FINAL DRIVE MAINTENANCE
1. Model 905 Chain Adjustment
Figure 32: Chain Adjustment
There is single wheel chain on each side
of your 905 mini skid. This chain is
factory tensioned for correct operation.
However, as your chain wears in, some
adjustment may be required.
In order to tighten your wheel chains
first loosen the four bolts securing the
front axle to the machine body. The
bolts should be loosened only enough to
allow the axle to move forward and
back.
After loosening the bolts adjust the two
axle bolts, shown in Figure 32, to adjust
the chain tension. Note that it is
important to tension each bolt equally in
order to keep the axle square to the
machine. If proper chain tension cannot
be achieved with the axle square, the
drive chains should be replaced. After
chain adjustment tighten the four axle
bolts to secure the front axle.
Chain tension should be checked on a
weekly basis.
2. Model 915 Track Adjustment
Figure 33: Track Tensioner
The track system on your 915 mini skid
does not use any chains, however it is
important to keep your track system
tensioned properly.
Tracks should be tensioned so that a
180lb person standing on one foot in the
center of the track makes the track bend
down approximately 1”.
Track tension can be adjusted through
the track tensioner, shown in Figure 33,
located near the front track roller.
Simply loosen the eight bolts securing
the front axle to the frame, and use a
wrench to tighten the tensioning nut until
desired track tension is achieved.
Tighten the eight axle bolts down again
to secure the front axle.
Note that as the track wears in it will
periodically need tightening to maintain
the correct tension. It is recommended
that you check track tension at 3 hours,
10 hours and weekly their after.
