Oscillating Axle Cylinders
The oscillate system is designed so that all four
tires maintain firm contact to the ground on unlevel
terrain improving traction and machine stability.
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 the Oscillate
Cylinder
Note: Perform this procedure on a firm, level
surface with the machine 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 Rotate the turntable until the boom is between
the steer tires or tracks.
2 Tag, disconnect and plug the oscillating axle
cylinder hydraulic hoses. Cap the fittings on
the 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
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
barrel-end pivot pin. Use a soft metal drift to
remove the pin.
6 Remove the cylinder from the machine.
Crushing hazard. The oscillate
cylinder may become
unbalanced and fall when
removed from the machine if not
properly attached to the
overhead crane.
