I bought a converted rebuilt R134 compressor, new dryer, new evaporator, and condenser. Only reusing the lines. What should I clean the lines out with? Brakekleen or similar?Are you doing a flush and convert to 134 ? Do not use PAG 46 oil in a R12 system
Thanks. Glad I asked!DO NOT USE BRAKEKLEEN!!!!!!!
What you want is from AC Pro, called clean and flush, Here is a link to it from Oreillys. https://www.oreillyauto.com/detail/...ics-32-ounce-a-c-system-cleaner/cqs11/4384841
Also, the rubber supposedly on R-12 should be replaced as molecule size difference between R-12 and 134a, 134a being smaller, means that it will seep through hoses used on R-12. So, if you don't replace and start losing refrigerant overtime, that could be one of the reasons. Don't for get to use green O-rings as well.
Also make sure the filter screen on the inlet side of the compressor is clean!!!
I assume you mean the 1” diameter cylinder I pulled out of the old one. I stuck it in the new one. Should I replace it? Clearly I know nothing about this. Just trying to get it assembled for a shop to charge it. Open to any thoughts.Did you change your txv valve or just going to run the r12 one.
I see it. I was going to reuse it but is there a different one for R134? I replaced all parts cause they haven’t been used in 20 years and comp was frozen up.Txv valve should be gold in color and it's near the evap. Question why are you changing over did you loose the compressor
Thanks. I also pulled a cylinder about 1” in diameter from inside the old compressor. What is that called and should I replace it too?Sonny think of it as the carb on a engine
I dont. It was in one of the two holes that connect to the hoses and had a Spring on top of it. Pulled it out as it had o rings around it.Got a pic
It’s a reman. There wasn’t one in the new compressor. Just in the old R12.Is compressor a rebuild or reman. I believe that comes out. But need to ddl check me on that did it come out from one of the port holes
