CHECK AND ADJUSTING TRACK TENSION:
M
ACHINE LIFTING
•
•
Two operators must carry out these operations. One
must travel the machine according to signal from the
other. The track tension cam be verified only when the
track is lifted.
•
Be careful do not low down the machine while the
operator is checking the tension.
The wear of the rubber shoe will vary with the working conditions and type of
soil. Therefore, it is necessary to inspect the wear and track tension
frequently.
After fitting new parts, be sure to carry out the first inspection after 30 hours
of use. In this while, ad just frequently the tension until the initial slack is
complete, to avoid rubber shoe falling down.
Tension adjustment:
1. Park the machine on a level and solid ground.
2. Put the dozer blade on the
machine’s rear, then extend the
blade cylinder completely until
the track will lift a little.
The standard tension is optimal when the clearance between the roller
surface of the track shoe and the track roller tread at the second track roller
from the sprocket is as showed in the table below:
Standard
value
20 – 40 mm
Clearance
Slack track
min. 40 mm
S
LACKS TRACKS
If the machine works with slack tracks they may drop off or
wear too fast.
