VI.  TRANSFER CASE ASSEMBLY A.  General Precautions 1. Read  these  instructions  completely  before   starting reassembly.  Refer to the appropriate exploded view (at  the  back  of  the  manual).    Assemble,  adjust  and check in the order shown. 2. Parts must be clean.  Gasket surfaces must be free of old gasket material. 3. Select  an  area  that  will  maintain  the  cleanliness  of the parts and the assembly.  Mount the case housing with  the  cover  on  top,  cover  surface  in  a  horizontal plane.  The cover side, the front and rear of the case should    be    accessible.        The    housing    must    be restrained.    The  cover  should  be  approximately  44" above  the  floor.    A  sturdy  work  bench  (preferably between 24" and 28" high) or a special stand should be  used.    The  components  of  this  transmission  are heavy   and   positioning   and   installing   them   will   be easier    if    the    case    is    supported    in    the    position indicated, refer to Fig.  1 and Fig.  2. 4. Lubricate   housing   bores,   shaft   spline   and   bearing mounting   surfaces,   sealing   lips   on   oil   seals   with Lubriplate or equal.  This is necessary to reduce the chances  of  galling  or  scoring  and  to  provide  initial lubrication for the oil seals.  Use flanged end bearing drivers that apply equal force to both inner and outer races of bearings when installing bearings. 5. If tubular or sleeve type drivers are used, apply force to   either   inner   or   outer   race   or   both   as   needed, depending   on   which   will   put   the   bearing   in   place without pushing through the bearing balls. 6. Installation of gaskets, bearing carriers, seal carriers and  caps  will  be  simplified  if  two  guide  studs  are utilized (See Fig.  17).  Guide studs may be made by cutting the head off a 7/16-14 bolt of about 2 inches in length.  Point  the  non-threaded  end  and  also  slot the    end    to    allow    a    screwdriver    to    be    used,    if necessary, for guide removal. 7. Universal  joint  yokes  or  companion  flanges  should be coated with Lubriplate on the seal operating area before  installation.    They  should  be  tightened  into place with the locknuts tightened to the proper torque before the cover is installed on the case and before the  shim  thickness  is  determined  for  both  the  input shaft and the rear output shaft.  Universal joint yoke or companion flange retaining nuts can be tightened or loosened most easily when all components except shift forks are in place.  At that time it is possible to engage   both   the   direct   drive   and   the   underdrive clutch gears and effectively lock all the shafts against rotation. 8. Use  Permatex  Form-A-Gasket  #2  or  equal  pliable setting  sealant  on  bolt  threads.    If  bolt  threads  are not sealed they will leak oil. Fig. 8 B.  Seal Carrier Assemblies Seals  supplied  by  Fabco  are  coated  on  the  outside and    should    not     be     coated     with     Permatex     before installation  in  their  carriers.    They  should  be  coated  on the  sealing  lip  with  Lubriplate.    Installation  can  best  be made   with   an   arbor   press.      There   are   three   or   four input/output  shaft   seals   and,   if   a   mechanically   shifted case,    two    or    three    shifter    shaft    seals,    the    quantity depending on whether the case does or does not have a PTO assembly installed. C.  Clutch Gear and Bearing Assemblies Apply Lubriplate to the bearing bores of each of  the three  clutching  gears.    Press  the  bearings  into  place  by applying force to the outer bearing race.  Be sure to put the   spacer   ring   in   place   before   installing   the   second bearing  in  35  tooth  clutching  gears  (Item  22  on  input shaft and Item 12 on front output shaft). -16-
