Adjusting the caterpillar track
(STH 10.66 C)
Figure 6
The caterpillar track (1) is correctly
adjusted if it can be forced down by
hand by 10–12 mm. If it can be
forced down by a greater or lesser
amount, it must be adjusted:
•
Set the machine on a secure and
horizontal support so that the
caterpillar tracks no longer touch
the ground.
•
Rotate nut (2) until the caterpillar
track has the correct tension:
– To tighten, rotate in clockwise
direction
– To slacken, rotate in anti-
clockwise direction.

adjust the tension of the new
caterpillar track with the nut (2)
(see “Adjusting the caterpillar
track”).
Replacing a shear bolt
Figure 9
The worm (3) is fastened to the drive
shaft (4) with shear bolts (1) and
lock-nuts (2). The bolts are
constructed in such a way that they
break (shear off) if the worm strikes
solid extraneous objects. In this
way damage to the machine is
prevented. These bolts (1) and nuts
(2) may only be replaced with
original spare parts (two replace-
ment bolts and lock-nuts are
supplied with the machine):
•
Remove sheared-off bolt and nut,
clean place of attachment and
lubricate it.
•
Use a new shear bolt and lock-nut
to replace the broken one.
