Fan Belt Adjustment
The fan (alternator) drive belt should be checked daily for
tension and wear. The drive belt should be replaced
promptly when fraying of the belt cords or cracks in the
rubber are observed. Failure to replace the drive belt
could lead to slippage or complete failure, causing the
engine to over heat and lead to extensive repairs.
To Adjust the Fan Belt:
1 Park the loader on a level surface, lower the boom
arms, engage the parking brake and shut off the engine.
2 Access the engine compartment by opening the rear
door and lifting the engine cover. (fig. C5000)
3 Locate the drive belt. Fig. C5188 shows the drive
belt without the radiator obstructing the view.
4 Check the drive belt tension midway between the
alternator and crankshaft drive pulley. (fig. C5188)
Correct tension is 3 / 8 ~ 1 / 2’’ deflection @ 22 lbs force
(10 ~ 12mm deflection @ 98 newtons force).
Fan Belt Replacement:
1 Loosen the bolt on the alternator and allow the belt
tension to loosen off. (fig. C5185)
2 Remove the bolts retaining the fan guard to the radia-
tor shroud.
3 Pull the drive belt off the alternator pulley, crankshaft
pulley and remove from around the fan.
4 Replace in reverse order and adjust belt tension as
described above.
