BLEEDING AIR FROM POWER STEERING SYSTEMS
         
                  PLEASE FOLLOW AGR’s BLEEDING INSTRUCTIONS ONLY!
                  Do not start engine until system is fully bled.
         
         AGR has found that the following method is the only proper way to bleed a system.
         
         When to bleed.
          • After any component replacement.
          • If any part of system is opened for any reason.
         Why bleed:
          • To prevent pump damage.
          • To ensure proper system operation.
          • To stop steering system noise.
         Before bleeding:
            Inspect steering system.
          • Hoses must not touch any other part of vehicle. Steering system noise could
             be caused by hoes touching frame, body, or engine.
           • MLhoe~ eoumecliouiamust be tight. Loose connections might not leak but
             could allow air into system. Do not over tighten o-ring hoses as the n-ring
             might be crushed. Chock flare seat type connections for exact fit.
         How to bleed:
          • engine off:Do not stint .ngineuntilsyslcm is fullybleed or pump could be
         
          a.  Bai~ finututiiuls the ground, or leave pitman arm or tie rod off.
         
          • FlU SuldeUmrwo~ to “flaIl cold” level. Leave cap off. Use only power steering
            fluid. No transmission fluid.
          • With assistant checking fluid level and condition turn steering wheel lock to lock
            at least 20 times.
            o On systems with coolers, winches, Rock Ram assist you may need to cycle
              40 to 100 times.
            o Trapped sir may cause fluid to overflow. Thoroughly clean any spilled
              fluid to allow for leak check.
          • While turning wheel, check fluid constantly.
            o No bubbles are allowed.
                 For any sign of bubbles, recheck connections. Repeat above.
            o Fluid level should be steady (Rock Rams level will vary slightly).
          • Start engine. With engine idling, maintain fluid level. Reinstall cap.
          • Return wheels to center. Lower front wheels to ground or reinstall pissnan arm.
          • Start and run engine for two minutes. Turn steering wheel in both directions.
         •  Verify
            o Smooth power assist.
             n Noiseless operation.
            o Proper fluid level.
            o No system leaks
            o Proper fluid condition
                 No bubbles, no foam, no discoloration.
          • If all proper conditions apply, procedure is complete.
          • If any problem remains, turn off engine, do not drive, and see Special Conditions.
         Specisl Conditions:
          • Foam obubbles in fluid.
            o Fluid must be completely free of bubbles.
            o Fluid should not rise when engine is tamed off. (trapped sir)
            o Be alert to periodic bui,bles that could indicate a loose connection or leaky
              0-ring, or bad flare seat, in either the pressure or return hose.
         • Discolored fluid. (millcy, opaque, or light tan color)
           o Switch ignition off. Wait two minutes. Recheck hose connections. Repeat
              start up procedures. If problem still exists, replace or check possible cause.
               • Return hose clamps.
               • Return hose 0-ring or flare seat.
               • Pressure hose 0-ring or flare scat.
               • Any other connections.
               • Fill system and repeat bleed procedure for each possible cause.
         Noise:
          • Pump whine or groan. (after all air is out of system, if sf15 no~~out then ace
            Specisl Conditions)
           0 Check belts for slippage.
            o Mark pulley and make sure it is not slipping on shaft. -
           o With engine running, recheck hoses for possible contact with frame, body,
              or engine. If no contact is found, cool down fluid and repreasurizc system.
               • After cooling fluid, start engine to come up to operating
                 temperature. Recheck.
