Kobalt Air Compressor #0300841 is making loud mechanical noises when I turn on the compressor. Like metal to metal.

Well, that's an oil-free pump, so it isn't low on oil.

If you're lucky, it's the o-ring on the piston, but you'll need to measure it to find a replacement - the pump/motor only comes as an assembly (stupid).

If you're not so lucky, you may find the rod or counterweight broken. And you probably won't be able to find either one as a separate part.

Sorry, but good luck.
