Boom Lift Cylinder
The boom lift cylinder raises and lowers the boom.
The boom lift cylinder is equipped with
counterbalance valves to prevent movement in the
event of a hydraulic line failure.
How to Remove the 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.
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
Raise the boom to a horizontal position.
2
Attach a 5 ton / 5000 kg overhead crane to the
boom at the platform end for support. Do not
lift the boom.
3
Support and secure both ends of the boom lift
cylinder to a second overhead crane or similar
lifting device.
4
Remove the pin retaining fastener from the
boom lift cylinder rod-end pivot pin. Use a soft
metal drift to remove the pin.
Crushing hazard. The boom will
fall if not properly supported
when the primary boom rod-end
pivot pin is removed.
5
Using auxiliary power, activate the boom down
function so the cylinder will retract. Retract the
cylinder just enough until the rod end of the
cylinder will clear the mounting bracket on the
boom. Turn the machine off.
6
Tag, disconnect and plug the 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.
7
Remove the pin retaining fasteners from the
boom lift cylinder barrel-end pivot pins. Do not
remove the pins.
