INSPECTING AND ADJUSTING THE FAN BELT
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: 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.

22 lbf).
The slack (A) should be 7 to 9 mm (0.28 to
0.35 in).
