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.
