(40)  When a T55-L-7 engine is to be tested, install the T55-L-7 torque indicator (2, figure 2-7) in accordance with the instructions outlined in paragraph 2- 7.  Connect P5 of the branched cable assembly (10) in operator's  panel  3A1  to  the  mating  connector  on  the torque indicator. (41)    When  a  T55-L-11/712  engine  is  to  be  tested, install  the  T55-L-11/712  torque  indicator  (3,  figure  2-7) in accordance with the instructions outlined in paragraph 2-7.        Connect    P6    and    P7    of    the    branched    cable assembly   (10)   to   the   appropriate   connectors   on   the torque indicator. (42)    When  a  T55-L-11/712  engine  is  to  be  tested, connect P8 of the branched cable assembly (10) to the mating connector on the inverter (6). 2-31.  Installation of Power Absorption System. Install the power absorption system as follows: a.    Remove  the  bellmouth  (8,  figure  2-30)  from  the torque system assembly. a1.      Install   nipple   (10)   in   water   brake   aft   bearing supply port. a2.  Install nipple (11) in water brake oil return port. b.  Remove the torque element shaft (12, figure 2-28) from the torque system. c.        Apply    molybdenum    disulphide    conforming    to Specification  MIL-M-7866  to  the  internal  splines  of  the torque element shaft. d.    Install  the  torque  element  shaft  onto  the  adapter (11) on the aft end of the water brake. e.  Guide  the torque  element  oil drain tubing through a  hole  in  the  water  brake  adapter  plate  and  secure  the water  brake/torque  system  assembly  with  12  bolts  (8) when  testing  T55-L-11/712  engines  or  12  bolts  (9)  and spacer  (10)  when  testing  T55-L-7/7C  engines.    Tighten and lockwire the bolts. NOTE Spacer  (10)  must  be  installed  when testing T55-L-7/7C engines and must be    removed    before    testing    T55-L- 11/712 engines. f.    Install  the  barlift  (3)  on  the  water  brake  with  bolts (4) and washers (5). g.      Use   a   suitable   hoisting   device,   lift   the   water brake/torque   system   and   suspend   the   assembly   at   a convenient height forward of the test engine.
