TM 10-3930-671-24 Wheel Hub Assembly If you are unfamiliar  with  this  procedure,  please  refer  to Section  9.6,  Steer  Axle  Wheel  Bearing  Maintenance  for additional information. Refer to Section 11, page 11.0-2, for cushion steer wheel bearing cup nomenclature. 1. If bearings are to be replaced and bearing cups were    removed,    install    new    bearing    cups    by pressing or driving into place in wheel hub. Refer     to     Section     9.6,     Steer     Axle     Wheel     Bearing Maintenance. NOTE Keep   serviceable   bearing   cups   and cones    matched    together.        Always replace bearing cups  and  cones  as  a set. Recommended Greasing Procedure: 1) Use  Grade  No.    1  EP  Lithium  soap  base multi-purpose     grease,     Clark     MS-9B     or equivalent. 2) All tapered roller bearings to be packed with grease before assembly. 3) Tie rod bearings to be filled using a grease gun after axle is reassembled. 4) Apply  coating  of  Grade  No.    2EP  Lithium soap base multi-purpose grease, Clark MS- 107C or equivalent, to inside diameter of oil seals prior to assembly. 2. Pack   the   bearing   with   grease   and   install   the inner bearing in the hub. 3. Apply lubricant to and install new grease seal in wheel hub bore. See above for greasing procedure. 4. Install wheel hub on spindle. NOTE Be   careful   not   to   damage   seal   lip when moving the hub over the end of the spindle and threads.  Support the wheel    hub    to    avoid    dragging    the grease seal at the back side over the spindle. 5. First pack with grease and then install the outer wheel bearing. 6. Install    bearing    washer    and    nut    and    tighten spindle  (bearing  adjusting)  nut  until  there  is  a slight binding or drag in the bearings as wheel or hub is rotated by hand in both directions.  Then, back  nut  off  to  nearest  slot  in  nut  and  lock  with cotter pin.  Bend tabs on cotter pin. 7. Recheck    for    correct    bearing    adjustment    by rotating the wheel by hand.  Wheel should rotate freely    or    with    only    slight    "drag".        Readjust bearings  by  adjusting  spindle  nut  as  necessary to avoid binding in bearings. 8. Pack the area around spindle nut with grease. 9. Install  hubcap  by  tapping  into  place  with  rubber or plastic-faced hammer. 10. Install wheel and tire assembly on hub. 11 Install  wheel  mounting  lug  nuts.    Tighten  wheel mounting   nuts   to   torque   spec:   265-338   Ib-ft (359458 N•m). F439 (F-440 blank)
