REMOVAL
1. Remove engine undercover. Refer to
EXT-39, "FRONT UNDER COVER : Removal and Installation".
2. Remove wheel and tire (RH) using a power tool. Refer to WT-48, "
Removal and Installation".
3. Partially remove the fender protector (RH). Refer to EXT-38, "
Removal and Installation".
4. Loosen the lock nut and then release the belt tension by turning the adjusting bolt.
5. Remove the drive belt.
INSTALLATION
1. Pull the idler pulley in the loosening direction, and then temporarily tighten the lock nut to the following
torque.
NOTE:
Do not move the lock nut from the te mporary tightened position. Go to step 2.
2. Install the drive belt on each pulley. CAUTION:
• Check that there is no engine oil, grease, or engine coolant, etc. in pulley grooves.
• Check that the belt seats securely inside the groove on each pulley.
3. Adjust drive belt tension by turning the adjusting bolt. Refer to EM-17, "
Adjustment".
CAUTION:
• Perform the belt tension adjustment with the lock nut temporarily tightened to the torque specifi-
cation listed in step 1 which preven ts the idler pulley from tilting.
• When checking immediately after in stallation, first adjust it to the specified value. Then, after
turning crankshaft two turns or more, readjust to the specified value to avoid variation in deflec-
tion between pulleys.

4. Tighten the lock nut to final tightening specification.
5. Check that belt tension is within the specification using suitable tool. Refer to
EM-116, "
Drive Belt".
InspectionINFOID:0000000012431695
• Inspection should be done only when engine is cold or over 30
minutes after the engine is stopped.
• Visually check belt for wear, damage, and cracks on inside and edges.
• Turn crankshaft pulley clockwise twice, and check that the tension on all pulleys equalizes before testing.
• When measuring deflection, apply 98.1 N (10 kg, 22 lb) at the ( ) marked point.
• Measure the belt tension and frequency using suitable tool at the ( ) marked point.
CAUTION:
• When checking immediately after installation, first ad just it to the specified value. Then, after turning
crankshaft two turns or more, readjust to the specified value to avoid varia tion in deflection between
pulleys.
AdjustmentINFOID:0000000012431696
CAUTION:
• When belt is replaced with new one, adjust belt te nsion 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, check it is correctly engaged with the pulley groove.
• Do not allow engine oil or engine coolant to get on the belt.
• Do not twist or bend the belt strongly.
1. Partially remove the fender protector (RH) front side clip. Refer to EXT-38, "
Removal and Installation".
2. Loosen lock nut (A) and temporarily set to the following torque.
3. Adjust the belt tension by turning the adjusting bolt. Refer to EM-116, "
Drive Belt".
