1.
Stop your machine on a flat
and solid surface.
2.
Lift it in safe conditions and
put stable supports under
the undercarriage frame to
properly support it.
3.
Measure distance A at the
central roller of the undercarriage from the bottom of the roller to the rigid inside surface of the
rubber track. Track tension is normal if dimension A is between 70 and 75 mm.
4.
Adjust tension as described in the following paragraph if track tension does not comply with
these dimensions (loose or too tight).
A
Track tension is maintained by grease in the adjuster unit. Adding more grease will increase track
tension, removing grease will decrease it.
The grease contained in the hydraulic track tensioner ram is pressurized. Never release grease nipple
(No. 1, Fig. 1) for more than necessary to slowly release grease to a maximum of five turns. If the valve
is loosened too much you risk expelling grease under pressure and possible injury to the machine
operator. Remove gravel or mud when they are jammed between the sprocket and the track link
before loosening the track.
1.
Locate access hole in side frame (fig. 1) to access the adjustment system.
2.
To loosen the track turn the grease nipple counter-clockwise slowly, the grease should begin to
be expelled after approximately two turns.
3.
If grease does not start to drain out then slowly rotate the track forward and reverse to free
adjuster mechanism - grease may then be expelled under pressure as track tension is relieved.

4.
When you have obtained correct track tension then turn valve
clockwise and tighten it. Clean all traces of extruded grease.
5.
To stretch the track connect a grease gun to grease nipple and
add grease until track tension falls within specified values.

TRACK LOOSENING/TIGHTENING PROCEDURES
WARNING
It is not normal for the track to remain too tight after turning the
grease nipple counter-clockwise or for it to remain loose after in-
troducing grease into the grease nipple. Never try to remove the
tracks or disassemble the track-stretching cylinder since pressure
of the grease inside the track is dangerous.
