Thread: EAS Overhaul and GOE Emergency Air Installation

My Bushranger raised the D4 supplying air via the car's compressor inlet but the car's compressor may have been boosting the pressure a little. The suspension system was working so incrementally raised the rear then the front until up to normal height.

It’s obvious but the small piston compressor of the vehicle doesn’t need to move much air and is designed for pressure not volume, which is the opposite of tyre compressors. The outcome above doesn’t surprise me. I’d be interested if the double piston Supacheap would improve the result? Again it’s a large piston volume unit but using two pistons might achieve a little more (assuming it wasn’t the double in the first place).

Was not a test. Just a start of the CY Tele track & mates D4 sits down. Got the rear up plus enough height in the front to get out and back to camp. So the emergency air up is useful just be aware the front needs far more pressure than the rear. Long story - but ended up pulling out compressor & finding the head temperature sensor was malfunctioning. Constantly reading ~170c preventing the compressor from firing up. Ended up cutting the sensor off. Compressor works now but complains about compressor not heating up as its running but situation now manageable.

So today I lowered to bump stops in the middle of a bog hole and had to be dragged out on my belly

I got a Christmas tree of faults (abs, traction control, ebd?, height sensors, suspension control module, etc) as read by iid tool. After clearing them, I heard a gurgling sound from the left near the suspension compressor and the suspension faults remained... I’ll pull the compressor out tomorrow and see if it’s recoverable or replace. I realised just then how low that air inlet for the compressor is.. I had water up to the wheels. But under the recommended limit. It seems possible that water got sucked into the compressor and prob the tank. Joy.

Anyway, this prompted me to think about using my arb ckma12 compressor to manually inflate the air bags should this situation recur.

But it seems GOE is no longer around. Has anyone got any alternatives to their EAS air up kits? Or know how they might be replicated?

I’ve read about pulling fuse 26 to prevent deflation and this then disables the valve blocks. Can the bags be inflated while the fuse is out? How do we prevent over inflation?

Any advice would be appreciated.

The intake for the air compressor is up inside the cabin behind the drivers rear taillight assembly so unless water got in there I doubt water has got in there - you would have water in the cargo area in the rear.

More likely water in electrical connections so unclip and clean out.

On the subject of the EAS recovery kit there is a very recent thread on this very topic and required parts - so do a search for it - in the last week.

What Garry said, but note that the EAS air inlet and EAS exhausted air outlet pipes pass through a plastic muffler assembly sited just behind the compressor and sort of tucked up against the floor. It's possible that this or a line or the desiccant canister has split or been punctured.

Intake is behind passenger side rear light I’m sure

There was a number of electrical clips GOE Gordon recommended extra waterproofing for the suspension electrics for deep water in his book including the big connection block up near the rear suspension strut.

My view is that Denso tape would be ideal but he had a suggested list of waterproofing sprays.
