Inspection of Crawler Track
The machine needs to be raised to inspect the
track tension. If the machine drops by mistake
during inspection, a serious injury may result. Be
very careful when the machine is raised.
The conditions of wear and sag of the crawler tracks differ
with the conditions of the work sites. If the slack crawler
tracks are used, they may be slipped off. Inspect and
adjust their tension as the necessity requires.
Inspection
1. Raise the machine using the attachment and blade
until the crawler tracks become apart from the ground.
Support the crawler frame securely with blocks, etc.
2. Measure the clearance between the tread of the
lower roller near the center and the tread of the
crawler track.
The tension is proper if the clearance is as shown
below.
10 to 20 mm (Rubber track)
30 to 50 mm (Steel track)
Raise the machine
until the tracks are
apart from the ground.
