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
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 2, Hydraulic Hose
and Fitting Torque Specifications.
