a/c comp. sounds like shaking a spraypaint can. rebuildable?84 244gl 200 1984

Hi Kenneth,

B.C.'s experience with the York mirrors mine. If you would change the belt, you'd discover how it is adjusted, using shims between the split sheaves on the crank pulley that are stored in front of it.

The noise, which I'd have bet money was inside the compressor, was apparently the loose belt slapping in and out of the pulley groove under the York's considerable load... or some other physical phenomena related to the loose coupling.

The one in my 84 is still running R12, but much more quietly now that I've removed one of the shims. If you propose to do this, be aware it is easy to damage the sheaves by improper re-tightening of the six M6 fasteners; you must take care to do it slowly and evenly, while working the belt to the outer circumference by hand-rotating the crank bolt.

I've never seen a can that directed you to turn it upside-down, but fact is, I haven't looked at many lately. The way I recall, they were labeled "upright for gas, invert for liquid".
