I have a small air compressor (actually 2 identical) Has been working great. Had it tucked away behind my Jig Borer but needed it outside before a friend gave me another Identical one. (it runs OK) Before putting it back behind the machine I wanted to extend the drain and add a valve so it was easier to drain any water that accumulated. Removed the plug, maybe a cup of water drained and I let it sit having another compressor until moisture had a chance to dry. In addition I removed the oil drain plug and drained the oil. (didn't seem very dirty) Replaced the oil with 30 non detergent oil. Didn't get a chance to hide it behind the Jig Borer yet but needed some air. It's a small compressor on wheels, handle removed to fit the space behind the jig borer with possibly a 15 gallon tank. Motor about 1/3HP (didn't check) Capacitor start (single Cap.) 120VAC single phase. Started well ran quite other than the typical puttering of the valve. I know it shut down one or 2 times and restarted. while I was near the compressor it attempted to start again but failed, it attempted, rotated compressor pulley about 1/4 turn and stopped. I quickly unplugged it. Compressor pulley about 10" motor pulley 2", semi new belt in that it was changed a while ago and in excellent condition nor is the belt banjo string tight plus it was running as adjusted for a while when belt was replaced. Wanting to check it out a day or 2 later I plugged it back in, started as it always does so I continued a lathe project so as to be near the compressor when it shut down. When it did stop I lowered air pressure with air nozzle until it attempted to restart, it didn't and made the same approx 1/4 turn of compressor pulley. I unplugged it, when attempting to rotate the compressor by hand it turned easy until on compression stroke then turned hard. I made no changes to the pressure switch and it is mounted directly to the tank, compressor outlet is also connected directly to the tank, no means of unloading provided. Power plug was in wall mounted outlet with no other load connected, I assume voltage is 120VAC at the outlet though I didn't check but no reason why it should be low.
Any ideas as to the problem? Capacitor getting weak? Approx 8' power cord getting old?? Looks good, no cracks in the rubber coating. Outlet valve leaking putting pressure on piston?
