The friction lining wear of the clutch is to
be tested every 1000 operating hours.
Worn friction lining should be replaced
immediately.
The clutch is located behind the left-
hand maintenance flap on the control
panel.
Ensure that the drive engine cannot be
started!
The inspection cover (1) of the clutch
casing must be removed to carry out the
inspection.
- Remove the four locking screws (2) of
an accessible inspection cover (1).
- Remove the inspection cover.
- Apply pressure to axial oil feed of
clutch through an external source, en-
suring that the piston is pressed
against the disc pack.
Switching pressure is approx. 35 bar!
The distance (X) between pistons and
cylinders with the clutch activated
amounts to 2 mm in new condition; the
wear limit is 6 mm.
If a positive distance can be measured,
(dimension X>6mm), contact
Dynapac After-Sales Service!

tion cover again properly.
