2-21. GENERAL REMOVAL INSTRUCTIONS.
Work Required. Remove parts if repair or replacement is required. Do not disassemble a component any
further than needed.
Preparation. Before removal of any electrical, hydraulic, or air system components, ensure system component
is not energized or pressurized. Disconnect battery ground cables, the FRS is equipped with a battery disconnect switch,
the switch may be used to disconnect batteries. Before removal of fasteners (nuts, locknuts). Remove any paint on threads
to prevent binding of fastener.
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.
Position of Valves. Before removing valve handles, mark or diagram their positions when open and closed.
This will help during assembly.
Location. Before removing cable ties, cushion clamps, hoses, tubing, wiring etc., note the location, position and
routing to ensure correct assembly.
2-22. GENERAL DISASSEMBLY INSTRUCTIONS.
Cleanliness. Work area must be as clean as possible to prevent contamination to components.
Self-locking fasteners that are loosened must be replaced, not tightened.
Locking Parts. Replace all lockwire, lockwashers, cotter pins and locknuts at time of reassembly.
Expendable Parts. All gaskets, packings and seals removed during repair must be discarded and replaced with
Removing Seals. Be sure all traces of oil, gaskets and sealants are removed from components. When
possible, use wood or plastic probes and scrapers to prevent damage to machined surfaces.
Do not use tape to close off fuel or oil openings. Sticky surface of tape can mix with fuel and
oil and cause engine malfunctions.
Parts Protection. To keep dust, dirt, moisture and other objects out of internal parts of systems or
components, cap or tape over all open tubes, hoses, air lines, fittings and component openings as soon as part is
removed. Wrap all removed parts in clean paper or dip parts in preservation oil.
