Checking the Rear Wheel

Toe-In

After every 800 operating hours or annually, check
the rear wheel toe-in.
1. Measure the center-to-center distance (at axle
height) at the front and rear of the steering
tires. The front measurement must be 1/4 inch
(6 mm) less than the rear measurement.
2. To adjust, loosen the clamps at both ends of
the tie rods.
3. Rotate the tie rod end to move the front of the
tire inward or outward.
4. Tighten the tie rod clamps when the adjustment
is correct.

Maintenance

Servicing the Engine Cooling

System

Remove debris from the oil cooler and radiator
daily. Clean them more frequently in dirty
conditions.
1. Turn the engine off and raise the hood. Clean
the engine area thoroughly of all debris.
2. Remove the knobs (Figure 61) securing the oil
cooler to the frame.

3. Pivot the oil cooler rearward. Clean both sides
of the oil cooler and radiator area (Figure 62)
thoroughly with compressed air.
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 knobs 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,
tighten the brakes:
A. Loosen the front nut on the threaded end
of the brake cable.
B. Tighten the rear nut to move the cable
backward until the brake pedals have 1/2
to 1 inch (13 to 25 mm) of free travel.
C. Tighten the front nuts after the brakes are
adjusted correctly.
