Check the thermostat performance regularly. This can effect the coolant circulation and cause the tractor
to run hot.
4.22 Bleeding the Fuel System
If the tractor is parked for a long period of time or you are replacing the diesel fuel filter element or you
have an empty fuel tank, air could get into the fuel line, which could cause starting problems. R emove the
air as follows:
1.
Open the fuel filter bleed screw.
2.
Work the fuel transfer hand pump up and down until bubble-free diesel starts flowing out from the bleed
screw on the fuel filter.
3.
Tighten the bleed screw on the fuel filter and open the injection pump bleed screw. Work the fuel
transfer hand pump up and down until bubble-free diesel starts flowing out from the bleed screw on the
injector pump.
4.23 Rear Axle Structure and Adjustment
4.23.1 Brake Adjustment
The brake pedal free play should
be 120~130 mm.
When the brake friction lining is worn,
the brake pedal free play will increase and
braking will be less effective. Therefore, the
brake must be adjusted (as shown in
Figure 4–5).
Unscrew the nut and adjust the steering tie rod
and to set the brake pedal free play at 120 – 130
mm. Meke the free play of the right and left
pedals the same. Once the adjustment is made,
tighten the lock the nut.
