    My the A/C compressor on my Ferrari 412 has failed.

    Can someone recommend a place to get this rebuilt or perhaps a cross reference with US cars?

    I believe it is a York model that was available on many cars, or should I upgrade to another compressor type?

    Thank you

    YORK ER210R

    This being said, the original aspera compressors are easy to fix, but are not compatible with york parts, they need special gasket and seals that are sold on ebay.

    Thank you. How do I know if I have a York or Aspera compressor?

    Aspera uses metric fittings, York uses imperial bolts. Also the yorks to have a dust screen in front of the shaft seal (geen in my photo). The head is also different: Aspera is more square while the York is more hexagonal (red in the photo)

    These are almost a direct swap, except for the retaining bots that you have to change.

    Great. Can this one be bought or do you suggest to get it rebuilt?

    It seems the main issue will be with clutch and pulley, seems Ferrari has a special pulley size.

    About 30 years ago I replaced my original York 209-U compressor. This compressor has flange fittings on top, not the screw fittings which most versions now have (see photo above). The exact replacement at that time was a Climate Control 488-16763. I also had to purchase square O-rings for the flange fittings. The valves on the flanges allowed me to isolate the rest of the system bofore removing them from the compressor to prevent air from entering the hoses, dryer, and evaporator. I did not replace the dryer which is usually recommended. An A/C shop did the recharge for me with R-12. They pulled a vaccum on the entire system for about 15 minutes before adding the R-12. The vacuum helped remove some water vapor from dryer. The A/C continues to work fine today.

    York no longer makes compressors. A Google search indicates Climate Control also no longer exists; this was new name of the old York plant in Decatur, IL. The next best option is to have your compressor rebuilt; there are several companies that can provide this service.

    The stock fittings are "rotalocks".

    In ER210R there is on R for reverse rotation and one for Rotalock. So any ER210R is fine be it from CCI, valeo, etc...

    There seems to be tons of ER210R compressors available online for not much.

    Is there a definitive way to test the clutch? If the clutch is good, then it would be cheaper and faster to get a brand new compressor.

    These compressors are fine. The clutch is indeed the specific part so as long as it works you will be fine.

    In order to test the clutch, while the pulley is still bolted on the compressor, you just apply 12v to the loose green cable. This is supposed to lock the pulley against the axle. From then on if you rotate the pulley, you can feel that you turn the axle of the compressor (there are two pistons in the compressor, so rotation does require a bot of force).

    If it does not lock you have to salvage parts from other pulleys that are not reverse rotation and find a way to fix the original one.
