Routine Service and Maintenance

10. Check both track assemblies for:
a. The proper tension. Too little or too much tension can cause premature track wear and
travel motor damage.
b. Make sure that the tracks are not worn or damaged.
c. Make sure that the nylon guide block is centered within the track and is guiding the
track properly.
d. Make sure the Track Adjustment Guide Bushings (located in Frame) are not worn or
damaged.
e. Check for loose or missing fasteners.
f. Inspect for any loose or missing bolts or fasteners.
g. Tighten or replace any missing bolts or fasteners before operating the machine.
11. Check for proper track tension.
a. Raise the machine off the ground and support it using a device capable of safely
supporting 4000 lbs. (1820 kg) See Figure 4–11 for suggested location of the support
devices.
b. Tilt the bucket downwards until the cutting edge is touching the ground. See Figure
4–11.
c. Lower the loader arm assembly, pushing the front of the machine upwards. Continue
raising the machine until the rear drive sprocket is off the ground. Shut off the engine.
Keeps hands and ngers from under the track and track guide rollers.
d. Measure the gap between the bottom of the center bogey guide roller (Item 1, Figure
4–11) and the track. The proper tension will be about a 1/4” - 3/8” (6 mm - 10 mm)
deection.
e. If an adjustment is needed, remove tension lock plate (see Item 3, Figure 4-9) then rotate
the track tension adjustment nut (Item 2, Figure 4–11) until the proper track deection
measurement is achieved.
f. With the tracks still off the ground, start the engine and rotate just the track being
adjusted three or four times in both forward and reverse. Shut off the engine after
rotating the track.
g. Remeasure the deection dimension. If good, install tension lock plate and bolt.
h. Check the other track for the correct tension measurement. If needed, repeat Steps 10e -
10g.
i. Lower the machine onto the ground and remove the support devices.
12. Inspect the Track Widening Stop Bolts for:
a. Signs of damage or wear:
- Fully retract the tracks and make sure that the stop bolts (Item 1, Figure 4–12) are not
bent or damaged.
- If the bolt shows any signs of damage, replace the bolt.
- Extend the tracks to make sure that the track assemblies move freely.
