Oscillating Axle
Lock-out Cylinders
The oscillating axle cylinders extend and retract
between the drive chassis and the oscillating axle.
The cylinders are equipped with counterbalance
valves to prevent movement in the event of a
hydraulic hose failure.
How to Remove an Oscillating
Axle Cylinder
Bodily injury hazard. This
procedure requires specific repair
skills 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.
Perform this procedure on a firm,
level surface with the boom in
the stowed position.
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 Rotate the turntable until the boom is between
the steer tires.

2 Remove the fasteners from drive chassis cover
at the steer end. Remove the cover.
3 Tag, disconnect and plug the oscillating axle
cylinder hydraulic hoses. Cap the fittings on the
oscillate 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.
4 Remove the pin retaining fasteners from the
rod-end pivot pin. Use a soft metal drift to
remove the pin.
5 Attach a lifting strap from an overhead crane to
the barrel end of the oscillating cylinder.
6 Remove the pin retaining fasteners from the
barrel-end pivot pin. Use a soft metal drift to
remove the pin.
7 Remove the oscillate cylinder from the machine.
Crushing hazard. The oscillate
cylinder could become unbalanced
and fall when it is removed from
the machine if it is not properly
attached to the overhead crane.
