Inspecting and Adjusting the Fan
Belt
WARNING
Stop the engine and allow the machine
to cool before performing inspection and
maintenance.
The engine, muffler, radiator, hydraulic
lines, sliding parts and many other
parts of the machine are hot directly
after the engine is stopped. Touching
these parts will cause burns.
Inspection
1. Open the rear door.
2. Remove the bolts (a) and open the radiator
(b).
3. Press the fan belt midway between the
fan pulley (2) and alternator pulley (3) and
check the tension (about 98N or 22 lbs.).
The slack (A) should be about 7 to 10 mm
(0.28 to 0.4 in.).
4. Inspect the fan belt (4) and replace it if:
• there are cuts or cracks.
• the belt is worn and touches the bottom
of the V groove in the pulley.
• the belt stretches and cannot be
adjusted.
Adjustment
1. Loosen the locking nuts (6).
2. Turn the adjusting bolt (5) and adjust the
fan belt (4).
• Tighten: Clockwise
• Loosen: Counterclockwise
3. Tighten the locking nuts (6).
Note: When replacing with a new belt (new
belt slack: 5 to 8 mm), run the engine at low
idle speed for about three to five minutes to
break in the new belt, before adjusting the
tension.
