TM 55-4920-328-13 CAUTION • Never allow fuel or oil to contact electrical connectors. • Do not use pliers on electrical lead connectors. (10) Ensure that     all     unconnected     hoses, engineports,  and  cable    assemblies  are  capped  at  all times to prevent contamination. b.  Prepare  the  engine  test  dolly  assembly for the T700 METS Test Adapter as follows: (1)  Detach  the  mount  stand  assembly (2, figure  2-52)  by  removing  four  nuts  (3),    four  washers (4), and four bolts (5). (2)  Attach  the  hook  of  a  suitable hoist to the ring bolt (6) and remove the mount stand assembly (2) from the test dolly frame assembly (1). (3) Store the mount stand assembly (2) and all attaching parts in a convenient area for reinstallation on the test dolly frame assembly (1) after completion of engine test. c.    Install  the  support  frame  (1,  figure  2-53)  as follows: (1)  With  another mechanic  assisting, lift support  frame (1)   high   enough   to   position   it over test dolly (2). (2)  Maintaining  support  frame  (1) in level position, lower it onto test dolly (2), so that five boltholes are exposed on aft end of test dolly (see figure 2-53). (3)    Align    boltholes    in  support  frame  (1) with boltholes in test dolly (2). (4)  Install eight screws   (3), eight washers   (4), and eight nuts (5). Torque nuts to 420-510 inch-pounds. d.  Assemble  water  brake,  torque element, and mount assembly as follows: (1)  Place torque  element  (7, figure 2-54), aft  end  up,  onto  suitable  fixture.      Aft  end  has  strain gage cable (14) attached to it. (2)      Insert   water   brake      (6),   forward   end down, inside of torque element (7). (3)  Rotate torque  element  (7) until torque element  cable  is  at  9  o'clock  position  and  word  TOP (marked on water brake) is at 12 o'clock position. (4)  Assemble  adapter  (12)  to  water  brake (6).      Align  the  word  TOP  marked  on  adapter,  with  the word TOP marked on water brake.   Secure adapter to water  brake  with  eight  bolts  (10)  and  eight  nuts    (11). Torque    nuts    to    480-570  inch-pounds.    Lockwire  nuts and bolts. WARNING Torque element (7) is heavy and will drop if    not    supported    when    bolts    (13)    are removed.        When    element    has    to    be supported or lifted, at least two mechanics   will   be   required   in   order   to avoid personal injury. (5)  Raise  torque element          (7)     up     to adapter  (12).   Make sure   strain      gage   cable   (14) goes  into  cutout  of  adapter.    Secure  torque  element  to adapter  with  12  bolts    (13).  Torque  bolts  to  480-570 inch-pounds.  Lockwire  bolts together. e.    Disassemble  bracket    (1),  backplate  (2),  and housing (3) as follows: WARNING Due  to  its  weight,  disassembly  of  water brake and torque element mount assembly will require at least two mechanics   in   order   to   avoid   personal injury.
