Section IV. Direct Support/General Support Maintenance Introduction
5-8. LOAD HANDLING SYSTEM (LHS) MAINTENANCE INTRODUCTION.
This section contains maintenance instructions for repairing, replacing, installing, and servicing the Load
Handling System (LHS) components as authorized by the Maintenance Allocation Chart (MAC) at the Direct
Support Maintenance level.
5-9. 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 component ensure system component
is not energized or pressurized. Disconnect battery ground cable. Relieve hydraulic system pressure.
Before removal of fasteners (nuts, locknut) 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.
5-10. GENERAL DISASSEMBLY INSTRUCTIONS.
CAUTION
Self-locking fasteners that are loosened must be replaced, not tightened.
a. Cleanliness. Work area must be as clean as possible to prevent contamination to components.
b. Locking Parts. Replace all lockwashers, cotter pins, and locknuts at time of reassembly.
c. Expendable Parts. All gaskets, packings, and seals removed during repair must be discarded and
replaced with new parts.
d. 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.
CAUTION
Do not use tape to close off oil openings. Sticky surface of tape can mix with oil and cause
hydraulic system malfunctions.
e. 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, fittings, air lines, and component openings as
soon as part is removed. Wrap all removed parts in clean paper or dip parts in preservation oil.
