MAINTENANCE PROCEDURES
ADJUSTMENT
The grease contained in the hydraulic cylinder is pressurized. For this reason, do not give the grease
q
valve (1) more than one turn when loosening it; in fact, if the valve is loosened excessively it may be
pushed out due to the grease pressure and this is very dangerous for the operator..
Do not loose any component apart from the valve (1). If the track tension does not decrease after this op-
eration, contact your Komatsu Distributor.
If the resistance met when injecting the grease is excessive, move the machine forward and backward
q
covering a short distance.
To increase the track tension, proceed as follows:
1.
Carefully clean the grease valve (1) and inject grease
through the grease nipple (2) until reaching the desired ten-
sion.
2.
When after the injection of grease the idler roller sliding plate
reaches the measure «S» of 0 mm and the track is not suffi-
ciently stretched, this means that the pins and bushings are
excessively worn. Therefore, it is necessary to exchange or
replace the pins and bushings.
For any replacement or repair, contact your Komatsu Distrib-
utor.
