MAINTENANCE
INSPECTING AND ADJUSTING THE
V-BELT
• 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.
• Before performing maintenance on top
of the work bench, clean the footing and
observe the following precautions to
prevent falling.
· Do not spill oil or grease.
· Do not leave tools scattered around.
· Watch your step when walking.
• Never jump down from the machine or
the work bench. When getting on or off
the machine or work bench, use the
steps, handrails or work bench to
support your body. Your weight should
be evenly distributed among the three
contact points (one hand and two feet
or two hands and one foot).
• Do not stand on the dozer blade and
perform maintenance work. Doing so is
dangerous because of the unsteady
foothold. Use the work bench.
IMPORTANT: The loose belts could result
in bad battery charge, overheat of engine
or early wear of belt. Too tight belts could
damage the water pump or bearing and
belt used to drive the alternator.
IMPORTANT: Do not let any oil or grease
get on the belt.
AFTER THE INITIAL 50 HOURS (ONLY FOR NEW MACHINES)
Inspection
1. Open the engine hood.
2. Press the fan belt (1) at the midpoint
between the fan pulley (2) and alternator
pulley (3) to check the tension (approx. 98
N or 22 lbf).
The slack (A) should be 6.6 to 7.4 mm
(0.26 to 0.29 in).
3. Inspect the V-belt (4) and replace if it is as
follows.
· 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.
Adjustment
1. Loosen the bolt (5) and locking nut (4).
2. Turn the adjustment bolt (6) to move the
alternator (7) and to adjust the tension of
the fan belt (1).
· Tighten: Clockwise
· Loosen: Counterclockwise
