Funola,

Do you know whether the compressor you are dissassembling is a mercedes specific R4. Check out the upside down email I posted where the R4 for GM is mounted correctly and the r4 for mercedes is bottom mounted.

check that oil slinger (I'm assuming it spins so the lateral orientation wouldn't matter)

There should be a path for oil to travel into the moving parts that is orientation specific.

Let us know.

Kent
