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 turn-
ing crankshaft two turns or more, re-adjust to the specified value to avoid variation in deflection
between pulleys.
Belt Deflection
*: When engine is cold.
Tension Adjustment
BBS002O8
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.
Do not allow oil or engine coolant to get on the belt.
Do not twist or bend the belt strongly.
1. Remove front fender protector (RH). Refer to EI-14, "
