An excessively loose or tight belt could cause an
improperly charged battery, malfunction of the alter-
nator or air compressor. Always keep belts adjusted
to the proper tension.
CAUTION
• Prevent the belt from any contact with oil or
grease during check and adjustment. If
soiled with oil or grease, the belts will slip
and this will shorten their service life.
• If a belt needs to be replaced owing to dam-
age, replace 3 belts at the same time.
1 Check
1. Fully set the parking brake and block the wheels
with chocks to prevent the vehicle from moving.
Then tilt the cab. P. 12-6
2. Press the belt with an approximately 98 N (22
lbs., 10 kgf) force at the point midway between
the pulleys, and measure the amount of deflec-
tion.
3. If the deflection is not as specified below, the
tension of the belt must be adjusted.
