How to change a A/C Compressor

to a Air Compressor

         1.  Get the brackets and compressor for the type used by the factory on your
         engine for AC.  Bolt all the brackets compressor.  Install the belts to the stock
         configuration.
         2.  Connect the intake side to a clean air intake.  Either use your air filter, or
         a universal small engine type filter.
         3.  Connect the output side to a standard air compressor (110-120 volt switch)
         pressure regulator switch.  This can be mounted on the compressor or a remote
         tank or line on the high pressure side.  You can purchase one of these as a
         replacement from a hardware store, or Harbor Freight.  The price for this will
         run you about $25-30.
         4.  Bring in a 12v power from the positive side of the battery.  Use a 14 gage wire,
         or from a ignition switched side (best) Install a separate on-off switch in line
         before it goes to the pressure switch.  This can be inside the vehicle or under the
         hood.  You do not want to run the compressor when you don't need it.
         5.  Connect the electric clutch control wire (single wire from coming from the clutch
         on the compressor) to the other side of the pressure switch.
         6.  Bring the high pressure output side air to a tank or to a quick disconnect
         located at a easy to get location on your vehicle.
 
         Special Notes:

         GM Types (Frididgaire) with a small lump on one side. 
         Put this down at a position that you can get to.  This has a special bolt with 
         a O-ring on it, this is your oil access point.  With the system bleed of this 
         pressure, use motor oil.  (3-5 squirts of oil in the bolt hole).  This should be 
         done after every 2-3 hours of use.  It is good to also drop only 3-4 in the intake
         at the same time.
 
         The engine should not be running above 1,200 when used as a compressor.
         A hand control throttle will allow you to do this with out holding
         your foot on the gas.  The universal twist and lock type at Napa cost about
         $15-$18.  It is not necessary to go above an idle for airing tires.  If you want
         to run air tools a tank in line works best.
          York and other type.
         This can be mounted in any of the 3 sides.  Vertical is vest.  The York does
         not have the volume of air at a idle as the GM type the total pressure is
         way more than you can use.  The engine should not be running above 1,200
         when used as a compressor.  A hand throttle used to bring the speed up to
         about 900 to 1000 RPM's is best.  The universal twist and lock type at Napa
         cost $15-$18.  The center bolt in the middle of the case is the oil.
