Servicing the Engine Cooling
System
Service Interval:
Every 100 hours—Inspect the cooling
system hoses.
Every 2 years—Flush the cooling
system and replace fluid.
Remove debris and chaff from the engine
compartment, oil cooler and radiator daily.
Clean
more frequently in dusty and dirty conditions, if required.
1. Turn the engine off and raise the hood. Clean the
engine area thoroughly of all debris.
2. Rotate the latches (Figure 77) securing the oil cooler
to the frame.

3. Pivot the oil cooler rearward. Clean both sides of
the oil cooler and radiator area thoroughly with
compressed air. Start from the fan side and blow
the debris out towards the back. Then clean from
the back side and blow towards the front. Repeat
procedure several times until all chaff and debris is
removed.
Important:
Cleaning the radiator or oil cooler
with water can promote premature corrosion
and damage to components.
4. Pivot the oil cooler back into position. Secure it to
the frame with the latches and close the hood.
Brake Maintenance
Adjusting the Service Brakes
Adjust the service brakes when there is more than 1 inch
(25 mm) of “free travel” of the brake pedal, or when the
brakes do not work effectively. Free travel is the distance
the brake pedal moves before braking resistance is felt.
1. Disengage the locking latch from the brake pedals so
that both pedals work independently of each other.
2. To reduce free travel of the brake pedals, adjust the
brake cables as follows:
A. Loosen the front nut on the threaded end of the
brake cable.
Note:
To allow easier access to the adjusting
nuts, the spring may be unhooked and removed.

B. Tighten the rear nut until the brake pedals have
1/2 to 1 inch (13 to 25 mm) of free travel.
C. Repeat the procedure on the other brake cable.
D. Tighten the front nuts after the brakes are
adjusted correctly.
E. Reinstall the springs, if removed.
Important:
Adjusting the brake tension too
tight will decrease the life of the friction pad
material.
