b. Frame Tilt or Stabilizer Cylinder Disassembly
Note: An additional O-ring may be included at the base
of the cylinder rod. This additional O-ring may be
discarded, as it served only in a temporarily protective
role to keep paint off the rod while the cylinder was
painted at the factory.
1. Clamp the cylinder (1, Fig. 9– 68) in a soft-jawed vise
or other holding device, and place a suitable
container beneath the cylinder to catch hydraulic fluid
run-off.
2. Remove the manifold block from the mounting boss
(ref.) as required. Loosen the 3/8-16 x 3-3/4" hex-
head capscrews securing the manifold block to the
cylinder mounting boss in an alternating pattern.
Note: Significant pressure may be trapped inside the
cylinder. Exercise caution when removing the manifold
block.
3. Remove the 3/8-16 x 3-3/4" hex-head capscrews, 3/
8" lockwashers, four SAE 3/8" washers, and O-rings.
Remove the dual pilot-operated check manifold from
the cylinder at the manifold block mounting boss
(ref.).
