MAINTENANCE
SERVICE PROCEDURE
CLEAN, CHECK AIR CONDITIONER CONDENSER FINS
If the air conditioner fins become clogged, clean and inspect.
1. Open the engine side cover on the right side of the machine.
2.
Use compressed air to blow off all the mud, dirt, and leaves
clogging fins (1).
ADJUST IDLER CLEARANCE
The idler moves to the front and rear under external force. When
this happens, guide plate (2) becomes worn. It guide plate (2)
becomes worn, the idler will slip to the side or tilt at an angle. This
will lead to the track shoe slipping or cause uneven wear, so adjust
as follows.
ADJUSTMENT
1.
Travel on flat ground for 1 to 2 m (39.4 to 78.8 in), then remove
cover (3) (both in and out of) on the side face of the idler.
2. Measure clearance A (4 places: left, right, inside, outside)
between the track frame and guide plate.
3.
If clearance A is more than 3 mm (0.118 in), loosen bolt (1), and
remove the shim to adjust the clearance to a maximum of 0.5
to 1 mm (0.020 to 0.039 in) on each side.
REMARK
The thickness of 1 shim is 1.0 mm (0.039 in).
