CheckingINFOID:0000000001381384
 Inspection should be done only when engine is cold or over 30
minutes after the engine is stopped.
 Visually check belts for wear, damage, and cracks on inside and
edges.
 Turn crankshaft pulley two time clockwise, and make sure tension on all pulleys is equal before doing the
test.
 When measuring deflection, apply 98 N (10 kg, 22 lb) at the ( ) marked point.
 Measure the belt tension and frequency with acoustic tension gauge (commercial service tool) at the ( )
marked point.
CAUTION:
 When the tension and frequency are measured, the acoustic tension gauge should be used.
 When checking 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.
Tension AdjustmentINFOID:0000000001381385
CAUTION:
 When belt is replaced with new one, adjust belt tension to the value for “New belt”, because new belt
will not fully seat in the pulley groove.
 When tension of the belt being used exceeds “Limit”, adjust it to the value for “After adjusted”.
 When installing a belt, make sure it is correctly engaged with the pulley groove.
 Never allow oil or engine coolant to get on the belt.
 Never twist or bend the belt strongly.
1. Loosen the idler pulley lock nut (A) from the tightening position
with the specified torque by 45 degrees.

CAUTION:
 When the lock nut is loosened excessively, the idler pulley tilts and the correct tension adjust-
ment cannot be performed. Never loosen it excessively (more than 45 degrees).
 Put a matching mark on the lock nut, and check turning angle with a protractor. Never visually
check the tightening angle.
2. Adjust the belt tension by turning the adjusting bolt.
CAUTION:
 When checking 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 deflec-
tion between pulleys.
 When the tension adjustment is performed, the lock nut should be in the condition at step“2”. If
the tension adjustment is performed when the lock nut is loosened more than the standard, the
idler pulley tilts and the correct tension adjustment cannot be performed.
3. Tighten the idler pulley lock nut.
Removal and InstallationINFOID:0000000001381386
REMOVAL
1. Loosen the idler pulley lock nut (A), and then adjust the belt ten-
sion by turning the adjusting bolt (B).
2. Remove drive belt.
INSTALLATION
1. Pull the idler pulley in the loosening direction, and then tempo-
rarily tighten the idler pulley lock nut (A) to the following torque.
NOTE:
Do not move the lock nut from the tightened position. Proceed to step “2”.
2. Install the drive belt to each pulley.
CAUTION:
 Make sure that there is no oil, grease, or coolant, etc. in pulley grooves.
 Make sure that the belt is securely inside the groove on each pulley.
3. Adjust drive belt tension by turning the adjusting bolt. Refer to EM-15, "
Tension Adjustment".

Checking Drive BeltsINFOID:0000000001337777
WARNING:
Be sure to perform this step when the engine is stopped.
 Make sure that the indicator (notch on fixed side) of drive belt auto-tensioner is within the possible use range
(A).
NOTE:
 Check the drive belt auto-tensioner indication when the engine is cold.
 When new drive belt is installed, the indicator (notch on fixed side) should be within the range (B).
 Visually check entire drive belt for wear, damage or cracks.
 If the indicator (notch on fixed side) is out of the possible use range or belt is damaged, replace drive belt.
Tension AdjustmentINFOID:0000000001337778
Belt tension is not necessary, as it is automatically adjusted by drive belt auto-tensioner.
Removal and InstallationINFOID:0000000001337779
REMOVAL
1. Hold the hexagonal part (A) of drive belt auto-tensioner (1) with
a wrench securely. Then move the wrench handle in the direc-
tion of arrow (loosening direction of tensioner).
CAUTION:
Never place hand in a location where pinching may occur if
the holding tool accidentally comes off.
2. Insert a rod such as short-length screwdriver approximately 6
mm (0.24 in) in diameter into the hole (B) of the retaining boss to
fix drive belt auto-tensioner.
