Troubleshooting Guide NOTE:  Before  troubleshooting  any  system  problem,  check  service  literature  published  by  the equipment  and/or  component  manufacturers.    Follow  their  instructions,  if  given,  for  checking any component other than the MAB or MAE Torqmotor Ô   unit. Preparation Make    your    troubleshooting    easier    by    preparing    as follows: work in a clean, well-lighted-place; have proper tools and materials nearby; have an adequate supply of clean petroleum-based solvent. WARNING: SINCE THEY ARE FLAMMABLE, BE EXTREMELY CAREFUL WHEN USING ANY SOLVENT. EVEN A SMALL EXPLOSION OR FIRE COULD CAUSE INJURY OR DEATH. WARNING: WEAR EYE PROTECTION AND   BE   SURE   TO   COMPLY   WITH OSHA    OR    OTHER    MAXIMUM    AIR PRESSURE REOUIREMENTS. Preliminary Checks Hydraulic  systems  are  often  trouble-free.    The  problem an operator complains of could be caused by something other than the hydraulic components. Thus, once you have determined that a problem exists, start with the easy-to-check items, such as: parts  damaged  from  impact  that  were  not  properly repaired, or that should have been replaced; and improper    replacement    parts    used    in    previous servicing mechanical    linkage    problems    such    as    binding, broken, or loose parts or slipping belts. Hydraulic Components If   you   think   the   problem   is   caused   by   a   hydraulic component, start by checking the easy-to-reach items. Check all hoses and lines for cracks, hardening, or other signs   of   wear.      Reroute   any   useable   hoses   that   are kinked,  severely  bent,  or  that  rest  against  hot  engine parts.      Look   for   leaks,   especially   at   couplings   and fittings.    Replace  any  hoses  or  lines  that  don't  meet system flow and pressure ratings. Next, go to the reservoir and filter or filters.  Check fluid level  and  look  for  air  bubbles.    Check  the  filter(s).    A filter with a maximum 50 micron filtration is recommended for the MAB and MAE system. Visually   check   other   components   to   see   if   they   are loosely mounted, show signs of leaks, or other damage or wear. Excessive    heat    in    a    hydraulic    system    can    create problems that can easily be overlooked.  Every system has its limitation for the maximum amount of temperature.      After   the   temperature   is   attained   and passed, the following can occur: oil seal leaks loss of efficiency such as speed and torque pump loss of efficiency pump failure hoses become hard and brittle hose failure A     normal     temperature     range     means     an     efficient hydraulic  system.    Consult  the  manuals  published  by equipment and/or component manufacturers for maximum   allowable   temperatures   and   hydraulic   tests that may be necessary to run on the performance of the hydraulic   components.      The   MAB   and   MAE   are   not recommended   for   hydraulic   systems   with   maximum temperatures above 200 °F (93.3°C). 1A
