Inspection, Maintenance and Adjustment
4-58
NOTE:
For machines with steel crawlers (optional),
checking and adjustment steps and the
clearance are the same.
How to Adjust Tension
1.
Apply grease through grease fitting.
2.
Move track forward and backward to distribute grease
and readjust tension if necessary.
3.
If tension cannot be increased, replace pin and
bushing, or, on rubber crawlers, replace cylinder seal
or crawler.
To Reduce Tension
1.
Loosening the cartridge valve causes grease to drain
out and track tension to decrease. Loosen valve slowly
a maximum of 1 to turns.
2.
When crawler tension is correct, tighten cartridge valve
to 59 - 88 Nm / 6-9 kg•m (43 - 65 ft lb)
3.
Recheck tension by moving track forward and
backward.
4.
Recheck tension and adjust as necessary.

WARNING!
The track adjusting mechanism is under very
high-pressure. NEVER release pressure too
suddenly. The grease cylinder valve should never
be backed off more than 1 complete turn from the
fully tightened down position. Bleed off pressure
slowly and keep your body away from the valve at
all times. If there is problem in the fitting thread,
the valve or fitting might be ejected at high-speed,
causing a fatal injury.
