DRIVE BELTS

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.

3.

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.

4.

Tighten the lock nut.
