Small Rock Valve

Level
These units were designed to have no
adjustment. Before assembling slew lever, use a
wire brush to clean splines on shaft and lever.
Use grease or anti-seize to lubricate splines
during assembly. If you do notice that the Rock is
missing the material cylinder openings, you must
check to see where the problem may be (i.e.,
articulated bearings, shifting cylinder (internal),
or Rock slewing lever may need adjustment).
Please call the Schwing Service Department at
(651) 429-0999 with any questions regarding this
matter.
Slewing Yoke Timing
(Viewed From Cylinder End)
The slewing yoke is installed properly when the
center line of the hydraulic cylinder rod is in line
with the center line of both the slewing shaft and
the inlet or cutting ring. Rock is hanging freely
and the lever is flat on top. A torpedo level will
be centered.
