(1) Check that the belts are not damaged and are properly
fit into the pulley grooves.
Caution
1. When installing the V-ribbed belt, check that the
V-ribs are properly fit without misalignment.
2. If creaking or slippage is observed, check the
belt for wear, damage, or breakage on the pulley
contact surface, check the pulley for scoring, in
addition to sag inspection.
3. Check that the V-ribbed belt is not resting on the
tension pulley or idler pulley flange.
(2) With belt tension gauge set to the belt midway between
the pulleys as shown in the illustration, check the belt
tension for standard value. Or apply a force of 98 N (22
Ibs.) to the belt to check the deflection for standard value.
