Inspection
CAUTION
Use eye protection such as goggles when using
compressed air
1. Wash all parts in solvent. Dry parts 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.
Reassembly (Fig. 50)
1. Coat all O–rings, uni–ring, and backup washer lightly
with hydraulic oil. Install new O–ring and uni–ring to the
piston. Install O–rings and backup washer to the head.
IMPORTANT: Do not clamp vise jaws against shaft
surface. Protect shaft surface before mounting in
vise.
2. Mount shaft securely in a vise by clamping vise on
the ends of the shaft. Slide head onto the shaft. Install
piston and locknut onto the shaft and tighten lock nut.
3. Remove shaft from vise.
IMPORTANT: Prevent damage when clamping the
barrel into a vise; clamp on the pivot end only. Do
not close vise enough to distort barrel.
4. Mount barrel in a vise so that the shaft end tilts up
slightly.
5. Coat all internal lift cylinder parts with a light coat of
hydraulic oil. Slide piston, shaft, and head assembly into
barrel being careful not to damage the seals.
6. Secure head in barrel by installing retaining ring.
Align key slot in head with the access groove in the bar-
rel. Rotate head clockwise as far as the retaining ring will
allow. The offset end of the retaining ring will be against
the left side of the barrel groove as shown in Figure 52.
