A/C Compressor Working - Can I Simply Re-Charge?

[jwintersjr]

I'm new to the forum and about "one year old" in learning the mechanical design, function, repairs, and maintenance of my '85 300D.

I thank everyone for the support I've gained in reviewing SEVERAL old posts over the past year!


My most recent project is getting my a/c functioning. The a/c compressor belt is missing (since purchasing the vehicle.) I can easily spin the pulley, so my understanding is the compressor is NOT locked.

Is it okay for me simply put a belt on and recharge the system? Although I prefer to restore to original R-12 coolant, with this project I will do the R-134a conversion, for convenience and safety. Cold is okay with me. It doesn't have to be frigid.

The R-134a coolant has 6 ozs of lubricant. With this, and an EASILY spinning pulley, I do not have to add any more lubricant to the compressor do I?

Thank you for any help shared!!
