Take a listen to my compressor

[Kaizen]

With my new compressor in the new shop I have to sell this one. But I’ve never really rebuilt one so not sure what these noises are. Want to adequately explain in my ad. It did take 12 min to get up to max 135 psi which puts it at six cfm. Tank says ten cfm at 90psi flow rate. Listen to the clip and you can hear the sound change ten seconds in. Thanks in advance

Sounds almost like one cylinder is dropping out or its got a rod knock. Does it always start the same then have the sound change after the same elapsed time?

It’s only a single cylinder I believe. Totally random. Usually sounds like this. Just replaced the belt as it was slipping. Has sounded like this for years.

It's a twin i believe originally from Campbell Hausfeld, many compressors have that same pump rebranded on their compressor. While it does sound a little off, it doesn't sound terminal. I wouldn't have a problem listing that for sale with the disclaimer it seems to be down on air output. I would leave it powered so an interested party can hear it run.

Thanks will do

Was the tank at zero pressure when you started the video?

To me it sounds like the compressor took 10 seconds to build enough pressure for the pump to actually start compressing the air. Basically, it was an air pump, then it became a compressor.

No that was several minutes in. It does that every once in awhile. Agree it sounds like a cylinder compressing but not making compression. But only does it a few strokes once in awhile.

A little slack in the piston walls. Rings on piston are rotating. That’s why the sound change is random

doesn't sound bad to me, are the pulleys tight on the motor & compressor?

Yes put on a new belt as I had some slipping. Nice and tight. Thanks

Does it have a belt guard on it, I have had one vibrated at times and I thought it had a problem until I put my hand on the guard and the noise quit.
