TM 10-3930-659-34 2-18.  ELECTRICAL GROUND POINTS (Con’t). (4) Look for cracks, loose terminal lugs, and stripped threads.  Replace any defective parts. (5) Install hardware connecting ground cable terminal lug to ground point.  Ensure that all hardware is tight. 2-19.  LINES AND PORTS. To keep dirt from contaminating fluid systems when removing and installing hydraulic, fuel, oil, and coolant lines, perform the following steps: (1) Clean fittings and surrounding area before disconnecting lines. (2) Cover, cap, plug, or tape lines and ports after disconnecting lines.  When these are not available, use hand- carved  wooden  plugs,  clean  rags  (Item  43,  Appendix  B),  duct  tape  (Item  51,  Appendix  B),  or  other  similar  materials  to prevent dirt from entering system. (3) Ensure that new and used parts are clean before installing. (4) Wait to remove cover, cap, plug, or tape from lines and ports until just before installing lines. 2-20.  ANTISEIZING TAPE. When  connecting  hydraulic,  fuel,  and  oil  lines  and  fittings  without  compression  sleeves  or  packings,  antiseizing tape (Item 50, Appendix B) may be used to keep connections from leaking.  Use as follows: (1) Ensure that threads are clean and dry. (2) Start  antiseizing  tape  one  or  two  threads from small or leading edge of fitting, joining tape together with an overlap of about X in.  (3.18 mm) for fittings with fine   threads.      For   fittings   with   coarse   threads,   tape should be wrapped around threads two or three times. (3) Tightly    wrap    antiseizing    tape    in    same direction  as  you  would  tighten  a  nut.    Tape  must  be pressed into threads without cutting or ripping. CAUTION 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. (4) Using hand tools, tighten fittings to specified torque. 2-11
