To adjust track tension:
1. Loosen the two bolts (A) securing the front of the
drive table.
Note: If the mounting slots in the drive table do not provide
enough adjustment to achieve proper track tension, the bolts
may be relocated to one of three pairs of threaded mounting
holes located in the undercarriage directly beneath the drive
table.
2. Once these bolts have been loosened or relocat-
ed, loosen the lock nut (B) on the turnbuckle (C)
and adjust by turning the turnbuckle itself.

3. Once proper tension has been achieved, tighten
the turnbuckle lock nut and the two bolts securing
the front of the drive table to complete the proce-
dure.
4. Repeat the adjustment procedure on the other side
of the machine if necessary.
Note: The two bolts (D) securing the rear of the drive table
do not need to be loosened to adjust track tension. They
support the rear of the drive table via bushings that follow
their respective slots as the track is tightened or loosened.
Note: Tensioning can also be performed during track installa-
tion prior to installing the turnbuckle. Do this by pushing the
drive table (all four bolts installed, but front two loose) back-
ward with a port-a-power until proper track tension is
achieved. Once in place, measure the track deflection to
check tension and then install the turnbuckle, turning as
needed to align mounting sleeves and bracket holes. Install
pins and clips to secure the turnbuckle in place and then
tighten the turnbuckle lock nut and the two front drive table
bolts. Repeat on the other side of the machine if necessary.
Drive Sprocket Rollers
Terex compact track loaders utilize rollers on the drive
sprockets to drive the track. These rollers help mini-
mize friction between the track and the drive sprocket
to prolong track life.
The rollers rotate around hardened steel pins and usu-
ally wear on their inside surfaces. As they wear, the
rollers become thinner, but will continue to function as
long as they rotate freely around the pins. Sprocket
rollers should be inspected every 50 hours of operation
and replaced if cracked or worn to less than 35% of
original thickness. (.088"or .22cm)
