Disassembly (Fig. 54)
1. Remove oil from cylinder into a drain pan by slowly
pumping the cylinder shaft. Plug both ports and clean
the outside of the lift cylinder.
IMPORTANT: Prevent damage when clamping the
lift cylinder into a vise; clamp on the pivot end only.
Do not close vise enough to distort the barrel.
2. Mount lift cylinder in a vise so that the shaft end tilts
up slightly.
3. Remove retaining ring (11) from the barrel.
4. Grasp clevis rod (14); extract shaft (6), head (10),
and piston (3) by carefully twisting and pulling the shaft
out from the barrel.
IMPORTANT: Do not clamp vise jaws against shaft
surface. Protect shaft surface before mounting in
the vise.
5. Mount shaft securely in a vise. Remove locknut and
piston from the shaft. Slide head off the shaft.
6. Remove and discard uni–ring (4) and O–ring (5) from
the piston. Remove and discard dust seal (12), backup
washer (9), and O–rings (7 and 8) from the head.
15. Grease fitting
NOTE: If the clevis rod (14) is to be removed from the
shaft (6), note the number of threads exposed between
the jam nut (13) and the smooth surface of the shaft to
help reassembly.
7. Loosen jam nut and remove clevis rod if necessary.
Inspection
CAUTION
Use eye protection such as goggles when using
compressed air.

with compressed air.
2. Inspect internal surface of barrel for deep scratches,
out–of–roundness, and bending. Replace if worn or
damaged.
3. Inspect head, shaft, and piston for excessive pitting,
scoring, and wear. Replace any worn or damaged parts.
