Primary Boom Lift Cylinder
The primary boom lift cylinder raises and lowers
the primary boom. The primary boom lift cylinder is
equipped with a counterbalance valve to prevent
movement in the event of a hydraulic line failure.
How to Remove the Primary
Boom Lift 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.
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 Two,
Hydraulic
Hose and Fitting Torque
Specifications.
1 Raise the primary boom until the primary boom
is horizontal.
2 Raise the secondary boom until the primary
boom lift cylinder barrel-end pivot pin is above
the turntable covers.
3 Attach a 5 ton (5000 kg) overhead crane to the
primary boom for support. Do not lift the boom.
4 Support the rod end and the barrel end of the
primary boom lift cylinder with a second
overhead crane or similar lifting device.
5 Tag, disconnect and plug the primary boom lift
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.
6 Remove the pin retaining fastener from the
primary boom lift cylinder rod-end pivot pin. Use
a soft metal drift to remove the pin.
The primary boom will fall if it is
not properly supported when the
primary boom rod-end pivot pin is
removed.
7 Place a support block across both turntable
covers under the primary boom lift cylinder.
8
Z-45/25J Models:
Lower the lift cylinder onto
the block. Protect the cylinder rod from
damage.
Crushing hazard. The primary
boom lift cylinder may fall if it is not
properly supported.
9 Remove the primary boom lift cylinder barrel-
end pivot pin retaining fasteners. Do not
remove the pin.
10 Use a slide hammer to remove the barrel-end
pivot pin. Carefully remove the primary boom lift
cylinder from the machine.
Crushing hazard. The lift cylinder
may become unbalanced and fall
if it is not properly supported and
secured to the lifting device.
