NOTE: The service procedure for the ProCore Proces-
sor lift cylinder and offset cylinder is the same.
Disassembly (Fig. 22)
1. Remove oil from the lift cylinder into a drain pan by
slowly pumping the cylinder rod. Plug ports and clean
the outside of the lift cylinder.
IMPORTANT: Prevent damage when clamping the
lift cylinder into a vise; clamp on the pivot only.
2. Mount lift cylinder in a vise so that the shaft end tilts
up slightly.
3. Using a spanner wrench, rotate head (item 9) clock-
wise until the edge of the retaining ring (item 8) appears
in the tube opening. Insert a screwdriver under the bev-
eled edge of the retaining ring to start the retaining ring
through the tube opening. Rotate the head counter--
clockwise to remove retaining ring (Fig. 23).

carefully twisting and pulling on the rod.
IMPORTANT: Do not clamp vise jaws against rod
surface. Protect rod surface before mounting in
