ARCHIVE On Board Air Kits ala Wits' End...still working out da bugs

[NLXTACY]

Lots of stuff getting completed and off my plate finally. But lots of hiccups along the way. The York OBA Kits are in shipping purgatory, the SB50 cables are waiting on sleeving, the D-Pillar is waiting on time from machine shop to bust me out another proto, all lockboxes have left the building, etc etc. So I found myself with larger pockets of extra time. Knowing the York Kits were close to being done and shipped out I knew I need to get going on the rest of the kits. So I've been ordering just tons and tons of different components and pieces and fittings and stuff to make up the kits the way I REALLY think most could benefit.

BUT...I'm no expert. So now is the time for some feedback and to let you all know where this currently is. After installing three other OBA setups I've learned a ton and I am looking to not repeat those and other mistakes so that the kits I am finally able to offer will be nearly as plug and play as I can possibly get it without any worry about the effectiveness.

There are at least two things I wanted to go over and get some feedback on. One is the air tank and the other is the air manifold. First some background...

OBA (On Board Air) is having on demand air ready for airing up tires mainly but can be repurposed for air tools and blowing up air mattresses, etc. The source for the air in the OBA can be from CO2, electric compressors or from belt driven compressors. The 1FZ has the luck of having a York 210 that can be mounted onto the PS of the motor that is made by companies such as...well...mine

Since the air can come from at least three sources, it now needs to be regulated and/or stored when needed. Most electric compressors are on-demand pumps with no air tank but built in regulator. Some larger units have tanks as part of the unit. What I am looking to make available is an air storage system and an air manifold setup that doesn't involve sourcing parts nor trying to figure out what, where, when, how and why.

Here you can see an atypical OBA schematic and is slightly overkill, kinda like our Cruisers:

My first bracket kit will be to mount the Viair (or similar) 2.5gallon air tank UNDER the truck where the spare tire used to be. Still have the spare there? Have dual gas tanks? Don't worry, other options are in the works. But this is going to be mounted under the truck using existing holes found in the chassis. This is a zoom-in of the air tank and a schematic view of its general location.

Here is a better illustration showing what it will actually look like as an installed piece with the components all hooked in:

Here is my cardboard mockup before going into steel before final prototyping:

Next up is the Air Manifold that will be mounted in the engine bay. The location will be on the inside fender closest to the air canister. At this time, this will be the only option until I can figure out something else for those of us that have that area repurposed, me included

Here is the schematic of the air manifold:

This takes the hot air from the YORK compressor OR from the electric compressor and it then gives you a place for a safety check valve, a low-pressure cut-off switch, an air pressure gauge, an unregulated air port and finally the fitting to route the compressor actually to the tank.

Here is a mockup of the manifold with everything screwed in:

Here is the mockup of the bracket to mount the manifold along with the etching that will appear:

This will also house the relay and fuse required for the York Compressor but also used in electric compressor set ups that are hard wired.

Right now I am working on eliminating reducers and finalizing best (for the money) components I can find. Once these are finalized and I am happy with all the components I will move over to the coalescing filter and bracket and the intake/suction hose also for the York but not needed for electric compressors.

Looks good. Patiently waiting....

Now you just need one for the 3FE!!!!

It's an 80 thing. Motor shouldn't make a difference.

Joey,

Have you thought about replacing the check valve (not for safety, you already have a safety popoff valve) with an "unloader" valve? This unloads the line between the york and the manifold after the york stop turning and you get that, wait for it........SHOOOOOSH sound that's been known to produce minor chubs.....

There is an unloader valve in the mix. It's on the inlet port. I just need to get a 3/8" NPT version so that I can get rid of the reducer.

Gotcha

Alright... this is getting pretty cool. Thanks for putting all the work into this.
What is the best source for a 210? I was reading all the cars/trucks they came on.
Are they all the same?

Honestly I would call your local auto AC shop. They can get you a used one or a new one. Some new ones are Chinese. It's a non-start for me but it may be no big deal because it's not needed for 100% duty cycle. My local AC shop, no previous relationship, has a few used and a few new. I called two other shops and they can either get the used rebuilt or can get new.

Cool thanks. Bought a PUMA and LandCruiser Phil's mount a couple years ago and love it. I am rooting on the sidelines for this.

Marker for updates. Damn Prinsu rack might be cutting into my OBA kit

Might be cutting into my development. I feel ya.

So, the compressor bracket to hang it on the motor is the same?

Thats not what I am talking about in this thread. This thread is the OTHER pieces needed such as the tank/bracket and the air manifold/bracket. Those two things don't care which motor you have...as far as I can tell

For the ARB folk under the winch (I have an m12000 in mine) you can fit a 2 gallon tank. All I needed was to make a cross bracket with some right angle steel and weld a few tabs etc. So, that's one mounting location/option with a slightly smaller tank.

cheers,
george.

Thanks George!

I have something in the works to work in the 2.5 but I have reserved myself to the fact that it may be the 2.0

Still monkeying around with it.

Looking forward to seeing how this works out....specifically the manifold mount and bracket. I have my dual battery, washer relocation, charging relay and other fuses over there already.

Look at the space between the air filter canister and the fender. There.
