Track Tension
Proper track tension is very important for
optimum performance and maximum
track life. Operating with tracks that are
too loose can cause them to misfeed,
possibly causing damage. During the
first 50 hours of operation, the tracks will
"break-in", and may require adjustment.
To check for proper track adjustment:
1. Drive the machine forward 5 feet to
remove slack from the lower and rear
portions of the track.
2. Lay a straight edge along the top of
the track, across the sprocket and the
front idler wheel (photo A).
3. Using a rope or wire, put 50 lbs. of
down force on the track at the mid
point between the sprocket and idler.
4. Using a ruler or tape, measure the
distance between the straight edge
and track (photo B). The track should
not deflect more than .75" between
the top of the track and the straight
edge.
5. If the track does deflect more than
.75", tighten the track until within
specification.
To adjust the track tension:
1. Locate jam nut on track tensioner and
clean the threads thoroughly before
beginning procedure (photo C).
2. Using a wrench, loosen the jam nut
on the track tensioner.
3. After the jam nut is loosened turn the
tensioner until the track tension is
within specification (photo D).
4. Turn the tensioner the opposite direc-
tion to loosen the track.
5. Once proper tension is achieved,
retighten the jam nut on the tensioner.
If the track tensioner is stiff, it may be
helpful to slide a pipe over the end of
the wrench to increase leverage while
adjusting tension.
