(Ref. Fig. 7-16) The rear oscillation lock cylinder is located near the rear of
the machine, on the left side. The cylinder is mounted vertically with the
base end secured to the frame and the rod end mounted to the rear axle.
The oscillation control block is mounted to the inboard side of the cylinder
and controls hydraulic flow to and from the cylinder. When hydraulic fluid is
trapped in the cylinder the frame is prevented from rotating around the rear
axle.
The rear oscillation lock cylinder and the oscillation control block are
components of the rear oscillation lock system. See "Rear Oscillation Lock
System" on page 7-17 for more information.
