Thanks for making these videos. I have learned a ton about working on old compressors from them. I think the hardest thing is to find the right parts for a decent price.
How do you clean the head and valves when they all full of carbon build up? is it a good idea to soak everything in gasoline to loosen gunk down then scrub everything?
I have a Quincy 325 and it use to leak air from the air filter and dip stick tube so i took the four tops off and two of them was rusty and dirty and internal parts was stuck so i cleaned them up and put it all back together and now it doesnt leak from the air filter and dipstick but it leaks from the two small holes on the aide of the unloader. What causes this?
My best quick guess is the diaphragms are leaking. I assume this is when it is shut down. Quincy seldom put a tank check valve on the 325s but that is always a plus if you would want to add 1 now. you may have not needed to clean the valve ( but it was good you did). you may contact me through thecompressorguru.com. thanks Bud
if it leaks it can be as simple as apiece of dirt . you can also have a bad valve disc sometimes a VERY VERY weak spring. if it leaks you have to do some looking.
you will be hard pressed to find a service manual. you can get parts books . most parts books will have the torque specs in the description of the part. hope that is all you need. Feel free to contact me through thecompressorguru.com.
Buenas para udt maestro excelente video tengo un quincy modelo 320 y estoy buscando un manual del mismo , sabe udt donde lo pueda encontrar sin problema alguno ya que he buscado en Internet y no logro encontrarlo, excelente truco el de revisión de sellado de las válvulas con las gasolina para saber si existe fuga saludos y gracias de antemano
Buenas tardes gracias por tu mensaje. Recientemente he buscado por partes del modelo 320 sin ninguna suerte pues esta descontinuado. Si encuentro algun manual estaré confirmandole con un reply "Consegui" y apartir de ahi le solicitare un email para enviárselo . Las gracias a Carolina que me ayudo a traducir este mensaje.
Hello to you and Carolina again, thank you very much for responding and attending to my message. The issue is that I acquired this quincy 320 that had been working for a few decades in a factory and which since then has not been systematically and correctly maintained. At the initial moment of obtaining it, the first thing I do is disassemble it completely and the valve system was clogged, with a lot of rust and charred and that's when I see your work on yotube. I managed to clean them completely but unfortunately a valve does not seal on the part of the rings. At this moment I am restoring it as new and with a solution for that valve that does not seal due to the deterioration of the rust that decomposed part of its seat. If it is of your interest to know how I repair the valve so as not to discard it since I do not have the possibility of acquiring a set of them. I support your channel and thanks to you I have managed to understand the operation of the compressor, please excuse the length of my message and that I had to assist the google translator. Best regards.
@@sergioandreshelguera4024 the google translator seems to work well. so I just got off the phone with Quincy I now have a pdf of a 320. good news is valve parts are available. next problems are we are going to have to ship to you. where are you. I may not be able to ship to your country. I think the best way to do this would be for you to contact me through thecompressorguru.com and then we can start emailing each other. looking forward to hearing from you Bud
I’m rebuilding the valves on my Quincy 230-36 compressor. The previous owner supplied a rebuild kit with the unit when I bought it. The parts seem correct --- new style springs, new washers, new copper valve seats, and the correct gaskets. I’m curious about one thing regarding the high pressure discharge. They were pretty rusted up, but not seized or beyond anything a good dip in Evaporust can't fix. The valve seat seems to be in good shape. When I reinstall everything the valve seat “disc” that the 5/8” through-bolt threads into does not cinch tight against the four main-assembly-feet --- rather it spins freely. I’ve checked to make sure the valve isn’t leaking by filling the bottom (upside down) with fluid to see if it leaks out. The spring and washer are holding as no fluid leaks out. My question is, is it normal for the unit to spin freely, or should the valve seat “disc” set firmly against the four feet of the valve assembly? There's a moment around minute 12:40 of your video as you remove it from the pot during your fluid test where I think I can hear the assembled parts clinking a bit --- which is exactly how mine sound. But I want to make sure before completing my rebuild. I think we all hate the agony of tearing into a fresh rebuild to "fix" a problem that could have been addressed much easier if it were earlier on. Great video! Thanks for your help.
Robot it is normal for the shouldered bolt to bottom out before the valve bumper is tight ( just what you described) make sure the valve disc doesnt get caught between the bumper and the feet of the valve cage or housing ( I do not know what that is called I should look it up in the parts book) anyway when you install and tighten the valve down those feet will go tight against the valve bumper . Good Luck, if you want to call me feel free to contact me through the website thecompressorguru.com
when you were setting the flat washer/disc into the suction/intake valve assembly, you said let me know if you know a trick for them, I happened to see a trick in this video at this timestamp: th-cam.com/video/hAA86q7QkJQ/w-d-xo.html (he uses a small screwdriver to depress the spring so that the disc sits flat down into the valve)

feel free to give me a call, I have many aftermarket parts that the pricing is great. contact me through thecompressorguru.com
you mentioned HIGH cost parts, check out the next episode coming on August 2 for a great example of OEM vs Aftermarket.

@@mexinumba1 Kerosene or diesel is best. It doesn't evaporate as fast. I also used brake cleaner and a wire brush to get the last bits off.

If you do the fuel test on it and the fuel leaks? does replacing the seat and spring fix the problem?
if it leaks it can be as simple as apiece of dirt . you can also have a bad valve disc sometimes a VERY VERY weak spring. if it leaks you have to do some looking.
Hi, where can I find service data for these old Quincy's? Is contacting Quincy the best option? Or is there a place I can find repair manuals online?
you will be hard pressed to find a service manual. you can get parts books . most parts books will have the torque specs in the description of the part. hope that is all you need. Feel free to contact me through thecompressorguru.com.
