1.
Check that the grease contained in the hydraulic cylinder has
been removed.
2.
Mesh the track links in the sprocket and place the other end of
the track on the track-stretching wheel.
3.
Rotate the driving gear in reverse and pull the track soles inside
the frame.
4.
Position the track using a steel tube and turn the driving gear again.
5.
Make sure track links mesh correctly in the sprocket and in the
track stretching wheel.
6.
Adjust track tension (see track loosening procedures on page 24).
7.
Set the tracked undercarriage on the ground.
Measuring wear on sprocket and driving gear teeth is one of the most difficult measurements to be
done. You must always consider the point where wear is greatest.
There should always be enough tooth left on the sprocket to engage fully with the rubber track. When
the sprocket meshing distance is reduced significantly the sprocket should be changed.

Remove gravel or mud when they are jammed between the sprocket and

To loosen a track turn the grease nipple counter-clockwise slowly
then the grease should begin to be expelled after approximately

If grease does not start to drain out then slowly rotate the track
forward and reverse to free adjuster mechanism.
5.
Insert three steel tubes inside the track in the space between the
rollers.
6.
Rotate the driving gear in reverse so that the steel tubes proceed with the track and engage in
the track-stretching wheel.

WARNING
The grease contained in the hydraulic tensioner is under pressure.
Never loosen the grease nipple for more than 5 turns. If the grease
nipple is loosened too much then pressurized grease may exit and
cause injury to the machine operator.
WARNING
Make sure that you are always in safe conditions with the machine
lifted to perform the operation for track installing.
