Also remove the drain plug to let water out of the tank. I had the original belt on my compressor over 30 years. No need to check it - you know if its broken or slipping. Still works like new, they don't make stuff that last this long now.
My friend thank you for the nice video. My compressor sometimes if the pressure dropped it is not restarted automatically. You have any solution for that ?
Thanks. I've also heard you're supposed to let all the air out after each use to keep the moisture from the air from rusting the insides. I've also heard you can get some kind of a dryer to pull the moisture out if you're going to store it for a while. Anyone know about this?
Thanks! This is a nice video and very helpful.. I got a question for my vespa centrifugal air compressor. I want to change oil for the first time but there are two oil cap with different colors (white and red). Which cap should I put my new oil? If you like i can send you a picture.
I have one of this same type but for a while it gets very hot and shut off and it doesn't comes on until it is cooled down again,what do you suggest is the problem?
Although helpful in understanding the minimum service requirements for an air compressor, there was no mention of electrical isolation - the unit appeared to still be plugged in to the mains supply. No mention of venting all pressure from the unit (the unit was run up to warm the oil before draining) Additionally the guard was removed to access the drive belt - with the power still connected? Before any of the above maintenance is attempted, complete isolation of all energy sources is a must :-)
i have a craftsman 5 gallon, 1hp,125psi, model 921.166360. my air compressor gauge only gets up to 25psi and it won't goes any higher.. do you happen to know the problem. thanks
Most or all of the compressors that I have seen use a 30 Weight Non Detergent Oil in them. I think Amsoil is a 5-30 Detergent Oil. I would stick to the real oil and stay away from the synthetic oil. But that is just my opinion.
my air compressor motor spins up then slows down, it is also having trouble pressuring the tank. I replaced the pressure switch because it had gone bad but this is now happening. Could this be a bad check valve; the pressure switch I got is bad or could the motor be bad. It is a oilless air compressor motor.
Hello Sir very nice and helpful video. I need your suggestion. I'm a dentist and I have small (35Litre) capacity air compressor at my clinic. I'm facing iasue that with air water is also coming. And one day i forgot to switch off the button but I drained valve on so the compressor was running whole night. Now it gives very bad smell and water also comes out from it.. i asked here this to some releted person but they are not so aware about this.. So what should I do now..? Pls reply soon..
Hi Ravi, unfortunately at this time we are unable to offer technical support. I would suggest contacting the manufacture for further information. I sincerely apologize.
Can you do a video on this compressor about the check valve? My compressor needs a check valve (when the tank fills up, the unit begins to seize and when I turn it off and then back on again, the pressure switch no longer works until I empty the tank) but there aren't two inputs into any of the check valves, just one, and I can't figure out if my unit requires two separate check valves or? My compressor, by the way, is a Craftsman 919.156520
Thanks for your reply. My compressor check valve is different than many of the others' I've seen and I initially couldn't get mine out to confirm its identify as the check valve. Ultimately I was able to remove it. And it indeed needs to replaces, along with a few other parts. Do you carry a regulator rebuild kit that would work with my Craftsman 919.156520? Preferably with a new knob too?
Hello, it looks like Craftsman has discontinued the regulator for the 919.156520 Compressor. I cannot locate it or a rebuild kit for it. You may want to try a local compressor repair shop in your area.
My compressor is almost identical to that porter cable, though mine is a older devilbiss. On that porter cable and mine, there appears to be a "drain plug" on the top/front of the compressor housing. Just to the right of the air line coming out of the top of the compressor. What is this plug for and should I mess with it at all, ever? Thanks in advance for any advice you can give.
eReplacementParts.com Negative. It is at the top of the compressor right next to the air line that comes out and goes down to the tank. It looks like a drain plug.
my compressor compresses air only when i block the suction side of the 2nd cylinder, if i wont do that, it will not produce any compressed air.. any suggestion what happen to my compressor? "1 hp, single stage 2 cylinder compressor"
+Jv Datz My first guess it to have you look at the Valve Plates under the cylinder heads. Typically if the "Fingers " on the valve plate becomebroken or warped from heat, they won't seal correctly. While you have the head off it's wise to check the piston and ring for wear as well. I'm a little puzzled how the compressor is pumping air while the inlet is plugged. Is It pumping air from a leak in one of the gaskets or a crack someplace?
The recommended oil for most compressors is 30W Non Detergent. It is important the oil be Non-Detergent for compressor pumps. Also, some smaller compressors are listed as OF or oil free. Do not use oil on these as it will ruin the pump.
I GOT AMSOIL 30/40 SYNTHETIC NON DETERGENT ON THE AMSOIL WEB SITE,,,COMPRESSOR RUNS COOL AND YOU ONLY CHANGE IT BOUT EVERY 8000 HRS ,,YES 8000 NOT 800,,,,,ITS ROUND 12 BUX A QUART BUT IF YOU WANT TO SAVE YOUR COMPRESSOR ITS VERY CHEAP,,ITS THE BEST OIL IVE SEEN ,,,,,,,
