Does anyone out there in Mercedes land know the measurement for the air gap on a R4 A/C clutch? My daughters car('85 300D)compressor has excessive air gap on the clutch and sometimes won't engage.

0.5- 1.0 mm. by the book. About the thickness of an old credit card by the shady tree.

Thanks... My gap sure isn't 1mm. It's more like 2.5 to 3mm. No wonder it has trouble engaging. Thanks Again!! CHris
