Boom Lift Cylinder
How to Remove a Lift Cylinder
Note: 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.
1 Attach a lifting strap from an overhead
10 ton / 10,000 kg crane to the fork end of the
boom. Support the boom. Do not apply any
lifting pressure.
2 Tag, disconnect and plug the hydraulic hoses at
the lift cylinder manifold. Cap the fittings.
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.
Component damage hazard.
Hoses can be damaged if they are
kinked or pinched.
3 Attach a lifting strap from an overhead crane to
the rod end of the lift cylinder. Support the
cylinder. Do not apply any lifting pressure.
4 Remove the fasteners securing the lift cylinder
barrel-end pivot pin to the chassis.
5 Use a soft metal drift to remove the pivot pin.
6 Remove the fasteners securing the lift cylinder
rod-end pivot pin to the boom.
7 Use a soft metal drift to remove the pivot pin.
Crushing hazard. The boom will
fall if not properly supported when
the pivot pin is removed from the
machine.
8 Using the overhead crane, raise the boom to a
horizontal position. Remove the cylinder from
the machine.
Crushing hazard. The cylinder will
fall if not properly supported when
removed from the machine.
