•
Replace the shafts if they have wear damage. If
there is wear damage on an expanding sleeve, it is
not sufficiently tightened.
•
Make sure that the pivot joints are lubricated. The
lubrication prevents dirt and water in the pivot joints
and decreases the wear on the shafts and the
bushings.
To examine the rubber components for
wear
•
Examine the caterpillar tracks. If you can see metal
from the reinforcement cord, replace the caterpillar
tracks.
•
