EQUALIZING BEAM SUSPENSION (HENDRICKSON) Tube Type Beam End Mounting, RS 500 and RT 500 only, Figure 5 a. Apply  a  light  coat  of  IH-251H-EP  multi-purpose grease to outer diameter of end tubes. b. Align    the    beam    end    bushings    with    hanger brackets  and  insert  end  tubes.  Center  tubes  in bushings  so  that  ends  of  tubes  are  equidistant from outer faces of hanger brackets. c. Install    end    tube    nuts.    Make    sure    nuts    are properly  threaded  on  tubes.  Do  not  tighten  nuts at this time. Bolt Type Beam End Mounting, Figure 4 a. Align  beam  end  bushings  with  hanger  brackets and insert  bushing  adapters.  Lubricate  adapters with   a   light   coat   of   IH-251H-EP   mutli-purpose grease.   Flat   surface   on   adapters   must   be   in vertical position. b. Tap  adapters  into  bushing  until  adapter  flanges contact outer faces of hanger brackets. c. Install bolt and locknut. Do not tighten nut at this time. Bolt    Type    End    Mounting    with    Split-Ring    Type Adapters, Figure 4 a. Place inner adapter (with split-ring)  inside  beam end bushing with grooved end of adapter toward bowl  of  axle  housing.  Lubricate  adapter  with  a light  coat  of  IH-251H-EP  multi-purpose  grease. Make sure nut is in position in lugs of adapter. b. Align  beam  end  bushing  with  hanger  brackets and install outer adapter. c. Start   bolt   through   outer   adapter,   push   inner adapter with bolt until groove in adapter appears past face hanger. d. Install   split-ring.   Thread   bolt   into   nut.   Do   not tighten   bolt   to   specified   torque   at   this   time. When  bolts  are  torqued  after  torque  tools  are installed,  place  a  bar  between  the  lugs  on  the adapter  to  hold  the  nut  while  tightening  the  bolt with a wrench. Ball and Socket Beam End Bushing Type  Mounting, Figure 10 Assemble    ball    and    socket    beam    end    bushing    type mounting  as  shown  in  Figure  10.  Do  not  tighten  nuts  at this  time.  Repeat  same  procedure  at  opposite  end  of beam. CAUTION   --   WHEN   REINSTALLING   THE   "RUBBER BUSHED" EQUALIZING BEAMS TO THE AXLES AND SADDLES, DO NOT TIGHTEN NUTS UNTIL TORQUE RODS   ARE   INSTALLED   AND   EQUALIZING   BEAMS ARE LEVEL WITH THE FRAME. (THIS IS TO ASSURE THAT   THE   RUBBER   IS   IN   A   NEUTRAL   POSITION, ELIMINATING    THE    POSSIBILITY    OF    TORSIONAL WIND-UP,    WHICH    MAY    AFFECT    RIDE    QUALITY.) THEN    TIGHTEN    ALL    NUTS    TO    RECOMMENDED TORQUE (SEE SPECIFICATIONS) Place   one   end   of   cross   tube   into   center   sleeve   of installed equalizer beam. Be sure tube seats into sleeve. Assemble    other    equalizer    beam    to    cross    tube    and position beam in spring saddle. 3. Roll axle assemblies with equalizer beams under center  of  saddle.  Make  sure  the  outer  bushings are lined up with center of the saddle legs. 4. Lower vehicle frame centering saddles on beam end bushings. 5. Install  saddle  cap  and  nuts.  Do  not  tighten  until torque  rods  are  installed  and  equalizer  beams are level with frame. Torque nuts to recommended torque. Refer to SPECIFICATIONS. The cross center tube is free to rotate or float in the bushing assemblies at each side.  However, in   some   cases   where   the   vehicle   has   been operating  in  mud  or  perhaps  water,  the  cross center tube may be seized. Whether it is loose or seized will have no effect upon its purpose. The function    of    the    tube    is    to    assure    alignment between the left and right equalizer beams. The   saddle   caps   serve   to   secure   sleeve   with bushing.        The    clamping    effect    of    the    caps against  the  sleeve   and   bushing   has   no   effect upon the movement of the cross center tube.
