    Hayes manual refuses to deal with the AC ( European Version) other
    than sensors and those parts inside the passenger compartment. The
    clutch replacemen t should not effect the refrigeration circuit.

    Are special tools required to change the AC compressor clutch. How
    long should the job take?

    Thanks. Advice greatly appreciated.

  2. Don't know what you mean by the term "AC (European Version) but on my 86
    Turbo Diesel which has a Sankyo 510 compressor not the Delco one, the
    assembly is removed with a three stud pulley remover. Never did this myself
    but it may be difficult to do this on the car. A simpler job if the
    compressor is on the bench. Bill

    You have to remove the bolt in the center of the clutch assembly, and a
    puller to pull the clutch off. It uses 3 bolts (6 mm) that go through
    the outside piece of the clutch. Then you find out the steel of the
    bearing is hopelessly seized onto the aluminum hub of the compressor.
    Then you can finally unscrew and remove the electromagnet windings.
    When you reassemble, make sure that you use the shims to set the gap
    between the 2 clutch surfaces properly.

    Estimated time: 30 minutes if you have the right tools and there's no
    seizing on up to forever.

    MIke, does it require removal of the grille and radiator? I meant
    the European version of the Haynes Manual ( not European AC) Sorry.
