Quick update - The compressor is back in the car as planned with the factory supplied shipping pads that seal in the SP-10 oil that Sanden put in during manufacture. I'm relieved that the pulleys line up well with no belt squealing. That wasn't a certainty since the mounting bracket, some of the idl...

I do not know where or how one would contact Sanden to see if a comp I had was genuine. Perhaps you could share that info. I had called Sanden's main US office at 972-442-8400 when I was first researching the 4993 to talk to engineering with some questions. That led me on a wild goose chase for a b...

But according to one of the links you posted, the Sanden has a drain plug on the bottom, which in conjunction with the HP and LP ports, should allow for complete draining of the SP-10 oil that's in it now. I don't see a drain plug on the compressor bottom, or anywhere on Sanden's spec drawing. Ther...

Of course they do famously in the residential application. Is there a non-scroll drop in available? Yes, both the TR-70 and the 4993 a...

Thanks tbirdtbird. That does relax me quite a bit, and I follow your explanation easily. Sanden's statement re. the factory oil amount implies what you are saying. I could see that way too much oil could slug the compressor. Conversely, only the compressor needs the oil and some minimum level wouldn...

Background: I’ve spent several months building my knowledge base and researching what others have done to convert the 4th gen Civic to use the Sanden 4993 compressor (also used in the 5th and 6th gen Civics). I won’t go over most of it as it can be found at two main links (for those interested), an...
