Onboard air compressors lets see them

[RedTailHawk]

I just saw this installation on a Raptor in the latest issue of Recoil magazine.

Has anybody else tried installing in this location?

You'll see the folks that install Train Horns usually have the air compressor mounted on the frame.

Nice setup, but I'd be worried that a punk would kick the exposed connection and snap it off.

On the last picture, where does the black hose on the left side go?

Disclaimer: I don't have an air compressor, so I'm not familiar with all the parts... I'm not even sure what I'd use it for, but for some reason I feel compelled to have one.

I keep a black cap on it when not in use for both protection and stealth. As you can see, when it's on, you dont even notice it.



The black hose goes down the frame through the bumper for the quick release.

Yes. And it sucked.







If you actually plan to off road your rig, find another location for your compressor.

^ What problems did you encounter Big J due to offroading and the frame mount?

That's my question as well. I like the stealth of it but rocks/mud/debris could punch holes in stuffs and what not. Have you had problems with the filter clogging up on the pump itself?

Looks like you solved the first problem Blue; that little sponge filter in the plastic housing didn't last me one trip. I'm pretty sure a pebble took it out, as there was still plastic bits threaded in the compressor's housing. Running a tube like you did (and I did later) to remote locate that filter (or into the truck's air box like mine) solves that issue.

The second problem I had was I actually ended up seizing my compressor after a few usages. I can't say for 100% sure, but I think it was because of how it was mounted sideways. When I tore the compressor apart, I found the piston had rusted to the cylinder wall, and there was a rusty water line in there, parallel to the stroke of the piston. Because it was mounted 90degrees off from upright, water had been allowed to collect in the cylinder and the resulting rust was enough to seize the piston. I should have snapped some pics, but I didn't think of it at the time.

Mounting it upright prevents any water from pooling in the cylinder. It would have to sit on the piston instead, and I don't think the piston seals that well to the wall, so in reality it weeps down and out of the chamber into the crankcase where it apparently eventually evaporates harmlessly away.

I also noticed that dirt and mud tended to collect on top of the thing, for whatever reason. Not the best idea when it comes to heat dissipation. These little compressors need all the airflow they can get, and not an insulating blanket of grime instead.

Your milage will most certainly vary. But for me and my money, upright and up out of the way of mud/dirt/water/sandblasting/rock pelting is the best way to go.

Gotcha, makes sense.

When my set-up was installed, they actually routed that filter inside the cab under the rear seat, so it would never get clogged.

TRR13 will be a good test to see how mine handles the ruff stuff!
