Routine Service and Maintenance
4.8
NOTE:
Extremely dusty or dirty working conditions may require more frequent service/
replacement.
4. 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.
5. Check for loose or missing fasteners.
a. Inspect for any loose or missing bolts or fasteners.
b. Tighten or replace any missing bolts or fasteners before operating the machine.
6. Check for proper track tension.
a.
Raise the machine off the ground and support it using a device capable of safely
supporting 4000 lbs. See
Figure 4–9
for suggested location of the support devices, as an
example, place a concrete or solid wooden block under the operators platform and solid
supports under the bucket.
b. Tilt the bucket downwards until the cutting edge is touching the ground. See
Figure 4–9
.
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 fingers from under the track and track guide rollers.
d. Measure the gap between the bottom of the center bogey guide roller (Item 1,
Figure
4–9
) and the track. The proper tension will be about a 1/4” - 3/8” deflection.
e. If an adjustment is needed, remove the adjustment nut lock plate and rotate the tension
adjustment nut (Item 2,
Figure 4–9
) until the proper track deflection measurement is
achieved. Reinstall and secure the adjustment nut lockplate.
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.
Re - measure the deflection dimension.
h. Check the other track for the correct tension measurement. If needed, repeat Steps 6e -
6g.
i. Lower the machine onto the ground.
