Track Tension (PT-100G)
Proper track tension must be maintained for optimal
performance and track/undercarriage life. Running a
track that is too loose may cause the track to misfeed
possibly causing damage to the track and or
undercarriage components. Running a track that is too
tight may cause the track to stretch, create premature
bearing failure, or other preventable damage to the
machine. As a rule, a track should only be tightened to
the point where there is no visible sag. Never tighten
your tracks beyond this point.
Note:
During the first 50 hours of operation the tracks
will "break-in" and will most likely require adjustment.
To check track tension:
(fig. 4-7, 4-8)
1.
Drive the machine forward 5 feet to remove belt
slack from the lower and rearward portions of the
track.
2.
Lay a straight edge along the top of the track
bridging the drive sprocket and front idler wheel.
3.
Apply 90 lbs. of down force to the the track by
either placing weight on top, or by hanging the
weight by using rope or wire, midway between
the drive sprocket and front idler as seen in
figure 4-8.
4.
Measure from the bottom of the straight edge to
the lug surface (top) of the track. The deflection
should measure between 3/4" and 1" (1.9-2.5
cm).
To adjust track tension:
(fig. 4-9)
1.
Loosen the lock nut (A) on the turnbuckle (B)
and adjust by turning the turn buckle itself until
proper tension has been achieved.
2.
Then tighten the turnbuckle lock nut to complete
the procedure.
3.
Repeat the adjustment procedure on the other
side of the machine if necessary.
Planetary Oil Change
(fig. 4-10)
1.
Place the machine on jackstands as described in
jacking prodedure in this chapter.
2.
Orient the perimeter drain plug at the very
bottom of the drive motor, then turn the engine
off and remove the key to avoid accidental start.
3.
Remove the plug and drain the oil into a suitable
catch container. (fig. 4-10) Dispose oil according
to mandates.
4.
Start the machine (make sure all personnel are
clear of the machine), then roll the drive motor
over so that the drain/fill hole is on the very top
of the drive motor. Stop the engine and remove
the key to avoid accidental start.
5.
Fill the planetary with .95qt (.9l) of 75-140
synthetic gear oil, reinstall plug.
6.
Repeat the procedure on the opposite drive
motor.
