TM 55-4920-328-13 2-48.  Installation of Power Absorption System. Install the T74 power absorption system as shown in figure 2-42, observing the following: a.    Assemble  the  packing  (3)  on  the  oil  plug  (4) and insert the assembled parts into the shaft (5). b.    Attach  the  hooks  of  the  sling  assembly  (1)  to the  shackle  assemblies  on  the  water  brake  assembly (2). c.  Install the torque element assembly (6) on the water brake assembly (2) with the torque element cable assembly    in    the    9    o'clock    position.        Secure    the installation  using  eight  washers  (7)  and  eight  bolts  (8). Tighten and lockwire the bolts. d.    Use  a  suitable  hoist  to  lift  and  position  the water brake assembly (2) on the end flange of the shaft (5). e.    Install  eight  bolts  (9),  16  washers  (10),  and eight  nuts  (11)  to  secure  the  water  brake  assembly  (2) on the shaft (5).  Tighten and lockwire the nuts. f.  Install the torque stub shafts (12) two places on the  torque  element  adapter  (13),  using  eight  washers (14) and eight bolts (15). g.  Ensure that the slot in the adapter (13) is in the 9  o'clock  position,  then  attach  the  parts  assembled  in the preceding step to the aft face of the torque element assembly  (6),  using  12  washers  (16)  and  12  bolts  (17). Tighten and lockwire the bolts. h.    With  the  slot  in  the  torque  stand  plate  (18)  in the 9 o'clock position, insert the retainer (19) through the upper slot in the plate, align and position the retainer on the upper torque stub shaft (12), and install the bolt (20). i.      Align   and   position   the   second   retainer   (19) through the lower slot in the torque stand plate (18) on the  lower  torque  stub  shaft  (12)  and  install  the  second bolt  (20).    Tighten  and  lockwire  the  upper  and  lower bolts. j.    Position  the  torque  mount  plate  (21)  on  the frame of the engine test dolly assembly (28) and install six   bolts   (22),   12   washers   (23),   and   six   nuts   (24). Tighten the nuts securely. k.    Align  the  holes  in  the  torque  stand  plate  (18) with the upper attaching holes in the torque mount plate (21)  and  install  eight  bolts  (25),  16  washers  (26),  and eight nuts (27).  Tighten the nuts securely. I.    Release  the  tension  from  the  sling  assembly (1),  then  remove  the  sling  assembly  and  hoist.    2-49. Installation  of  T74  Engine  Accessories.    Install  the  T74 engine  accessories  as  shown  in  figure  2-43,  observing the following: NOTE When    required,    remove    the    engine shipping  covers,  plugs,  caps,  and  all attaching parts to facilitate installation of  the  engine  accessories.    Stow  the removed  parts  in  a  convenient  place for reinstallation after engine test.
