How to Remove an Outrigger
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 Extend the outrigger until the pad just touches
the ground. Do not rest the weight of the
machine on the outrigger.
2 Tag, disconnect and plug the two hydraulic
supply hoses at the outrigger cylinder. 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 barrel end of the outrigger cylinder. Support
the cylinder. Do not apply any lifting pressure.
4 Remove the fasteners securing the outrigger
cylinder barrel-end pivot pin to the chassis.
