ALTERNATOR PULLEY INSPECTION (QR ENGINE MODELS)
One-Way Clutch Pulley Check
Fix rotor with inserting a suitable tool rolled with a cloth.
CAUTION:
Be careful not to damage the rotor.
1. Check for locking. (Outer ring is turned clockwise when viewed
from the front.)

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

If it locks or unusual resistance is felt... Replace pulley.

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 LR1110-713V)
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

d. Remove A/T fluid level gauge and wipe clean lint-free paper.
CAUTION:
When wiping away the A/T fluid level gauge, always use lint-free paper, not cloth one.
e. Re-insert A/T fluid level gauge into charging pipe as far as it will go.
CAUTION:
To check fluid level, insert the A/T fluid level gauge until the cap contacts the end of the A/T fluid
charging pipe, with the A/T fluid level gauge reversed from the normal attachment conditions.
f. Remove A/T fluid level gauge and note reading. If reading is at low side of range, add fluid to the A/T fluid
charging pipe.
CAUTION:
Do not overfill.
4. Drive vehicle for approximately 5 minutes in urban areas.
5. Re-check fluid level at fluid temperatures of 50 to 80°C (122 to 176°F) using “HOT” range on A/T fluid
level gauge.
CAUTION:

When wiping away the A/T fluid level gauge, always use lint-free paper, not cloth one.

To check fluid level, insert the A/T fluid level gauge until the cap contacts the end of the A/T fluid
charging pipe, with the A/T fluid level gauge reversed from the normal attachment conditions.
6. Check fluid condition.

If fluid is very dark or smells burned, refer to AT section for
checking operation of A/T. Flush cooling system after repair of
A/T.

If A/T fluid contains frictional material (clutches, bands, etc.),
replace radiator and flush cooler line using cleaning solvent
and compressed air after repair of A/T. Refer to CO-12,
"RADIATOR" , CO-15, "RADIATOR (ALUMINUM TYPE)" .
7. Install the removed A/T fluid level gauge in the A/T fluid charging
pipe.
Changing A/T FluidELS000BW
1. Warm up A/T fluid.
2. Stop engine.
3. Drain A/T fluid from drain plug and refill with new A/T fluid.
Always refill same volume with drained fluid.
4. Run engine at idle speed for five minutes.
5. Check fluid level and condition. Refer to MA-40, "
Checking A/T Fluid" . If fluid is still dirty, repeat steps 2
through 5.
Checking Transfer OilELS000BT
Check for oil leakage and oil level.
(For details, refer to TF-10, "
Inspection" .)
