TM 5-3895-374-24-2 Fig.  1-Assembly. NOTE: A    screw    conveyor    drive    consists    of    three    sub- assemblies listed below. 1. Reducer-Includes    speed    reducer,    shaft    retainer, retainer bolt and lockwasher. 2. Adapter Assembly-Includes adapter bolts, lockwashers,  a  lip  type  seal,  2  braided  type  seals and seal retaining ring. 3. Drive Shaft-Includes shaft and key Make certain none of the parts have been damaged in  shipment.    Any  shipping  damage  should  be  promptly reported   to   the   carrier.      Read   all   instructions   in   this manual   before   attempting   to   assemble   or   install   the Screw Conveyor Drive.  It is important that assembly be performed in the following sequence and that each step be completed before continuing to the next. ASSEMBLY 1. Place  reducer  on  blocks  so  that  it  lays  flat  with  the input shaft down. 2. Position adapter on reducer output hub so that small end (end with 12 holes) rests on reducer.  Select the 4  mounting  holes  to  match  the  shaft  used  (see  Fig. 1). 3. Place    adapter    screws    and    lockwashers    through adapter and thread into reducer.  Do not tighten. 4. Select either lip type or braided type seals and install as follows: Lip Type Seals.  Place seal in adapter so that spring faces  out.    Seal  should  be  tapped  evenly  into  place in  the  adapter  with  a  soft  hammer,  applying  force only   on   the   outer   corner   of   the   seal.      Fill   cavity between lips of seal with grease.  Install seal retainer ring  by  tapping  with  a  hammer.    Apply  grease   to adapter   section   of   shaft   (middle   section).      Slide shaft,  keyseated  end  first,  into  adapter  and  through reducer.    Note:    Be  extremely  careful  when  sliding adapter section of shaft through seal to prevent seal lips from being damaged or rolled over. Braided Type Seals.  Flatten both seals with a soft hammer.    Place  seals  in  adapter,  one  on  top  of  the other with joints offset from each other.  Lay retaining ring  loosely  on  top  of  seals.    Slide  shaft,  keyseated end  first,  into  adapter  and  through  reducer.    Take care to clear the seals with the adapter section of the shaft, Once shaft has bottomed, seat retainer ring by simultaneously    hitting    the    face    of    the    ring    on opposite sides of the shaft with two hammers. 5. Carefully  place  reducer  on  its  side.    Rotate  shaft  to align  keyseats  in  shaft  and  output  hub  and  install key.      Install   shaft   retainer,   lockwasher   and   bolt. Tighten bolt to torque specified in Table 4 on page 8. 6. Lay  reducer   on   blocks   with   input   shaft   down   and tighten  adapter  bolts  to  torque  specified  in  Table  4 on page 8. 7. If  waste  packing  is  to  be  used,  it  may  be  installed through access hole provided in the adapter.  Waste packing,   not   furnished   with   screw   conveyor   drive, may    be    used    as    a    separate    seal    option    or    in combination with either the lip or braided seals. INSTALLATION 1. Determine    the    running    positions    of     the     screw conveyor drive.  Running positions are shown in Fig. 2.  Note that the reducer is supplied with  7  plugs;  5 around    the    sides    of    the    reducer    for    horizontal installations     and     1     on     each     face     for     vertical installations.  These plugs must be arranged relative to the running positions as follows: Horizontal  Installations-Install  the  magnetic  drain plug in the hole closest to the bottom of the reducer. Throw away the tape that covers the filler/ventilation plug in shipment and install plug in topmost hole.  Of the  3  remaining  plugs  on  the  sides  of  the  reducer, the lowest one is the minimum oil level plug. Vertical Installations-Install the filler/ventilation plug in  the  hole  provided  in  the  top  face  of  the  reducer housing.    Use  the  hole  in  the  bottom  face  for  the magnetic  drain  plug.    Of  the  5  remaining  holes  on the  sides  of  the  reducer,  use  a  plug  in  the  upper housing half for the minimum oil level plug. WARNING To ensure that drive is not unexpectedly    started,    turn    off    and lock  out  or  tag  power  source  before proceeding.  Failure to observe these precautions    could    result    in    bodily injury. page 3-789
