Air shift install

[goodwithwood35]

Ok, so I've found myself a good take-out air shift TC to upgrade a badly leaking sprag that needs a rebuild anyway. I also found a front drive air switch. I've read a few threads on the upgrade and the actual TC swap looks pretty straightforward. I've searched the TMs, Internet, and this site and haven't found a good air system diagram and how the switch is plumbed into the air system. The electrical part (light) looks pretty straightforward. Can anyone help with plumbing/routing the air from under the dash to the TC? I want it to look as OE as possible as far as routing/materials goes. Maybe a pic or 2 of what it looks like? The switch has 2 air connections, one on the back and one on the side. I imagine I can build the lines myself or visit the local hose supplier and have them made. Thanks for your help gentlemen.

Oh and this is for a deuce, 1966 wo/w.

Even a bar napkin drawing would work LOL.

Thanks to OP for starting this thread. I am going to be doing the same thing. Convert sprague to air shift. I don't want to hijack the thread but is there a conversion kit with the hard parts? have the TC just need the bits and pieces. Perhaps the OP picked one up for this project.

I'm currently in the middle of this swap. I went ahead and bought the kit on the popular auction site. Comes with everything you need to do the swap well worth the $140

 

[goodwithwood35]

Thanks for all the replies thus far. I have the switch itself, had no idea a kit existed I figured it was sourcing the individual parts or DIY fabrication of air lines.

Easter Surplus has the above kit for $195. Didn't see any online anywhere else including auction sites.

I have been needing to do this also. The kit comes with copper tubing, can I use vinyl/plastic truck airline tubing instead?

 

[goodwithwood35]

I'm sure you could, I just wanted to keep it original as possible.

 

[two.fiveM35]

I just don't think I can bend and shape the tubing without kinking it.

 

[goodwithwood35]

I've successfully used brake line benders for this before, it ain't bad.

I have seen a couple different "kits" on the popular auction site you likely speak of. One looks to be a kit to rebuild the inerds of the TC internal air switch side. While the other one I was hesitant about because I could not for certain see the under dash switch. Any chance you could clue me as to a specific name/descriptor to "search for" regarding the kit?

Thanks Good with Wood. Looks like you are "rolling your own" so to speak regarding the parts to hook up the TC. I appreciate your feedback.

So you can get the air shift upgrade kit. I looked on eBay and didn't see any currently or even recently up.

The NSN for the kit is 2520-00-113-8049 and the part number is 5704132. Looks like:



Eastern has them for $195. I don't see them any cheaper anywhere else.

I have done several of these and I've bent air line (for customers who wanted a very correct upgrade) and I've done it with DOT airbrake tubing. I like the air brake tubing, much easier.



Bending the air line isn't difficult with a good tubing bender but it takes some practice to make your stuff look factory.

I found a kit on the bay for almost $400. I ended up ordering from Eastern Surplus for the price you stated above. I found an old thread that said Saturn Surplus had them, but I contacted them and they replied back saying they sold all their M35 inventory to Eastern.

 

[clinto]

I saw the $400 one. I like those guys, they have a lot of weird small parts.

 

[goodwithwood35]

If it came to a $400 price tag, I would have had to piece-mealed or DIY'd the entire system. I paid that for the TC itself.

Yes. In fact that is better then the copper lines.
