Track unit, checking tension
Check and adjust the track tension every 250 hours
NOTE!
Incorrect tension reduces the lifetime of the tracks.
A too low track tension increases the risk of
detracking.
1 Park the machine on horizontal ground.
2 Lower the dozer blade in the back to the ground
until the tracks are slightly raised.
3 Lower the bucket to the ground, operate the
boom until the machine is raised.
4 Run the tracks several times in forward and
reverse.
5 For rubber tracks, measure on both tracks sag
(A) under the roller which is the closest to the
center of the undercarriage, between the track
pad and the track roller.
For steel tracks, measure on both tracks the
upper sag.
6 For rubber tracks: The track is correctly
tensioned if the distance (A) is between 15 to 25
mm (0.59 to 0.98 in).
For steel tracks: The track is correctly tensioned
if the distance between the measurement tool
and the track is between 15 to 25 mm (0.59 to
0.98 in).
7 To reduce track slack on both rubber and steel
tracks, inject grease through the nipple (1) into
the adjustment cylinder.
