Tell me more about the air cylinder locker actuation setup. How is it attaching to the diff housing? Did you machine an extension shaft that attaches to the fork?

I used this cylinder from automationdirect http://www.automationdirect.com/adc...inders_(C-Series)/1-1-z-16_inch_Bore/C170075D
I drilled and tapped the Toyota housing for the 6-32 machine screws that go through the cylinder and added a spring inside the cylinder to give it a default return function. I then had a shaft machined to mimic the e-locker shaft, that was threaded to fit the cylinder. I have about $80 in the cylinder, switch and fittings. My dad did the machine work on the shaft so that didn't cost me anything... yet.
Wow! That is elegantly simple and has such a low profile. Ash had suggested the idea last year, butI ended up buying an OEM actuator for $600. I think I will just resell the OEM actuator and go this route, now that you demonstrated it is a only matter of machining a shaft and tapping the housing.
The OEM actuator is a one of the poorest designed Toyota components that I have seen.
Agreed, this design is so snug and low profile, I am won over.
How did you integrate the return spring? It looks like you blocked off the air port for the return,,
Did you use the 3/4" or 1/2" stroke? the one you linked to is the 3/4". The actual travel length is just under 1/2"

sexy indeed.....Terrill is putting off home projects for too long
Do you mind pointing me to the spring you used? If your dad is up for it, I would be more than happy to pay him a fair price to make me 2 shafts like yours?
I think Terrill just found a side-job. Buddy, you could sell kits and 80 people would drink them up faster than Shiner Bock.

Sshh!!
I have an extra spring. I picked them up from Ace hardware and I have the drawing for the shaft. Granger has the springs but they had to be ordered and patience is not one of my virtues. http://www.grainger.com/product/Com...m/rp/s/is/image/Grainger/1NCD3_AS01?$smthumb$
and a link to the valves I am using for this and my front ARB http://www.grainger.com/product/ARO...m/rp/s/is/image/Grainger/3NB16_AS01?$smthumb$
I'll inquire as to a fair market price for the shafts.

I think it is marketable. Would need to be a bolt in package mounted to a plate that replaced the actuator and it would only work if the 8" version uses the same type of actuation/linear movement for the front axle.
It would need to be a complete package for wide spread koolaid consumption to take place
Thanks!
I think I will use this valve to keep with the FJ40's push pull switch theme:

It could also support the cylinders double acting capability for a pressure unlock

With your skills I don't see a problem. Even if you stuck to the 9" locker, and ignored the hi-pinion initially, you would sell thousands of them.
There was a mudd member, Amaurer, who made such a thing, but I think he stopped that business.
