Checking and Adjusting the Track
Tension
Service Interval: After the first 50 hours
Every 100 hours
To check the tension of each track, place 20.4 kg (45
lb) on the track midway between the front road wheel
and the drive wheel. The track should flex no more
than 0.6 to 1 cm (1/4 to 3/8 inch). If it does, adjust the
track tension using the following procedure:

Figure 42
1. Park the machine on a level surface, engage the
parking brake, and lower the hydraulic lift.
2. Shut off the engine and remove the key.
3. Loosen the jam nut on the track tensioning bolt
and the clamp bolts on the tension arm (
Figure
43 ).

4. Torque the tensioning bolt to 32.5 to 40 N∙m (24
to 30 ft-lb) to tighten the track (
Figure 43 ).
5. Ensure that the track deflects less than 0.6 to 1
cm (1/4 to 3/8 inch) when 20.6 kg (45 lb) of force
is applied to the track span. Adjust the torque on
the tensioning bolt as needed.
6. Tighten the jam nut.
7. Tighten the clamp bolts and torque to 102 N∙m
(75 ft-lb).
Replacing the Tracks
When the tracks are badly worn, replace them.
1. Park the machine on a level surface, engage the
parking brake, and lower the hydraulic lift.
2. Shut off the engine and remove the key.
3. Lift and support the side of the unit to be worked
on so that the track is 7.6 to 10 cm (3 to 4
inches) off the ground.
4. Back out the tensioning bolt and jam nut ( Figure
43 ).
5. Loosen the clamp bolts ( Figure 43 ).
6. Push the front road wheel rearward as far as it
can goes (
Figure 44 ).

7. Begin removing the track at the top of the front
road wheel, peeling it off the wheel while rotating
the track forward.
Note:
You may need to remove the front,
outside road wheel. To remove it, remove the
snap ring and cap from the center of the road
wheel (
Figure 45 ). Next remove the bolt and
gasket from the center of the wheel and pull the
wheel off the machine.
