Section 3 • Repair Procedures
8 Remove the external snap rings from the
extension cylinder rod-end pivot pin at the
platform end of the extension tube. Use a soft
metal drift to remove the pin.
9 Support and slide the extension cylinder out of
the base end of the extension tube. Place the
extension cylinder on blocks for support.
WARNING
Crushing hazard. The extension
cylinder could become
unbalanced and fall when
removed from primary boom
extension tube if not properly
supported.
During removal, the overhead crane strap will
need to be carefully adjusted for proper balancing.
PRIMARY BOOM COMPONENTS
The platform leveling master cylinder acts as
a pump for the slave cylinder. It is part of the
closedloop hydraulic circuit that keeps the platform
level through the entire range of primary boom
motion. The platform leveling master cylinder is
located at the base of the primary boom.
WARNING
Bodily injury hazard. This
procedure requires specific
repair skills, lifting equipment
and a suitable workshop.
Attempting this procedure
without these skills and tools
could result in death or serious
injury and significant component
damage. Dealer service is
strongly recommended.
When removing a hose assembly or fitting, the
O-ring on the fitting and/or hose end must be
replaced and then torqued to specification during
installation. Refer to Section 2,
Hydraulic Hose
and Fitting Torque Specifications
.
Before cylinder removal is considered, bleed the
cylinder to be sure that there is no air in the closed
loop. See 2-1,
How to Bleed the Slave
Cylinder
