Track Adjustment
Correct track tension is important for good performance
and to prevent the tracks from dismounting. The track
tension is controlled by the forward idler which is attached
to a grease filled hydraulic cylinder. The track tension
should be checked as follows:
1 Position machine on a smooth flat surface
2 Thoroughly clean the track, making sure that all
debris is removed from around the sprocket and
rollers. Drive the machine backwards and forwards
whilst cleaning.
3 Drive the machine forwards to ensure that the slack
is at the top of the track.
4 Using a suitable straight edge, measure the sag at
position B which should be 5 to 10 mm (0.2 to 0.4 in).
5 If adjustment is required, unscrew bolts C and remove
access plate D.
6 To tighten the track, pump grease into nipple E using
a grease gun. To loosen the track, carefully unscrew
hexagon plug F and allow the grease to flow into a
suitable container.
7 When correct adjustment is achieved, replace the
cover plate.
8 Repeat for opposite track.
