My New CS4i From GX Pump is making a metallic clicking or tapping noise under load. Sounds almost like a galloping horse. Any one else notice this noise? Is it normal?
Help GX CS4i Metallic Clicking Noise Under Load

Mine makes a noise. Kind of hard to say if it's anything close to what you're hearing, but mine almost sounds like a valve or diaphram closing....if I use my imagination.
The thing is, w this compressor opearting as quiet as it does, I can actually hear it function. So it's pretty easy to "hear things" and get concerned about sounds that would otherwise be drowned out by the normal operating noise of any other brand (looking at you, Yong Heng)

Is this the first time using it out of the box?
Edit: I did a fast search and found this poster on another forum post this as he was concerned as well...
"It isn't that noisy, but it whizzes like a star wars fazer slowed down. It also has a rhythmic thud, and a metalic clanking sound.
I was expecting it to purr like a kitten. It really doesn't sound very refined to me."
Does the quote above sound about right?

They seem to do this once running for a while and at a higher bar. There is some slop on the connecting rod end. I was told this is normal. If this was spinning @ 1800 rpm or higher, that would be a different thing.

My unit is the JTS model that is equal to the GX CS3.......Mine sounds like a galloping horse and Cinderella clicking her heals over and over.

It's the side clearance and not the bearing, at least on mine. I got curious and checked it out.
My CS4 makes a lot of interesting noises including the rhythmic "thump" mentioned above. I time this thump every time the compressor runs. So far, it's held steady at 100 thumps per minute. The instructions, such as they are, advise to be alert for any slowing of the compressor. Timing the thumps appears to serve the purpose.

Crank end. I thought about some thrust washers, but left it as it. Has about 1/8" of side clearance.
That it! You hit the nail right on the head.My unit is the JTS model that is equal to the GX CS3.......Mine sounds like a galloping horse and Cinderella clicking her heals over and over.

Thanks everyone for the reply. I went back to the AEAC review of the JTS Comp 100 / GX CS4I. One scene is a bottle fill and Steve lets it run with no narration. You can hear the metallic noise under load. I picked it up on one or two other YouTube videos as well. Most reviewers either cut out the fill audio or narrate over it. It's nice Steve picked up on the noise and let us hear what we would be getting. Mine doesn't prevent conversation but the clickity clack although rhythmic is irritating as heck.

Agree is annoying as hell. If your just topping off a gun, this should not be an issue.
Sound like these have sloppy internals. It has a one year warranty so I guess it'll break in or just beak....
