5.6 Track Adjustments
5.6.1 Track Adjustment
After maintenance or over time the track will become slack and will have to be adjusted. The
adjustment of the tracks operates through a tensioning cylinder (C). When the cylinder is filled
with grease it extends and pushes the spring tension unit (B), and the idler (A), forward. The
grease is filled through the track adjuster grease valve (D).
5.6.2 Track Adjustment Settings
In order to establish if the track requires tensioning, move the Host machine a few metres
forwards and backwards on level ground. This allows the tracks to adopt their natural degree of
tension.
Note: Do not slew the machine.
Using a straight edge and a measuring tape, measure the droop of the track group as shown at
(E). For this particular track set, the droop should not exceed 30 mm.
WARNING!
Grease under pressure can cause serious injury. Never unscrew a track
adjuster valve by more than a ½ turn, when the track is under tension.
