MAINTENANCE
INSPECTING AND ADJUSTING THE
COMPRESSOR BELT (AC)
WARNING
• Stop the engine and allow the machine to
cool down before performing
maintenance.
· The engine, muffler, radiator, hydraulic
lines, sliding parts and many other parts
of the machine are hot immediately after
the engine is stopped. Touching these
parts will cause burns.
• Be sure to secure the rear door or radiator
before working the inside.
IMPORTANT: Do not let any oil or grease
get on the belt. It will cause the belt to
slip, decrease the cooling capacity or
shorten the service life of the air
conditioner.
If the belt is too slack, it will slip and vibrate,
resulting in decreased cooling capacity. The
service life of the air conditioner also will be
shortened. Adjust the belt tension to the
standard value (approximately 8 mm or 0.3
in).
Inspection
1. Open the rear door and radiator.
2. Press on the center of the belt (1) with a
finger. The belt’s tension is normal if it
bends about 8 mm (0.3 in) when pressed
with a force of about 98 N (22 lbf).
Adjustment
If the belt’s tension is not normal, adjust it
with the adjust bolt (3).
1. Loosen the lock nut (4).
· Tighten: Clockwise
· Loosen: Counterclockwise
2. Tighten each lock nut (4) after adjustment.
Note:
When replacing with a new belt, run
the engine at low idle speed for about 3 to 5
minutes to break in the new belt, before
adjusting the tension.
Replacing
Replace the belt in the following cases:
· There are cuts or cracks.
· The belt is worn and touches the bottom of
the V groove in the pulley.
· The belt stretched too loose to be
adjusted.
AFTER THE INITIAL 50 HOURS (ONLY FOR NEW MACHINES)
