LINES AND PORTS
To keep dirt from contaminating fluid systems when removing and installing lines, perform the following steps:
Clean fittings and surrounding area before disconnecting lines.
Cover, cap, plug, or tape lines and ports after disconnecting lines. Use cap and plug set on hydraulic
When these are not available, use hand-carved wooden plugs, clean rags, duct tape, or other similar
materials to prevent dirt from entering system.
Ensure that new and used parts are clean before installing.
Wait to remove cover, cap, plug, or tape from lines and ports until just before installing lines.
END OF TASK
DO NOT use antiseizing tape on air lines. Damage to air valves may result if
antiseizing tape is used.
Apply antiseizing tape only to pipe threads of male fittings of hydraulic system.
DO NOT exceed specified torque or use power tools to tighten fittings taped with
antiseizing tape. Overtightening could damage fitting threads and cause
connection to leak.
Failure to comply may result in damage to equipment.
When connecting hydraulic lines and fittings without compression sleeves or O-rings, antiseizing tape may be
used to keep connections from leaking. Use as follows:
Ensure that threads are clean and dry.
Start antiseizing tape one or two threads from small or leading edge of fitting, joining tape together with
an overlap of about 1/8 in. (3.18 mm) for fittings with fine threads. For fittings with coarse threads, tape
should be wrapped around threads two or three times.
Tightly wrap antiseizing tape in the same direction as you would tighten a nut. Tape must be pressed into
threads without cutting or ripping.
Using hand tools, tighten fittings to specified torque.
