1.2 Points of maintenance
Track tightness (1)
m
Slack tracks may slip out of the guides of
the rolls, drive and guide wheels and in-
tensive wear may take place.
m
Too tight tracks add to the wear of guide wheels and drive bearings, the pins and
bushes of the tracks as well.
Track tension: checking / adjusting:
- Track tightness can be adjusted with
grease press. The filling ports are lo-
cated on the LH and RH sides of the
running gear.
- Run paver drive unit onto a suitable
piece of angled timber (C) or onto a
similar object.
- To relieve strain on the track, reverse
a short distance, ensuring that the ve-
hicle remains on the angled timber.
A
The tack is correctly tensioned once the
slack (F) between centre roller and track
is 30-40 mm.
A
If a different level of slack is detected
during the measurement process, pro-
ceed as follows:
- Drive the vehicle forwards slightly, to
relieve strain on the upper track sec-
tion.
- Remove the screws (A).
- Remove cap (B).
- Screw the head module of the flat grease nipple (toolbox) on the grease press.
- Fill the track tensioner with grease, then remove the grease gun.
- Next, drive the vehicle forwards and backwards a few times.
- Check the track tension once again, as described above.
A
Repeat this procedure on both drive units!
- Remount the lid (B).
