TRUCK SERVICE MANUAL TM 5-4210-230-14&P-1 STEERING GEAR LOST MOTION AT STEERING WHEEL 1.    Loose    ball    socket    connections    or    other    linkage connections. 2.    Loose steering gear adjustment Side cover adjustment and/or worm adjustment. 3.    Steering wheel loose on shaft. 4.    Pitman arm loose on output shaft. 5.    Steering gear loose on frame. 6.    Loose   connections   between   steering   column   and steering gear. EXCESSIVE HEAT 1.  Restriction in pressure or supply line due to severe bend,  kink,  or  clogging  by  dirt,  sludge,  or  other  impurities. Should  be  accompanied  by  high  back  pressure.  2. Undersize line, hose or fitting. 3.  Vehicle overloaded causing   pump      relief   valve   to   operate   excessively during  docking  or  other  maneuvers.  4.    Poppets  not properly  adjusted  to  relieve  pressure  at  full  turn  in each direction. 5.  Overheating can damage seals in both pump  and steering gear. 6.    Overheating  may  be  evidenced  by  seals  becoming  hard, discoloration   of   internal   parts   of   the   gear   and   an offensive odor from the hydraulic fluid. "TIPS" FOR MAINTENANCE OF STEERING GEAR SYSTEMS 1.      Always   check   for   wear   in   steering   linkage   and   other system components first, before making adjustments to steering gear assembly. 2.    Prevent  internal  bottoming  of  steering  gear  .    .    . Carefully check axle stops. 3.    Make  periodic  checks  of  lube  level  for  steering  gear and    components    to    prevent    malfunction    due    to inadequate lubrication. 4.    Make routine and/or periodic checks for proper front end alignment. 5.    Maintain correctly inflated tires. 6.    Always use a "puller," never use a torch or hammer to remove steering arms. 7.    Always   carefully   examine   all   steering   parts   which have  been  subject  to  "impact"  and  replace  any  that are questionable. 8.    Investigate   immediately,   and   correct   cause   of   any play,  rattle,  or  shimmy  in  any  part  of  the  linkage  or steering mechanism. 9.    Remove cause of steering column misalignment, and if necessary elongate support bracket holes at dash. 10.    Encourage  all  drivers  to  report  any  malfunction  or accident    that    could    have    damaged    the    steering mechanism. II.    Do     not     attempt     to     weld     any     broken     steering component.  (Replace only with original equipment.) 12.    Do  not  cold  straighten,  hot  straighten  or  bend  any steering system part. 13.    Always  use  new  seals  and  "O"-rings  during  repairs and overhauls. 14.    Replacement  of  single  bearing  assemblies,  or  balls, if one or more make a "set" is not recommended. 15.    Excessive   heat  will   develop   if   any   power   steering gear  is  held  in  an  extreme  right  or  left  turn  longer than  a  few  seconds.    (Heat  developed  can  damage seals and/or pump.) 16.    Prevent     dirt     or     foreign     particles     from     entering hydraulic    steering    system's.        (Always    clean    off around   filler   caps,   before   removing   to   check   oil supply.) 17.    Use  care  to  prevent  even  minor  hydraulic  leaks  to continue.
