TM 55-4920-328-13 (2) Remove   the   match-numbered   bolts   (4) and   nuts   (5)   from   the   flexible   coupling   (22)   sleeves. Slide  the  sleeves  from  the  hubs  onto  the  water  brake and flywheel shafts.  Remove the flange O-ring from the female sleeve of the flexible coupling. (3) Remove   the   lockwire,   then   remove   the bolts  (6)  and  washers  (7)  securing  the  front  and  rear pillow    blocks    (8,    9)    to    the    frame    assembly    pads. Remove the flywheel (10) and pillow blocks as a unit. (4) Remove   the   hub   and   sleeve   from   the flywheel assembly (10) shaft as follows: (a)    Remove  the  hub  packing  from  the sleeve;   position   the   sleeve   and   packing   against   the flywheel. (b)    Loosen the setscrew on the flexible coupling hub. (c)    Place  the  flywheel  assembly  in  an upright position. (d)    Surround   the   forward   end   of   the flywheel assembly shaft and hub with dry ice.  Allow the dry   ice   to   remain   around   the   shaft   and   hub   for   a minimum of two hours. (e)    Pour SAE 10 weight motor oil into a pan  to  a  depth  sufficient  to  cover  the  flexible  coupling sleeve   and   the   plate   of   the   LTCT10543-01   flexible coupling puller. (f)    Raise  the  temperature  of  the  oil  to approximately 260°F (127°C). Note The     following     steps     must     be performed as quickly as possible. (g)    Remove    the    dry    ice,    slide    the sleeve  over  the  hub  and  attach  the  plate  only  of  the flexible  coupling  puller  to  the  sleeve.    (Use  coupling bolts.) (h)    Immerse the puller plate and sleeve into  the  heated  oil  for  a  period  of  from  three  and  one- half to four minutes. (i)    Remove the puller plate and sleeve from  the  oil  and  insert  the  puller  jacking  screw  into  the puller  plate  and  remove  the  sleeve  and  hub.    Remove the hub O-ring and key. (5) Loosen   the   setscrews   and   remove   the pillow   blocks   (8,   9)   from   the   flywheel   assembly   (10) shaft. (6) Properly support the water brake assembly (12).  Remove the lockwire, then remove the bolts  (11)  securing  the  water  brake  assembly  >  to  the torque    element    body.        Remove    the    water    brake assembly. (7) Remove   the   hub   and   sleeve   from   the water brake assembly (12) shaft as follows: (a)    Remove  the  hub  packing  from  the sleeve;   position   the   sleeve   and   packing   against   the water brake housing. (b)    Loosen the setscrew on the flexible coupling hub. (c)    Place  the  water  brake  in  an  upright position. (d)    Surround   the   forward   end   of   the water brake shaft and hub with dry ice.  Allow the dry ice to  remain  around  the  shaft  and  hub  for  a  minimum  of two hours. (e)    Pour  SAE  No.    10  motor  oil  into  a pan  to  a  depth  sufficient  to  cover  the  flexible  coupling sleeve   and   the   plate   of   the   LTCT1054301   flexible coupling puller. (f)    Raise  the  temperature  of  the  oil  to approximately 2600F (1270 C). Note The     following     steps     must     be performed as quickly as possible. (g)    Remove    the    dry    ice,    slide    the sleeve  over  the  hub  and  attach  the  plate  only  of  the flexible  coupling  puller  to  the  sleeve.    (Use  coupling bolts.) (h)    Immerse the puller plate and sleeve into  the  heated  oil  for  a  period  of  from  three  and  one- half to four minutes. (i)    Remove the puller plate and sleeve from  the  oil  and  insert  the  puller  jacking  screw  into  the puller  plate  and  remove  the  sleeve  and  hub.    Remove the hub O-ring and key. (8) Straighten   the   tabs   of   tabwasher   (14), then   remove   the   bolt   (13)   and   tabwasher   from   the adapter (15).  Remove the adapter. (9) Properly     support     the     torque     element assembly (17).  Remove the lockwire, then remove the bolts    (16)    securing    the    torque    element    assembly. Remove the torque element assembly. 6-35
