R1 Teardown

Pulled the bed out to run some wiring... What a pain in the ass.

Laser jamming?

‘Can you see if dirt get in behind the bumper, is there a way out for it from underneath? I assume they have drain for water.

It would just run out, it's all sloped.

pressure vessels require this information on their data plates.
wouldn’t be there if it didn’t have to be

Interesting. I've made many pressure vessels but in prototype/one off designs so didn't have these worries (although sometimes I don't accept jobs when high risk, just turned one down for pressurized hydrogen sulfide).

Doesn't seem to say ARB anywhere I can see without unbolting it, but it does say assembled in Australia.

That makes sense. ARB is an Australian company.

Looks identical to the ARB housing as well. I really doubt its the same though considering the temp monitoring and pressure control Rivian has. https://arbusa.com/site/wp-content/webp-express/webp-images/uploads/2018/10/Alpha-image.png.webp

Does the convenience compressor (in-bed hose connection) have temperature monitoring? We know the suspension compressor does but I didn’t know the other one does, too.

Good point. Are there 2 separate compressors or valving to do switch outlets?

I’m pretty sure there are two compressors. First, Land Rover does it this way. Of course as a new manufacturer there is no guarantee that Rivian will follow conventional wisdom. Beyond that there are two other pieces of info we’ve learned that make me think there are two independent systems.

First, people are complaining about the volume of air when they try to use air tools even though the air suspension system has a pressure tank which should reduce this issue if the systems were connected.

Second, the tank on the air suspension system has this sticker:

Aside from the fact that beach balls, tires, and rafts would fall under, “any other application,” the dry air part makes me think this is similar to the Land Rover system. In their system the suspension compressor draws in air through a desiccant, like silica gel. This is done to reduce the moisture in the entire system since there is no way to drain the pressure vessel like there is on many shop compressors. If you used the suspension system compressor to fill external items like tires, air mattresses, etc. then I think you’d saturate the desiccant and start introducing moisture into the air suspension system. Assuming Rivian handles this like Land Rover, dry air vented from the suspension system, like when lowering the vehicle, blows back across/through the desiccant to dry it back out for the next time the system has to draw air in.

I think I saw confirmation that there are fuse blocks in the Rivian but I haven’t seen a list of fuses. If we had a list that would probably settle this with some certainty of it shows two different compressors or even a fuse for the convenience compressor (or whatever the proper name is) in the bed with a relay, disable link, or fuse for the higher-power suspension compressor.

I could do more research if I had a Rivian of my own but that’s probably 12 months away so I’m relying on current owners to fill in some blanks.

I'll have to look at the fuse boxes and see if I can figure things out. The dessicant is interesting, seems like an active drying method would be needed. What if the pump activates when going through 3ft water? Does it have a remote intake above that level?
Interestingly, when I turned on the bed pump the first time, it shot out a significant amount of water (about 4 oz). Not sure if it was in the pump or hose.

On our Land Rover the air suspension air intake and breathers (for differentials, IIRC) are all above the max water fording height to prevent issues.

The desiccant seems to work pretty well, of course the dry climate here helps. England is known for being damp and I assume it worked fine there, too, provided there are no system leaks. If there is a leak and the compressor is regularly drawing in outside air without venting dry air then the desiccant can become saturated and useless.

At least on Land Rovers it seems like maintenance and timely repairs are key. The systems are complex enough that ignoring a small problem can turn into a big (expensive) problem. The Rivian suspension is more complex but without an engine, transmission, and three differentials I expect the Rivians will be easier to maintain.

Remember the bed compressor was to be an add-on option. And you can hear the little thing run when you use it. It has absolutely nothing to do with the suspension compression. And from the label you can see the suspension system is also 10x the pressure.

I am more concerned about pyro fuse that seems like much more difficult to get to. I have no idea how exactly it is triggered. Now I am afraid if I hit a speed bump the wrong way and that thing blows, it may have to be towed at least 150 miles away for disassembly. I don't know how to make sure it does not explode by accident, well, you know what I mean

I may have missed it, where is the pyro fuse?

Wrong! If you watch the Munroe teardown they show it underneath the class A driver side dashboard cover. It looks like a real pain in the ass to get to. If you tried to access in a hurry to override it you may face some expensive replacement. Really unthoughtful placement for a vehicle you are supposed to be able take out in nature. What if you hit a boulder or tree and it triggers? You one SOL MOFO
