Thread: Spot to mount Air Compressor?

Or not bother with a compressor - use the one you have already.



You need a regulator as the tank air is at 210PSI +.

First issue. The spare doesn't fit (in usual spot) when properly inflated.
So now i really should have a compressor on board all the time instead of just chucking it in when going on a trip.

Has anyone found a nice place to fit one in?

Same spot as a few others. In front of the main Battery. Made a bracket to mount the ARB compressor from some bits from Bunnings. Used existing mounting points to bolt it all into place. Solid mount and great compressor.

nnn

If at first you don't succeed....hopefully this (reduced size) attachment will get in!

The bracket uses two existing captive nuts just in front of the battery box. The lower bolts necessitated removal of the inner guard to drill the holes and fit them - drilling blind would be risky due to the hidden construction, ribs and components beneath.

Orientation and location of bracket/compressor is intended to minimise risk of the compressor being hit with a jet of muddy water through the holes below. Still leave the plastic plug in place when not in use to keep dust etc out of the coupling.

The compressor works very well (even better with engine running).

More (and higher resolution) photos in my gallery, if of interest.

For those who are interested tapping into the tank is easy.
You will need to get some bits for the connections. Bunnings stock some but you will need a stop cock as well.
Get an engineering shop to tap a hole in the tank bung.
You will need to release the air from the tank but slightly loosening the bung.


DO NOT UNDO FAR, JUST ENOUGH TO RELEASE THE AIR SLOWLY. THE TANK HAS AIR AT 210psi PLUS!

For this reason you will need an in line regulator to bring the pressure below 100psi.

I used a different one (and removed the guage) but this one should be enough for tyres:

Order:
Tank
Stop cock
regulator
Nitto self closing connection
Male/ female ended nitto fitted hose
tyre guage and fitting.

As the suspension is down with the bung out you will need to take the bung to an engineering shop to thread it for you.
Put it all together with some Teflon tape and check for leaks.

You will need to close the valve when connecting and disconnecting the hose.

Usual caveats apply do any changes at your own risk.

HI Caver,

I'm very interested in your system, could you please answer the following: -

Does the stop cock thread/tap into the existing brass bung?
Why do you need to close the valve to connect the hose? ie isn't the pressure regulated at connection?
Is the grey line the factory air suspension hose?

Thx for sharing this mod with us all. Cheers

All threads you will use are 3/8 inch fittings I think, so a hole needs to be drilled and threaded in the bung to match the thread on the stop cock first. You may need a male to male connector for this or between the stop cock and the regulator.

Even at 100psi there is still a lot of pressure making it hard to connect the hose especially as you are doing it underneath the vehicle.

Will. Did you mean the air intake or outlet that you plumbed to the rear.
