Re: Best Compressor For R12 In Diesel Pusher

Why would you "start from scratch" with R12?

Properly sized components work great with 134a. The cost of the components for a system is really no different for either refrigerant. The cost of R12 vs 134a is significant however.

Re: 1960 Caddy Hot Gas Bypass valve rebuild

Many of them had straight fittings like this one:

But I think they went to the brazed pipes to get away from the 135 degree hose fitting. Pipes are more robust and cheaper.

Re: 1960 Caddy Hot Gas Bypass valve rebuild

Those are brazed in to the body. Don't try to remove them.

Check the cam surface, and pintle for wear. Check the cam pivot too. Lubricate the pivot with a tiny bit of good oil, and the cam surface with a thin film of wheel bearing grease.

Re: Someone to Weld on Fittings

Much better to replace the fittings.

Re: 59 Deville AC problems

Again.

What type of oil, how much, and where was it installed?

How much 134a was charged in to the system?

Re: 59 Deville AC problems

The A5 with the Hot gas bypass worked well. The valve is an easy rebuild, sometimes the cam & pintle are worn. An A6 conversion probably works ok, never messed with one. Are you usure of the hose routing? Pics in this thread: https://www.autoacforum.com/viewtopic.php?f=3&t=331 Finally how mu...

Re: How to charge custom system

Well, since most of us don't have a wind tunnel, we find other ways. The physics of a refrigerant gas make it predictable at a given temperature. As long as the system is above 50f there will be both liquid & gas. The P/T relationship will affect the gas pressure, but the liquid volume change ov...

Re: Upgrading (and remounting) a Vintage AC system

The York compressor is probably geared down to suit the application - how big is the crankshaft pulley? Any direct mount compressor could be adapted to that mount - but direct mount compressors tend to have serpentine belts so a clutch change would be needed. A V5 for instance would be a great choic...

Forget the silly to tap junk.

No matter what size the can is, or what is in it. Just side tap it.

Re: 2006 F250 AC Issue

Well, outside of the obvious air leaks on the evaporator box you need to deal with, there are a couple of other issues. 1) The cycling switch hysteresis. This is a problem I have seen with this vintage Ford before. It should not be waiting for 60 psi to turn back on. It may also be responsible for t...
