6.8 Replacing and dismantling the
opening and closing cylinders
Remove both arms as described above.
Close the cylinders completely
Disconnect the device’s hydraulic system
from that of the truck (paying careful
attention to oil leaking from the tube, place a
container below to catch it)
Remove the device’s lower brackets (n°14),
hook the ropes up to the device’s frame and
dismantle the truck plate. For convenience,
place a pallet below the device.
Remove the hydraulic connections between
the cylinder buds and the device’s hydraulic
system. Pay careful attention to oil leaks
from the joints.
Remove the cylinder blocking nut
ATTENTION
: switch off truck power before commencing cylinder dismantling and reassembling
operations. Pay careful attention to oil leaks from tubing and joints on cylinder. Place a container
beneath to receive any leaks.
NOTE
: before replacing the rod, check its condition to ensure that it is not damaged or scratched and
that there are no impurities on its surface that could hinder perfect sliding of the parts and therefore the
functioning of the UTB. Check that the inner surface of the cylinder jacket is clean.
