Hi all, i'm wanting to replace the compressor sooner rather than later because I really don't want to have to deal with a compressor failure on the trail or the likes. The trucks a 2006 SE (fully loaded) with 120k on it. The engine was replaced about 30k ago by previous owner. (Auction buy with blown engine) Everything on the truck is amazing. However the compressor has never been changed. It works very well for its age and does get used several times a week in off road mode. Still... I would love to replace the compressor with the ARB dual compressor unit. These are my reasons why. 1 Reliability this truck will be going to college w/me and i'm trying to bulletproof it as much as possible. 2 Water fording. In the areas where I go we see a lot of water and cross a lot of it. In general I don't like the compressor being underneath and the new one would be located in one of the rear storage bins. 3 capability. The dual unit provides plenty of power for both tires and air suspension. Not to mention the OEM is no speed demon and is far from 100% duty cycle.

Now my questions.

First and foremost is it even possible. In my head it seems simple with the switch wire (on/off) for the compressor going or splicing into the OE relay wire for the compressor turning on and off. provide power to the compressor and plumb it all up. But.... its a rover will some computer crap the bed by noticing a non OEM compressor?

Wiring; the ARB draws more power than the factory. As long as I get power to On/off relay to turn it on and off wired correctly can the OE power lines be left undone without fault lights coming up or will I have to work with the factory wiring and find a similar compressor the draws similar loads to the OE.

What are the specs of the factory compressor. Anyone have figures for the pressure of the EAS components, like in the bags in the tank ect. Also how much is the compressor rated for.

TIA!

 

I don't think I've seen this ARB compressor. Do you have a link?

In general I'd discourage this effort. While it may be possible, the benefits vs. cost/effort don't really pencil out.

Thats the compressor.
I would also like to add I have access to an extensive shop including a fault mate for any codes or programing. (Its good to have car friends)

Would you mind just for conversation sake what the issues you see with swapping it? I came from d2/p38 land where this was quite common.

 

I don't think t will work as the exhaust valve is integrated into the OE compressor. I do not believe the ARB has a provision for that. The OE is not a simple on/off unit.

 

The unit you linked to doesn't look like a suspension compressor. Further, there's tons of logic driving the cycling of the compressor in the LR3. AFAIK, there's only 3 that work. AMK, Hitachi, and a POS Arnott model. I just don't see it working for these reasons and what abran said. Sweet looking unit tho, I would love to have one for airing up my tires.

 

Hmmm seems like my teenage logic has flawed me. Heres my second idea. Redundancy. I have been reading that the 06 models had a unused hole in the air tank. What about plumbing a backup compressor to the tank for emergency use. Would this even work if the compressor failed? In my head again I see it working. Much of this is just toying around with ideas in my head. One reason why I love this new rig is the endless things you can do to it.

 

I just bought all the fittings to add a Schraeder valve to that port. I’m planning on eventually mounting a second tank linked to that port. And I will add the Schraeder valve to that tank for emergency air up.

The OEM compressor would need to run longer to get the initial pressure up but once it’s pumped up it should function normally.

I have an ARB compressor mounted under my hood for airing up tires which could also be used to air up the tank through the Schraeder valve.

 

I would really like to learn more about the exhaust valve that is integrated into the compressor. Love learning about this kind of stuff.... Whats my best bet for finding info or technical diagrams on the compressor. Rave is currently downloading but is taking forever lol.

 

@memphis_rover for God's sake kid, go drink beer and party!

Don't over-think the EAS, it is more stout than you think. The LR3 is fun AF, enjoy it on the trails.

 

I leave plenty time for fun and this car is great for getting far enough out there that even the police f150s cant get to us

But with most of my credits already done I get to leave school early so plenty of time for rover mods. Loving senior year.

This idea of plumbing into the tank is appealing to me...

From what I have read if the compressor were to die I could use the backup just fine. As the general consensus is as long as the tank has pressure the valve block doesn't really care where the air is coming from. Almost makes me wonder if theres a way to turn off the factory compressor via switch, leave it in place and all the plumbing and then use the ARB to air up the tank. Again you run into the automation issue and in the end more effort than its worth.

My issue is once I get an idea in my head its hard to rid of it. Even if the end result just complicates things. Must be why I love rovers so much, the engineering always looks good on paper to rover, but we can never much understand what in the hell they were thinking on that island across the pond.
