Question about Dewalt D55153 1.1 HP Continuous 4 Gallon Electric Hand Carry Compressor
My DeWalt D55153 oil-lubed compressor won't get up to pressure. At first, it would only go up to about 100 psi and then keep running but not increase tank pressure; then it was 70, and now it's getting stuck at about 60. I've adjusted the pressure cut-offs a few times so I could keep using it, but at this point it's not giving out enough pressure. I don't use this compressor often, and it usually rides in the back of the van. Over the years I've changed the oil every year, since I don't get very many hours on it. I've noticed that the oil was dirty when I changed it last year, and this year it looked like it may have been metal in the oil. It's been making a bit of a pinging/knocking noise when it runs. Am I dealing with a pressure switch issue, or is this a motor issue? Is infrequent use and constant transportation a problem for this type of compressor?
Just a guess but I think you have broken the rings inside. If you keep running it with broken rings you will trash the cylinder inside. I think you can buy a new pump for it if you are not mechanically minded.
