Now If this was a severely burnt compressor or damaged you possibly would see very tiny metal flakes inside the refrigerant and dark gray or brownish oil
Think most of the guys who watch your stuff regularly, realize you could be spending your time more productively/profitable elsewhere. Yet you take the time to demo details like this anyway on “film”. It really is greatly appreciated.
He’s a little bit of knowledge need to be accessible and available to everybody around the world. The guy in Poland wants to get into the air-conditioning business he has money to invest and he called me up and we had a couple conversations about tools and equipment I’ve had guys from the Philippines called me another guy for Ghana in Africa guy from little island nation the guy from Jamaica contacted me Italy Brazil all these different countries saying they don’t have access to these kinds of videos tools or equipment some places don’t have training schools.
@@coldfinger459sub0 No doubt. I am on the other side of that coin…I have access to all those things, but unable to fully engage as I am already decades into a different trade path. (Frankly I need the income and getting close to retirement numbers). So your videos provide access to the insights of a very experienced tradesman that are quite unique and valuable to people in similar circumstances on both sides of the equation. Thx again…Cheers 👍
While you were talking about vacuums I was wondering something else. I know with an AC compressor when you oil that you're going to get some moisture from the air worked into the compressor as you turn the pulley. So that I can get all the moisture sucked out is it okay to turn the pulley on the compressor while pulling a vacuum?
No you can damage the front shaft seal. The French South seal on some compressors were never designed to spin while they’re under a negative pressure.. The way they are designed an angle is for positive pressure and they’re constantly being forced fat a fresh supply of oil . The vacuum will get everything out of the compressor . Not everything but the majority, because there is a molecular bond the physics of the water molecule bonding to the POE oil or PAG oil a certain percentage. You just cannot remove completely with vacuum. You can reduce it, but you’re gonna not going to get it all out . If you are do it yourself person then it’s really easy for you to leave the vacuum pump on for 24 hours you can never over vacuum. All you can do is remove more moisture, the longer the better. .
I enjoy your vids on a/c work, very helpful. I appreciate the time you take. After watching this video I get the impression that I can use this sight glass to extract unwanted pag oil from my system without the need to open the system. Do you think this would be possible? Many Thanks, Michael
That would be a really long tedious method of trying to do it Especially if the high side was located on the vapor line and not on the liquid line. Depending on the situation it could work but if you have the wrong situation your grandchildren will grow up and get married and have grandchildren themselves before you could remove enough oil. Depending on the situation it’s possible it could work but did you see how a little bit of oil came out
@@coldfinger459sub0 very funny, it so happens the HS port is on the vapor side too. Well, I have about 9oz instead of 6oz pag in a VDC type compressor that sits on the bottom of the engine bay. It was my goof. Cools well, makes a little noise now and again at idle but quiets down when i add rpms. I think I will get the glass just the same since I see how well it helps you and just monitor the refrigerant from time to time. See where it goes from there. Very appreciative of your time. And yes, I will still try it just to see what happens, you never know until you try. Cheers, Michael
@@MichaelA-xx2ls you can always learn from every new thing that you try and you can learn to use it as a tool and learn to use it as a learning device. As long as you make an effort to learn one new thing every day
