TM 55-4920-328-13 WARNING Handling Bladed Components Wear leather palm gloves (welder's type with gauntlet) when handling components with assembled     blades     and     vanes. Blades  and  vanes  are  sharp  and can cause serious injury. (7) Insert torque shaft (9) into output shaf spline.  If necessary,  rotate  power  turbine  rotor  by  hand  to  align spline of engine output shaft with spline of torque shaft. CAUTION Torque   shaft   (9)   must   be   fully seated into output shaft. Otherwise, later engine installation can damage the shaft. (8) Gently  useup-and-down  and  sideto-side  motion to fully seat torque shaft (9) into output shaft. (9) Lightly lubricatewater brake spline (11) with anti- seize compound MIL-A-138818 (see table 1-8). 2-64.  Installation of Engine into Support Frame. a. Place  bellmouth  (3,  figure  2-56)  behind  rabbet (14) of water brake torque element. CAUTION Keep    engine  parallel    to  support frame    to    prevent    damage    from incorrect     contact     with     adapter components. b. With  another  mechanic  maintaining  engine  in level  position,  carefully  lower  engine,  and  align  torque shaft (9) with water brake spline (11). WARNING Handling Bladed Components Wear          leather     palm          gloves (welder's type with gauntlet) when handling components with assembled     blades     and     vanes. Blades  and  vanes  are  sharp  and can cause serious injury. c. Carefully   move   engine   forward.      It   may   be necessary to pull mount for water brake torque element assembly forward slightly to install engine.  Insert torque shaft (9) into water brake spline (11).  Make sure torque tube  mount  (6)  is  seated  inside  rabbet  (14)  of  torque element.  Thread five screws (5) into torque tube mount. Torque screws to 420-510 inch-pounds. d. With second mechanic slightly expanding clamp (2),  assemble  bellmouth  (3)  to  swirl  frame  flange  (1). Secure bellmouth with clamp. e. Torque  nut  of  clamp  (2)  to  80-85  inch-pounds. Install clip (10) into clamp (2). f. Align  linkages  (5  and  6,  figure  257)  to  diffuser case   support   lugs   (7).      If   necessary,   raise   or   lower engine to align linkages with diffuser support lugs. g. Install two bolts (14) (boltheads forward) through linkages  (5  and  6).    Thread  two  nuts  (8)  onto  bolts. Torque nuts to 480-570 inch-pounds. h. Slide inlet fairing (15) forward.  Insert studs (16) through  boltholes  in  housing  of  water  brake  and  torque element mount (17). i    Threa nuts (18) onto studs (16).  Torque nuts to 160-210 inch-pounds.
