Oscillate Cylinders
The oscillating axle cylinders extend and retract
between the drive chassis and the axle to maintain
a level chassis while driving over uneven terrain.
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.
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

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.
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.
