2-20. GENERAL REMOVAL INSTRUCTIONS.

a. Work Required. Remove parts if repair or replacement is required. Do not disassemble a component any

further than needed.

b. Preparation. Before removal of any electrical, hydraulic, or air system components, ensure system component

is not energized or pressurized. Disconnect battery ground cables. On those trucks equipped with a battery disconnect

switch, the switch may be used to disconnect batteries. Relieve air system pressure. Before removal of fasteners (nuts,

locknuts), remove any paint on threads to prevent binding of fastener.

c. Identification. To ease assembly and installation, tag and mark shims, connectors, wires, and mating ends of

lines before disconnecting them. Identify similar parts to ensure correct assembly.

d. Position of Valves. Before removing valve handles, mark or diagram their positions when open and closed.

This will help during assembly.

e. Location. Before removing cable ties, cushion clamps, hoses, tubing, wiring, etc., note the location, position

and routing to ensure correct assembly.

Self-locking fasteners that are loosened must be replaced, not tightened.

Cleanliness. Work area must be as clean as possible to prevent contamination to components.

Locking Parts. Replace all lockwire, lockwashers, cotter pins, and locknuts at time of reassembly.
