DRIVE BELTS

DRIVE BELTSPFP:02117
Checking Drive BeltsBBS004VM
WARNING:
Be sure to perform the following when engine is stopped.
1. Inspect belts for cracks, fraying, wear and oil. If necessary, replace.
2. Inspect drive belt deflection at a point on the belt midway
between pulleys.

Inspection should be done only when engine is cold, or over
30 minutes after engine is stopped.

When measuring deflection, apply 98 N (10 kg, 22 lb) at the
marked point.

Adjust if belt deflection exceeds the limit.
CAUTION:

When checking belt deflection immediately after installa-
tion, first adjust it to the specified value. Then, after turning
crankshaft two turns or more, re-adjust to the specified
value to avoid variation in deflection between pulleys.

Release the tension by loosing lock nut and turning adjust-
ing bolt when adjusting the belt. Tighten once the lock nut
at 4.9 N·m (0.50 Kg-m, 43 in-lb). Then, adjust the belt ten-
sion by loosing lock nut between 45° and 90°.
Belt Deflection
Tension AdjustmentBBS004VN
CAUTION:

When belt is replaced with a new one, adjust it to value for “New belt” to accommodate for insuffi-
cient adaptability with pulley grooves.

When deflection of belt being used exceeds “Limit”, adjust it to value for “After adjustment”.

When checking belt deflection immediately after installation, first adjust it to the specified value.
Then, after turning crankshaft two turns or more, re-adjust to the specified value to avoid variation
in deflection between pulleys.

When installing belt, make sure that it is correctly engaged with pulley groove.

Release the tension by loosing lock nut and turning adjusting nut when adjusting the belt. Tighten
once the lock nut at 4.9 N·m (0.50 Kg-m, 43 in-lb). Then, adjust the belt tension by loosing lock nut
between 45° and 90°.

Keep engine oil, working fluid and engine coolant away from belt.

Do not twist or bend belt excessively.
ALTERNATOR AND A/C COMPRESSOR BELT
1. Remove splash guard (RH).
2. Loosen idler pulley lock nut (A).
3. Release the belt tension on idler pulley by turning adjusting nut
(B).
4. Tighten lock nut (A).
5. Loosen lock nut (A) between 45° and 90°.
6. Adjust tension by turning adjusting nut (B).

For specified belt tension, refer to EM-128, "Checking Drive
Belts" .
7. Tighten lock nut (A).
8. Tighten adjusting nut (B).
POWER STEERING OIL PUMP BELT
1. Remove splash guard (RH).
2. Loosen lock bolt (C).
3. Loosen power steering oil pump mounting bolt (D).

Bolt head (D) is engine rear side.
4. Adjust tension by turning adjusting bolt (E).

For specified belt tension, refer to EM-128, "Checking Drive Belts" .
NOTE:
Adjusting bolt (E) is loosened with counterclockwise rotation.
5. Tighten lock bolt (C).
6. Tighten power steering oil pump mounting bolt (D).
Removal and InstallationBBS004VO
REMOVAL
1. Remove splash guard (RH).
2. Fully loosen each belt by following the guidelines in EM-128, "
Tension Adjustment" . Remove alternator
and A/C compressor belt and then power steering oil pump belt.
CAUTION:
Grease is applied to idler pulley adjusting bolt. Be careful to keep grease away from belt.
INSTALLATION
1. Install each belt to pulley in the reverse order of removal. : 4.9 N·m (0.50 kg-m, 43 in-lb)

CAUTION:

Make sure belt is correctly engaged with the pulley groove.

Make sure that for engine oil, working fluid and engine coolant do not adhere to belt and each
pulley groove.
2. Adjust belt tension. Refer to EM-128, "
Tension Adjustment" .
3. Tighten each nuts and bolts to the specified torque.
4. Make sure that tension of each belt is within the standard. Refer to EM-128, "
