GENERAL MAINTENANCE INSTRUCTIONS - CONTINUED
HYDRAULIC SYSTEM MAINTENANCE - CONTINUED
Ensure no hose is twisted, stretched or kinked. Hoses that are twisted or kinked can close off flow through
the system and lead to component failure.
Screw on both tube nuts with your fingers to position tubing and clamps correctly before tightening tube nuts.
Put anti-seizing tape MIL-T-27730 on pipe (tapered) threads. Do not put tape on first two threads.
Operate the system being worked on and check the system for leaks at all connections that were loosened. If a connec-
tion leaks, unscrew one full turn, then tighten. If it is still leaking, replace leaking parts.
Always look carefully at equipment for likely signs of trouble while doing routine work. If hydraulic oil is leaking down
on harnesses and connectors, repair the leak at once. Tie down any harness that is free to move and rub against metal. If
you look for possible trouble spots and make repairs at once, you can cut down on repair time and extra work.
Installing adjustable fittings.
Put a light coat of lubricant, same as lubricant in system being worked on, on packing (1). Slide packing on fitting
(2) so that packing is seated in groove against washer (4) as far as it will go.
Turn locknut (5) clockwise until it touches washer (4).
Screw fitting (2) into boss (6) until washer (4) touches boss.
Turn fitting (2) counterclockwise, up to one full turn, until desired position is reached.
Whenever possible, hold fitting (2) in position with one wrench and tighten locknut (5) clockwise with other
The following are general practices regarding the use of tools:
Always use the proper tool kit and tools for the procedure being performed.
Ensure that tools are clean and lubricated to reduce wear and to prevent rust.
Keep track of tools. Do not be careless with them.
Return tools to toolbox when finished with repair or maintenance.
Return toolboxes and tools to tool storage when not in use.
Inventory tools before and after each use.
Some maintenance tasks may require special or fabricated tools. The "Initial Setup" of the procedure will specify any
special or fabricated tools needed to perform that procedure. Use these special tools only for the maintenance procedures
for which they are designed or called out. If you are unfamiliar with a required tool, see your supervisor.
TAGGING WIRES AND HOSES
Use marker tags (Item 42, WP 0339 00) to identify all electrical wires; fuel, oil, coolant, and hydraulic lines; and any
other parts that may be hard to identify or replace later. Fasten tags to parts during removal by wrapping wire fasteners
around or through parts and twisting ends together. Position tags to be out of the way during cleaning, inspection and
repair. Mark tags with a pencil, pen or marker.
