TM 55-4920-328-13 (1) Follow procedures in Chapter 2, paragraph  2-70  for  removal  of  engine,  support  frame, and hardware. (2) Attach  suitable  hoist  to  eyebolt  (1,  figure 6-16). (3) Remove two thermocouples (4). (4) Remove  four  bolts  (2)  and  pull  plate  (3) forward. CAUTION Be   careful   not   to   damage   cable (12) during removal of water brake and torque element. (5) Remove water brake and torque element. Place  it  on  a  suitable  fixture,  aft  end  down.  Remove hoist. (6) Remove    four    bolts    (5).    With    another mechanic, lift water brake, torque element and mounting ring  (14)  from  housing  (6),  sliding  cable  (12)  through housing opening. (7) Place  water  brake,  torque  element,  and mounting ring aft end down.  Remove 12 bolts (15) and mounting ring (14). (8) Turn    water    brake    and    torque    element forward end down. WARNING Removing Torque Element Torque  element  (13)  is  heavy  and  will drop  when  bolts  (7)  are  removed.  Use two    mechanics    when    removing    to avoid injury to personnel. (9) With another mechanic supporting torque element  (13),  remove  bolts  (7).    Carefully  lower  torque element. (10) With   another   mechanic,   remove   water brake (8) with torque element plate (11). (11) Remove eight bolts (10) and nuts (9). (12) Remove plate (11). b. Disassembly and Bearing Inspection. (1) Remove lockwire from six bolts (1, figure 6-17). Remove these bolts and their six seals (2). (2) Remove manifold (3) with fittings (4, 5, 6 and 7) installed. (3) Remove   outer   housing   (8)   and   bearing sleeve (10). (4) Using a standard commercial micrometer, measure  and  record  the  outside  diameter  (OD)  of  the bearing journal of rotor assembly shaft (11). (5) Using    a    standard    commercial    caliper, measure   and   record   the   inside   diameter   (ID)   of   the bearing sleeve (10). (6) The  difference  in  diameters  (bearing  ID minus shaft OD) must be between 0.003 and 0.008 inch (0.0762  and  0.2032  mm).  If  the  difference  is  not  within these limits, install a new bearing sleeve (10). c. Reassembly. (1) Clean  and  lubricate  parts  in  accordance with paragraph 6-58. (2) Install   new   preformed   packings   (9)   on manifold (3) and forward thrust bearing assembly (12). (3) Install outer housing (8). (4) Install  manifold  (3)  with  fittings  (4,  5,  6 and  7)  and  install  six  bolts  (1)  and  seals  (2).  Torque bolts to 250-325 inch-pounds and lockwire them.
