Disassembly (Fig. 96)
1. Remove oil from steering cylinder into a drain pan by
slowly pumping the cylinder shaft. Plug both ports and
clean the outside of the cylinder.
IMPORTANT: Prevent damage when clamping the
steering cylinder into a vise; clamp on the clevis end
of the barrel ONLY.
2. Mount steering cylinder securely in a vise by clamp-
ing on the clevis end of the barrel. Use of a vise with soft
jaws is recommended.

ing. Insert a screwdriver under the beveled edge of the
retaining ring to start the retaining ring through the open-
ing. Rotate the head counter--clockwise to remove re-
taining ring from barrel and head.
4. Remove plugs from ports. Extract shaft, head and
piston by carefully twisting and pulling on the shaft.
IMPORTANT: To prevent shaft damage, do not
clamp shaft surface in a vise.
