88 740 : How to change AC compressor clutch.

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.

 

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.
