NOTE:
For machines with steel tracks, checking and
adjustment steps and clearance are the same.
The track adjusting mechanism is under very
high-pressure. NEVER release pressure too suddenly.
The track tension grease 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 a problem with the valve threads, the valve
might be ejected at a high-speed, causing a fatal
injury.
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 tracks, replace cylinder seal or tracks.
To Reduce Tension
1. Loosening track tension grease valve causes grease to
drain out and track tension to decrease. Loosen valve
slowly a maximum of 1 to turns.
2. When track tension is correct, tighten track tension grease
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.
