On a side note, no oil would drain from the old compressor, as in not a single drop even turning the pulley. However, I drained about 8 oz out of the old receiver/dryer. Total system spec including compressor is 11oz. Eight ounces of oil came out of the old R/D and none from the compressor? Oh, my There was dye in the system. I suspect they had work done to it at some point. Other than the missing orifice tube, I do not see anything that was obviously replaced. The evap up front has the locating dimples for the orifice tube. The OT was missing yet the system still worked to some degree. A ..read more

I think it is time for a new gauge set. The gauges still work great, but the hoses are giving me more problems. About 10 years old, and a cheap set to begin with, probably just time to start over. I use it 2-3 times per year. Only filling a system average of once a year. My vehicles are slowly getting newer, sort of. My trucks are still 12-19 years old, my wife's vehicles range from 4-11 years old. I no longer have old junk at least. Now everything is in very good shape (except maybe her ram, but that is another story). So I'm not needing to do as much a/c work. Long story short, do you have ..read more

I don't know of any tools for the purpose of which you speak. But an alternative is to obtain whatever size aluminum tubing you need, purchase an already formed o-ring fitting in the same size and matereial, swage each end of the tubing and fitting (so that one fits inside the other), and aluminum-braze the two together. Swaging tools can be had for reasonable prices. The cheapest way to do it, or braze connections. aluminum-flux-core-wire Statistics: Posted by Tim — Sat Jul 27, 2024 12:34 am ..read more

Project: Custom AC installation in a 1993 Mazda RX-7 with non-standard components and non-standard heat exchanger orientation aka "V-Mount" radiator and intercooler. I've machined custom mounts for a variation of the NipponDenso SCSA06C compressor. I had a slow leak in my original one/previous iteration of this configuration and suspected the original compressor was leaking/needed a rebuild, so I figured might as well move to something designed for R-134a. Hopefully, this compressor isn't going to be a step backward, as it is much smaller than what was in there and I should have picked someth ..read more

And here is what MACS says: —609 Certification is part of the U.S. Clean Air Act of 1990. Since 1992, federal law has required technicians working for pay to be certified to recover and recycle refrigerant. In addition, only certified technicians are allowed to purchase R-12. As of January 1, 2018, purchasing two pounds or more of refrigerants is also now restricted to certified technicians. Before purchasing refrigerant, you must display a Section 609 card. —The five mobile A/C refrigerants covered under Section 609 are R-12, R-134a, R-152a, R-744 (CO2), & R-1234yf.

Agree. The -1BAR and 30In HG scale are no substitute for a proper vac gauge, as you know. The fact that those scales are on the gauge gives the owner a false sense of accuracy Statistics: Posted by tbirdtbird — Fri Jul 26, 2024 7:37 pm ..read more
