CLEANING AND INSPECTION

WARNING

Solvent cleaning compound MIL-PRF-680 Type III is an environmentally compliant and low toxic mate-

rial. However, it may be irritating to the eyes and skin. Use protective gloves and goggles. Use in well-venti-

lated areas. Keep away from open flames and other sources of ignition.

Clean all sealing surfaces and tube assembly connections with solvent cleaning compound and allow to dry.

Inspect internal casing of cylinder and internal parts of cylinder for cracks, wear, scoring and damage. If components

and parts are not serviceable, replace lift cylinder.

Ensure mating surfaces for bearing sleeves are clean and not damaged.

ASSEMBLY

NOTE

Lightly coat bearing sleeves, new O-rings, new preformed packing, new ring, new backup ring, new piston

ring, and new seals with clean oil before assembly.

Install new piston ring (26), new ring (25) and new seal (24) on piston (17).

Install new backup ring (23) and new O-ring (22) into inner groove on head (1).

Install new gasket (21) and new preformed packing

(20) in head (1).

Use sandpaper or emery cloth to scuff surfaces of

counterbore inside of head (1) and outside diameter of

dle seal by lip only.

Quick-cure sealant will dry in approxi-

mately 30 seconds.
