I am redoing the complete system on the 79' 240D again.
Last time I hope.
Does anyone know of a way to get the lower front bolt out of the compressor so I can remove it from the car? It is the York style compressor. I have worked on it for days and I just can't get a wrench in there to turn it. The bolt is broke loose but I can not turn it because the wrench is hitting somethig from every angle.
Do I need a special tool?

My goal is to remove the compressor and drain out all the oil and Start fresh with new oil and a flushed out system.

Can someone tell me what amount of oil goes into a completely empty compressor as an initial oil charge?

What weight should be used or range of weights?
I have seen mineral oil that is 500 sus. Alkabenzene oil that is 150 through 500 weight.

Any thougts on weights for this would be awesome. I'm really looking for what came in it from the factory and then make a decision based on that.

I know you all are tired of talking about a/c systems bu I really need some help on this.
And I searched and found some useful interesting stuff but nothing specific.
