ARCHIVE Wits' End York On-Board-Air Schematic and Discussion

[NLXTACY]

This is the air intake on the #viair #400C compressor. Since this is a sealed unit it can be mounted outside of the truck. But it still needs dry air to run properly. So much like extending your Axle breathers, you extended the compressors breather. You do this for both Viair and ARB.
The fitting that is supplied is a chromed 1/4" NPT fitting with a 1/4" barbed nipple. This is fine I suppose. But this uses the inside of the 3/8" Nylon tube and it's also not a consistent style of fitting and connection as the rest of the OBA system so I'm switching it out instead to the Norgren push fitting where the Nylon tube goes inside the fitting. This also gives me the opportunity to run a 90* elbow.

The #Viair breather itself is fine. I don't have an opinion either way. But the breather has a formed 1/4" NPT MALE fitting. Well I don't have a 1/4" NPT female push to connect fittings so for now I'll have to run the fitting that came with it. Yeah, I'm like the push to connect fittings a lot better.

One of the biggest tasks you will have when installing your own On Board Air system is eventually going to require actually running the hose/tube. The issue is often where to run it, how to get from here to there? Should I run the line they the chassis? All good questions but it's really up to your individual build and setup. But one thing that can be a pain to decide is how to support the new line(s) well you could just run the Nylon tube against the fuel lines or brake lines and just zip-tie it which is fine, I suppose. But it can be hard to give it a clean look that way.

Often I'll see P-clips being used. Those steel bent pieces of metal in a "P" formation that has a hole so you can use a screw to secure the clamp and therefore the tube. But...that means drilling...holes. Lots of them.

That sucks so instead I'm going to be supplying and using 3/8" kwik clips. These have a foam adhesive on the back, and after I clean the grease/dirt from the chassis/body, I can just stick these where I need them. Nice and strong and NO HOLES!

Dude! I'm trying to be patient but I suck at it!! Update on the bracket and air tank kit? Also the manifold block w/attachments?

Still waiting on the fittings for the York also. I know you're a busy guy but this money I've saved for this is burning a hole in my pocket! Hurry or I might spend it on another mod!!

In all seriousness, any timeframe to releasing this stuff? Thanks for any info.

Bueller, Bueller,.....@NLXTACY?!?!?

Aw shoot I missed your previous post. It's all happening. I'm waiting on brackets and in the meantime I'm assembling the final pieces for Battery Disconnect Mount.

I'll post the pieces up maybe tonight and do a newsletter. Right now I'm just cranking along.

And I just NOW realized I didn't send you that intake hose @Razorbackcruiser Ugh.

I'm assuming that I can add to the the bracket kit down the road...

Would like just air, then auxiliary tank then locker ....

I'm doing a la carte and kits so no worries.

Sorry everyone. I've been focused on four different product developments so time is stretched thin. I did want to show the suction hoses that go from the York to the air canister. I have been working with both Parker and Norgren to simplify the setup and parts have been going back and forth trying to find a solution that doesn't require a 12 week lead time or a 100 unit min. order

Here is where these stand for o-ring or rotolock (and no I don't have prices yet). I realized that all of the o-rings I ordered are incorrect so I need to order up a new batch.

 

[NLXTACY]

I also worked out a VIAIR compressor upgrade kit for the wiring and the air intake.

 

[NLXTACY]

I finally have the fittings for the York suction and discharge ports! This is a HUGE deal because it means I'm not forced using a stupidly overkill Aeroquip/Parker fitting with stupidly overkill hose that is unnecessary. I'll have pricing shortly.

Looks good. Glad it is all coming together.

Sloooooowly.

The York fittings have been doing well now. I got one report of the fitting leaking. He switch from the tape to liquid sealant and that took care of the issue. I also have the pass-thru on the air canister all worked out. Just waiting for the big ass roll of hose to get here so I can start chopping things up.

 

[NLXTACY]

Also, I changed a couple of things on the air manifold and bracket so I think I am at a happy place. I am just waiting on the prototype to be done and picked up so I can test fit and pull the trigger. I now have the relay and the fuse as part of the air manifold so that its as bolt-on as I can possibly make it.

 

[NLXTACY]

I have a couple of people now trying to get a suction side solution going WITH the PAIR eliminated air canisters. There is a roughly 1" tube that is now open. I'm trying to think of a clean way to use that tube (it has an exterior crimp seam) and convert it to a 1/2" barbed nipple. Ultimately I could run something on the lathe out of aluminum and mill in a keyway for the seam but it would still need to seal reliably. Any thoughts?

Cool idea, but will the engine suction do anything to pump?

Both will draw from the same available clean air. IF both the York was running (clutch on) AND the motor was WOT then *maybe* I could see perhaps an air volume issue but it's highly doubtful.

 

[thatcabledude]

So when the hand throttle is set there will be no chance of the engine sucking the pump into counter rotation making the belt squeal and no risk of the tank imploding? That's great.
