I have a new Harrison A/C compressor from Rusty ready to go in an '83 240D. A tag says oil must be added but does not say how much or in which port it should be poured. You have an R4 as you already know. The way the ports are oriented (upside down from GM), you can only put in about 2 ounces before it will run out when you tip the compressor up to install it. So pour a couple ounces in it and at least 2 more ounces into the dryer fitting. the whole system when new would call for about 8 ounces of oil and it is very likely that most of your has been lost due to leakage. With the oil in the compressor, you need to rotate the piston assy and lube the seal. the clutch should face down and what I do is clamp a 14mm deep socket in the vice, set the compressor drive shaft nut on the socket and rotate the compressor a couple turns. It will turn fairly hard but should turn smoothly. by the way, does your compressor have the X embossed into the front bearing cover to denote that the oil feed port is up when installed. How about your old one? If you got it from Rusty, it should be set up for MB engines, which basically mount the R4 upside down from GM applications. There was quite a discussion about whether is important to have the oil feed up but if you have the compressor in hand, I would at least check it's orientation. You can unbolt and rotate the front bearing cover to achieve the correct orientation. Lift the front cover just enough to insure that the O-ring gasket is not sticking to the cover. I will send 3 pictures, separately, which you will have to extract from Kaleb's files.
