1 Position the track so that it locates under the bottom
rollers and around the front and rear idler wheels.
Position a support under the track to take up the sag
at the bottom.
2 Place a steel bar under the track adjacent to the
sprocket and support the weight of the track.
3 Assemble the sprocket to the motor flange and
tighten the securing bolts. Operate the track motor to
rotate the sprocket as necessary to locate its teeth
into the grooves of the track.
4 Lower the track onto the sprocket and remove the
hoist and bar.
5 Pump grease into the adjuster to extend the front idler
wheel ensuring that the track is correctly located on
the idler wheels and guide rollers.
6 Lower the machine to the ground and adjust the track
tension (see Section 3). When correctly tensioned
there should be 5 to 10 mm (0.2 to 0.4 in) sag at the
top of the track.
7 Replace the access cover.
Recheck the track adjustment after the machine has been
driven for a while.
