Oscillating Axle 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 line failure. The valves are not
adjustable.
How to Remove an Oscillating
Axle Cylinder
Note: Perform this procedure on a firm, level
surface with the boom in the stowed position.
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 Tag, disconnect and plug the oscillating axle
cylinder hydraulic hoses. Cap the fittings on the
oscillate cylinder.

connections very slowly to allow
the oil pressure to dissipate
gradually. Do not allow oil to
squirt or spray.

rod-end pivot pin. Use a soft metal drift to
remove the pin.
3 Attach a lifting strap from an overhead crane to
the barrel end of the oscillating cylinder.
