Just a reminder dont forget to make shure the RV2 compressor has the oil sump filled to proper levels before you charge it.
The service manual shows how to make a dipstick to check compressor oil levels.Unlike modern rotary compressors which get their oil from the ac charge.

    Dave,

  If the compressor locked up and failed, it most likely contaminated the
  system. I would purge the entire system with mineral spirits before
  attempting to evacuate and charge as you will probably have problems with
  dirt in the system. The dirt will damage your new compressor and cost you
  that plus the R12 you put in it. A complete purge is the only way you can
  clean the system and have an accurate way to put the correct amount of oil
  back in the system. Disconnect the lines at the expansion valve, the
  compressor, and the receiver dryer. Fill with mineral spirits and blow
  through each component until clear. Install new parts, pour in the
  specified amount of oil on the high side, and evacuate. Charge to specified
  amount. Don't take shortcuts, you will be sorry. Been there, done that!

  Note: do NOT use mineral spirits with R134a, they are not compatible

  had a fellow tell me I should put a little a/c system oil in my new reciever
  drier before installing it.

  I'm hanging a new rebuilt A/C compressor on the F and EPR valve also. Gonna
  use R-12

  System has been down for 5 years or so and still had a charge in it. The old
  compressor had locked up and burnt the clutch and bearing up.

  Any comments??
