Dump body
Check the dump body rubber cushions, which fit up against
the top of the trailer unit frame, every 1000 hours. A first
check should be carried out after 100 hours and also after
replacing.
Rubber cushions, checking and adjusting
vertically
Before checking, the respective rubber cushions and the top of the
frame should be cleaned.
The dump body must be empty and lowered onto the frame and
the tipping control in position 2 operating position (lowering/
floating position). When adjusting, it is important that any
clearance and compression becomes the same on both sides of
the trailer unit frame.
The rear rubber cushions (C), located over the bogie, should fit up
against the body and be compressed to the same extent on both
sides.
At the same time, the front rubber cushions (A) should have a
clearance of 18–22 at the leading edge and (B) 15–19 mm at the
trailing edge between rubber cushions and trailer frame.
Cushion (B) should be 3 mm higher than cushion (A).
Adjust with shims under the rear rubber cushions.
IMPORTANT! It is important that the area around and under
the rubber cushions is kept clean. Dirt, which collects here,
considerably increases the risk of damage to the machine,
primarily to the frame.
Adjusting washers, checking and adjusting
dump body sideways
At the rear attachment of the dump body, the tipping joint, a max.
1 mm (0.04 in) clearance is permitted at each tipping joint bearing.
Adjust with adjusting washers (A).
For adjusting the axial clearance of the tipping joint, use adjusting
washers.
At the front side guide of the dump body, a clearance of max. 1 mm
is permitted on each side. Adjust with shims.
Body height extension for light material
If the machine is equipped with a body extension for light, the
tailgate's lock mechanism should be adjusted.
Adjustment is done with tensioned chain and loaded dump body.
Check tailgate and lock mechanism daily.
WARNING!
Keep away from the area under the dump body when it is
raised, unless it has been secured with the dump body lock
and the tipping control has been locked with the lock-out
control, see page 100.
