Fuel Filter
The fuel filter removes contaminants from the fuel as it
enters the engine for combustion. Over time the filter
can become plugged and cause the engine to lose
power, run roughly or fail to start. The fuel filter should
be changed every 500 hours or more often if needed
to prevent these conditions from occurring.
To change the fuel filter: (fig. 4-38)
1.
Clean the outside of the filter assembly thoroughly
to reduce the chances of contaminants being
introduced into the fuel system.
2.
Twist the water separator catch bowl (A) counter
clockwise (when viewed from the bottom) and
remove it from the assembly.
3.
Twist the upper lock ring (B) counter clockwise
(when viewed from the bottom) and remove it from
the assembly.
4.
Slide the filter (C) downward to remove it. Note the
position of the raised tabs on the upper portion of
the filter to simplify reassembly.
5.
Install the new filter element into the assembly by
reversing steps 2-4.
Water Separator
The water separator (item A, fig. 4-38) removes water
from the fuel supply as the engine runs. Drain the
water separator daily to maintain proper function.
To drain the water separator:
1.
Loosen the black screw on the bottom of the
separator.
2.
Re-tighten the screw after the water has been
drained from the catch bowl.
Belt Removal & Installation
To remove the belt:
1.
Shut the machine down as described in section
5.13 of the operations manual.
2.
Remove the cover plate from the top of the fan
shroud (fig. 4-39, item A).
3.
Insert a 3/8” drive ratchet into the square hole
found on the end of the belt tension arm and rotate
it downward away from the belt as shown, to
release pressure on the belt and allow for removal
(fig. 4-40).
4.
With the tension arm held away from the belt
(ste
p 3
