Inspection (Fig. 60)
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 (11) for deep
scratches, out–of–roundness, and bending. Replace if
worn or damaged.
3. Inspect head (3), shaft (6), and piston (8) for exces-
sive pitting, scoring, and wear. Replace any worn or
damaged parts.
Reassembly (Fig. 60)
1. Coat all O–rings, uni–ring, and backup washer light-
ly with hydraulic oil. Install new O–ring (7) and uni–ring
(9) to the piston (8). Install O–rings (2 and 5) and backup
washer (4) to the head (3).
IMPORTANT: Do not clamp vise jaws against shaft
(6) surface. Protect shaft surface before mounting
in the vise.
2. Mount shaft (6) securely in a vise by clamping vise
on the ends of the shaft. Slide head (3) onto the shaft.
Install piston (8) and locknut (10) onto the shaft and
tighten lock nut (10).
3. Remove shaft (6) from the vise.
IMPORTANT: Prevent damage when clamping the
barrel (11) into a vise; clamp on the pivot end only.
Do not close vise enough to distort barrel.
4. Mount barrel (11) 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 (8), shaft (6), and head (3) as-
sembly into barrel (11) being careful not to damage the
seals.
6. Secure head (3) in barrel (11) by installing retaining
ring (1). Align key slot in head with the access groove in
the barrel. 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 Fig-
ure 62.
