A/C People! Need your help. I just got a new compressor and clutch. Installed it in the car, but can not hook up the lines to the compressor. Because the old compressor has different ends (Screw on type). The new one has Tubes sticking out of it so the hose has to be clamped down with a hose clamp. And the base where the lines go in is different then then the old one, so I can not use fittings off the old one. (Poop on a stick) No big deal, I will just replace the hoses. But what kind of hose do I get built? What kind of pressure does the A/C compressor put out? Second question. Since the compressor was not fully locked up, just starting to lock up. Do I have to replace the Drier? Or should I replace the drier anyway? It is almost 40 yrs old.
If the compressor was failing due to internal issues (Sounds like it) I would replace the drier/condensor and flush out the evaporator, before charging it up and useing it.
Yes it was an internal issue. I will do what you say Mavman72. Thank you. Have to spend some more money then. Maybe next month I will have it ready. What about the hoses? Anyone?
AC systems are very high pressure. The hoses should probably be made by an AC shop. They will need both ends and preferably the old hoses so they know the configuration and length.. Be good if you could drive it in.. Most of us don't have the necessary crimping tools for making the hoses in the garage. OR maybe change the plate with the fittings.. No pic so hard to imagine what you have.
Some systems can get as high as 400psi. Any weak areas will give for sure.. Not that it should run at 400 just that it can happen.. Hose clamps will have failed long before lol..
as Gene said...we need pics. and what compressor are you trying to install that need hoses made onto it?
Ad said: Get all new hoses. I would at least get the dryer rebuilt. You might be able to get away with just flushing out the condensor. There are places you can send the dryer to and they will rebuild it. If I had to do it all over again, I would have got a brand new style of condensor. Some seem to think a newer style condensor works better with the newer style of compressor and the R-134a. Mine works O.K....but I now wonder if it would have worked better with the new style of condensor.
I will take pics tonight of the new compressor ends. I also just bought a new Drier and Condenser last night. So when it gets here we will put it on.
What's the new style condenser look like? What's the difference? I will need a new one for my car eventually so I'd like to know. Is the old style even available?
I have a universal condensor frm Classic Air, Florida it fit (installed)vry easy. I think they can/will rebuild org. type units. I don't know if it's worth the cost unless ur after factory appearance. My condensor is cross flow. I have pix of it somewhere - Maybe in my gallery.
At 130* R12 will be at 180 psi. R134a will be at 200 psi. Give you some idea of the pressure the hoses will be seeing. I would take them to an auto ac shop. Make shure to mark the direction of each fitting in relation to the hose. They don't like to twist.
I am sure an expert will chime in, but I am pretty sure those hose fittings will unscrew form the compressor and then you can get the correct fittings.
The head of the compressor should be threaded to accept the factory cutoff valves/fittings. The idea was that you could screw in the block off valves to isolate the compressor for removal. Do you happen to have your old compressor? Those valves will unscrew from the head and you might be able to transfer them. There might be a difference between the Tecumseh and York compressors, but I thought the valves were all similar on the Mavericks, Mustangs, etc. The hose has to be a barrier type hose for use with R134a and you will need a larger, more efficient condenser. The original condenser is a serpentine type condenser and is too restrictive for the heat load you get with R134a. The newer parallel flow condensers work well and universal fit types can be found at any good AC/radiator repair shop. They usually can make the lines you need as well. An electric condenser fan will help as well but it's a tight fit on the front of the condenser.
