TM 10-3930-671-24 8. Stop  the  upright  when  the  first  tilt  cylinder  bottoms  out against its rod spacer. Use rod shims to fill in the space between   the   rod   end   and   spacer   on   the   opposite   tilt cylinder. NOTE Shown  is  a  standard  tilt  cylinder  with  spacer.  Uprights with MFH of more than [3912 mm] 154 in. use spacers to restrict back tilt. 9. After   the   excess   space   is   taken   up   by   the adjusting    shims,    retest    the    full    forward    and backward tilt for correct adjustment. Tilt Cylinder Removal Refer to tilt cylinder mounting illustration. NOTE To  perform  this  service  procedure,  it  is  recommended that you first: • Park truck on a level surface. • Put  the  upright  in  a  vertical  position  and lower the carriage fully down. • Return all controls to neutral and turn key switch OFF. • Apply   the   parking   brake   and   block   the wheels. 1.    Be  sure  all  hydraulic  attachments  are  secured and upright and carriage are in the fully-lowered position. 2.    If   both   tilt   cylinders   are   to   be   removed,   the upright    must    be    supported    by    use    of    an overhead chain hoist of adequate capacity. Attach a chain or sling to the upright and a hoist before removing any tilt cylinder or upright attachment parts.  Be sure  to  secure  and  support  upright  from  falling  before removing  tilt  cylinders.  Failure  to  secure  upright  could result in injury or death.
