HYDRAULIC

bar stock approximately 5 inches long and slightly larger

in diameter than the snap ring being installed. Bore a

hole in the stock slightly larger than the stud end of the

spool. Remove any sharp edges. To use sleeve type

tool when ready to install snap ring, compress spring,

then position snap ring on stud end of spool. Position

tool against snap ring, and tap rather sharply, with a

rawhide mallet, until snap ring is seated in groove.

B. REMOVAL

1. Note hydraulic line connections at the valve; tag

if necessary to assure correct hydraulic hook-up on

installation. Disconnect all hydraulic lines, capping all

openings to prevent contamination of the system with

foreign particles. Inspect general condition of the lines,

replacing any that were leaking before being

disconnected or when continued service is doubtful.

NOTE:

Disconnect steel tubing at both ends to

eliminate any possibility of distorting the tube shape.

NOTE: Use two wrenches when removing or replacing

hydraulic lines. This will help prevent changing the

angle of the installed fitting and twisting the lines.

2. Extract cotter pins from the connecting links at

the valve spools. Push roll pins out, to disconnect the

links from the spools. Check each link for elongated

holes and check handle lever-to-spool mechanism for

any signs of impending failure.

3. Remove remaining attaching screws and lift the

valve out of the truck.
