a. Removal
Eye protection will be worn when performing maintenance procedures on all hydraulic components
to avoid injury to personnel.
All hydraulic lines and ports must be capped to prevent contaminants from entering the hydrau-
lic system and causing internal damage to hydraulic components.
All serviceable components must be placed in plastic bags to prevent contamination of hydrau-
lic system during installation.
NOTE
All hydraulic lines and components must be tagged before removal for identification during in-
stallation.
The removal of hydraulic tubes and fittings must be restricted to those items that are to be re-
placed. Therefore, the legends in this chapter are for identification only.
For removal, follow illustration and legend as a guide. Discard all locknuts, preformed packings, and packing
retainers.
b. Installation
When installing any hydraulic fitting, tighten fitting to aline with the connecting lines. Repositioning
can loosen threads, cause leaks, and damage preformed packings.
