REMOVING THE RUBBER TRACKS
Remove gravel or mud when they are jammed between the
sprocket and the track link before loosening the track.
Stop your machine on a solid and level surface. Lift it up and 1
support it in safe conditions.
Locate grease nipple under coverplate in side frame to 2
access to the adjustment system (No. 1, Fig. 1).
To loosen a track turn the grease nipple counter-clockwise 3
slowly then the grease should begin to be expelled after
approximately 2 turns.
If grease does not start to drain out then slowly rotate the 4
track forward and reverse to free adjuster mechanism.
Using levers exercise force sideways to slide the track off the 5
track-stretching wheel.
Remove track from drive sprocket end.6

TRACK LOOSENING/TIGHTENING PROCEDURES
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
pressurised. 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.
Locate grease nipple under coverplate in side frame (Fig. 1) 1
to access the adjustment system.
To loosen the track turn the grease nipple counter-clockwise 2
slowly, the grease should begin to be expelled after
approximately two turns.
If grease does not start to drain out then slowly rotate the 3
track forward and reverse to free adjuster mechanism -
grease may then be expelled under pressure as track tension
is relieved.
When you have obtained correct track tension then turn 4
valve clockwise and tighten it. Clean all traces of extruded
grease.
To stretch the track connect a grease gun to grease nipple 5
and add grease until track tension falls within specified
values.

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
INTRODUCING 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.
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 PRESSURISED GREASE MAY
EXIT AND CAUSE INJURY TO THE
MACHINE OPERATOR.
