AC Question
I have changed out my old hoses and plan to charge it R-12 once I pull a vaccum on it and conferm that there are no leaks in the system.My question is how do you get the oil into the system and how much? Neither can of R-12 has any oil in them.The only way I can think of is to fill one of the manifold hoses prior to introducing the freon to the system.Or do you disconnect a hoses ,add the oil then pull the vaccum?Then add the freon? :confused:

Re: AC Question (rdrman)
the easy way is to get a can of R12 with oil, but just changing hoses should not make any additional oil requirement...in and of itself...I suspect you may have lost a lot of oil from rapid discharge or long term compressor seal leakage....
at any rate, I"d change over to R134 and quit fighting the battle as they will not sell R12 oil in a charge can...but if you open the lines and add R1`2 oil by pouring it in the hi side...that's fine too....just watch the amount, don't want to flood the system...
I did things the easy way....I made my own adaptors to go from R12 gauge set to R134 cans, and had done with it....made things simpler that way....the gauges are more or less the same on the pressure/temp thing...close enough anyway...
that way SO FAR we/I can buy R134 and R134 with oil charge, and do my own...

Re: AC Question (rdrman)
You can dump it in the hose, directly into the compressor, or use a can of R-12 "oil charge". If you dump it in as a liquid, turn the compressor over by hand 10-20 turns after it is all hooked up again to prevent it from trying to compress the oil and damaging it. If you are going with R-12, at least use a oil that is compatible with both R-12 or R-134A in case you want to change over later. This assumes you replaced the compressor and/or receiver-dryer and lost a bunch of oil. Heres to cold air! :cheers:
