Platform Leveling Master Cylinder
The platform leveling master cylinder acts as a
pump for the slave cylinder. It is part of the
closed-loop hydraulic circuit that keeps the platform
level through the entire range of primary boom
motion. The platform leveling master cylinder is
located inside the upper mid-pivot at the pivot end
of the primary boom.

How to Remove the Platform
Leveling Master Cylinder
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.
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.
Note: Before cylinder removal is considered, bleed
the cylinder to be sure that there is no air in the
closed loop. Refer to Repair Procedure,
How to
Bleed the Slave Cylinder
.
1
Remove the rear turntable cover.
2
Raise the secondary boom until the master
cylinder barrel-end pivot pin is above the
turntable counterweights.
3
Raise the primary boom until the master
cylinder rod-end pivot pin is accessible.
4
Attach a lifting strap from an overhead crane
to the upper pivot for support. Do not apply
any lifting pressure.
5
Secure the upper secondary boom to the pivot
end of the primary boom with a strap.
Note: Securing the upper secondary boom to the
pivot will prevent the upper secondary boom from
falling when the master cylinder barrel-end pivot
pin is removed from the cylinder.
6
Tag, disconnect and plug the master cylinder
hydraulic hoses. Cap the fittings on the
cylinder.
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.
7
Tie a strap around the lug on the rod end of
the master cylinder and secure the strap to the
primary boom.
Note: The strap will be used to lower the cylinder
out of the upper pivot.
