2-1
Platform Leveling Cylinder
The slave cylinder and the rotator pivot are the two
primary supports for the platform. The slave
cylinder keeps the platform level through the entire
range of boom motion. It operates in a closed-
circuit hydraulic loop with the master cylinder. The
slave cylinder is equipped with counterbalance
valves to prevent movement in the event of a
hydraulic line failure.
How to Remove the Platform
Leveling Cylinder
Note: Before cylinder removal is considered, bleed
the leveling cylinder to be sure there is no air in
the closed loop.
Note: When removing a hose assembly or fitting,
the O-ring (if equipped) on the fitting and/or hose
end must be replaced. All connections must be
torqued to specification during installation. Refer to
Specifications,
Hydraulic Hose and Fitting Torque
Specifications.
1 Extend the primary boom until the slave
cylinder barrel-end pivot pin is accessible.
2 Raise the jib boom slightly and place blocks
under the platform for support.
3 Lower the jib boom until the platform is resting
on the blocks just enough to support the
platform.
Note: Do not rest the entire weight of the jib boom
on the blocks.
4 Tag, disconnect and cap the hydraulic hoses
from the slave cylinder. Plug the union hoses
from the master cylinder together using a
connector.
Bodily injury hazard. Spraying
hydraulic oil can penetrate and
burn skin. Loosen hydraulic
connections very slowly to allow
the oil pressure to dissipate
gradually. Do not allow oil to
squirt or spray.
5 Remove the pin retaining fastener from the
slave cylinder rod-end pivot pin. Do not
remove the pin.
6 Remove the external snap rings from the
slave cylinder barrel-end pivot pin. Do not
remove the pin.
7 Place a block under the slave cylinder for
support. Protect the cylinder rod from
damage.
8 Use a soft metal drift to drive the rod-end
pivot pin out.
Crushing hazard. The platform
could fall when the leveling
cylinder rod-end pivot pin is
removed if not properly
supported.
Component damage hazard.
The leveling cylinder rod may
become damaged if it is allowed
to fall if not properly supported
by the lifting device.
9 Use a soft metal drift and drive the barrel-end
pin out.
10 Carefully pull the cylinder out of the primary
boom.
