TM 5-3895-374-24-2 5.  Mesh output hub and countershaft together and place in  housing  half.    Place  input  shaft  assembly  in  housing half.    Tap  lightly  with  a  soft  hammer.(rawhide  not  lead hammer)  until  bearings  are  properly  seated  in  housing. Make   sure   that   the   snap   rings   on   the   O.D.      of   the bearings come into contact with the housing. 6.      Clean   housing   flange   surfaces   on   both   halves, making sure not to nick or scratch flange face.  Place a new bead of gasket eliminator on flange face and spread evenly over the entire flange leaving no bare spots. 7.  Place housing half in position over dowel pins and tap with   a   soft   hammer   (rawhide   not   lead   hammer)   until housing  halves  are  together.    Install  housing  bolts  and tighten evenly.  The final wrench torque for housing bolts is listed in table 3.  Place output hub and on TXT 5A the input shaft bearing cup in other housing half.  Make sure cup is properly seated in housing. 8.      Install   the   output   hub   seal   carrier   and   the   shims removed   at   disassembly.      Tighten   carrier   cap   screws while rotating the output hub  to  make  sure  the  bearings do  not  bind.    If  the  bearings  start  to  bind,  add  more shims.    Torque  the  carrier  bolts  to  the  value  shown  in table  3.    Attach  an  indicator  to  the  housing  and  set  the gage on the top end of the output hub.  Insert a pry bar under the other end of the hub and force it upward.  The axial end play of the output hub will be given by the indicator reading.    Add  or  remove  shim  stock  to  attain  a  reading  of from  .001"  to  .003".    Remove  seal  carrier  and  place  a  1/8" diameter bead of Dow Corning RTV732 sealant on the  face around  the  I.D.    of  the  last  shim  (sealant  is  to  be  between shim and reducer housing).  Reinstall output hub seal carrier and tighten carrier screws to torque shown in table 3.  On the TXT 5A reducer input pinion use the same method to adjust the   bearings   as   used   for   the   output   except   the   bearing adjustment should be .002 to .003. 9.    Install  oil  seals.    Extreme  care  must  be  observed  when installing seals on input shaft and output hub to avoid contact with    any    sharp    edges.        This    danger    of    damage    and consequent  oil  leakage  can  be  decreased  by  covering  all sharp  edges  with  adhesive  tape  or  paper  before  installing seals.    Chamfer  or  de-burr  housing  bore  if  end  of  bore  is sharp or rough.  Fill cavity between lips of seal with grease. Seals  should  be  pressed  or  topped  evenly  into  place  with  a soft hammer (rawhide not lead hammer) applying force only on the outer edge of the seals.  A slight oil leakage may be evident at the seals during initial running in, but will disappear unless seals have been damaged. 10.    Reassemble  and  install  the  Screw  Conveyor  Drive  in accordance with the instructions in the front of this manual.
