index (AUTO DRIVE POS.)BIS0016L
NOTE:

The displays of CAN communication and detent switch display error detecting condition from memory
erase to the present on “TIME”.
–If error is detected in the past and present error is detected, “CRNT” is displayed.
–If error is detected in the past and present error is not detected, “PAST” is displayed.
–If error has never been detected, nothing is displayed on “TIME”.

Any items other than CAN communication and detent switch count error detection frequency occurred
after erase history to “1-127”.
–If error was detected in the past, error detection frequency from memory erase to the present is displayed
on “TIME”.
–If error has never been detected, nothing is displayed on “TIME”.
–Can clear the detected memory.
Normal: Clear memory in normal condition, history is erased and nothing is displayed on “TIME”.
Error: Clear memory in error condition, error is detected again and “1” is displayed on “TIME”.

PRECAUTIONS

PRECAUTIONSPFP:00001
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
BIS00129
The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, used along
with a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain
types of collision. Information necessary to service the system safely is included in the SRS and SB section of
this Service Manual.
WARNING:

To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death
in the event of a collision which would result in air bag inflation, all maintenance must be per-
formed by an authorized NISSAN/INFINITI dealer.

Improper maintenance, including incorrect removal and installation of the SRS, can lead to per-
sonal injury caused by unintentional activation of the system. For removal of Spiral Cable and Air
Bag Module, see the SRS section.

Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or
harness connectors.
Service NoticeBIS0012A

When removing or installing various parts, place a cloth or padding onto the vehicle body to prevent
scratches.

Handle trim, molding instruments, grille, etc. carefully during removing or installing. Be careful not to oil or
damage them.

Apply sealing compound where necessary when installing parts.

When applying sealing compound, be careful that the sealing compound does not protrude from parts.

When replacing any metal parts (for example body outer panel, member, etc.), be sure to take rust pre-
vention measures.
Precautions BIS0012B

When removing or disassembling any part, be careful not to damage or deform it. Protect parts, which
may get in the way with cloth.

When removing parts with a screwdriver or other tool, protect parts by wrapping tools with vinyl or tape.

Keep removed parts protected with cloth.

If a clip is deformed or damaged, replace it.

If an unreusable part is removed, replace it with a new one.

Tighten bolts and nuts firmly to the specified torque.

After re-assembly has been completed, make sure each part functions correctly.

Remove stains in the following way.
Water-soluble stains:
Dip a soft cloth in warm water, and then squeeze it tightly. After wiping the stain, wipe with a soft dry cloth.
Oil stain:
Dissolve a synthetic detergent in warm water (density of 2 to 3% or less), dip the cloth, then clean off the stain
with the cloth. Next, dip the cloth in fresh water and squeeze it tightly. Then clean off the detergent completely.
Then wipe the area with a soft dry cloth.

Do not use any organic solvent, such as thinner or benzine.
