7.14 Track Tension Adjustment
1. Shut the machine down as
described in section 5.13, locate
jam nut on track tension device
and clean the threads thoroughly
before proceeding. (fig. 7.14-1).
2. Using a wrench, loosen the jam
nut (item 1) on the track tension
device. (fig. 7.14-1)
3. Once the jam nut is loose,
turn the tensioner until the
track tension is within
specification (figure 7.14-2).
4. Turn the tensioner the opposite
direction to loosen the track.
5. Once proper tension is achieved,
retighten the jam nut on the tensioner.
Note: If the track tensioner is stiff, it may be helpful to apply a penetrating lubri-
cant onto the threads prior to adjusting tension.
