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 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 Rotate the boom until the turntable
counterweight is between the circle-end and
square-end tires.

2 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.

3 Remove the pin retaining fasteners from the
oscillate cylinder rod-end pivot pin. Use a soft
metal drift to remove the pin.
4 Attach a lifting strap from an overhead crane to
the barrel end of the oscillating cylinder.
5 Remove the pin retaining fasteners from the
oscillate cylinder barrel-end pivot pin. Use a
soft metal drift to remove the pin.
Crushing hazard. The oscillate
cylinder may become unbalanced
and fall if not properly supported
when removed from the machine.
6 Remove the oscillate cylinder from the machine.
