Thread: CDL Air/Electric

You need to find a small air cylinder, that either has the right throw for the lever you have or make a lever to suit the throw of the cylinder. Needs to be double acting cylinder (air operation in both directions). Then the operating lever/button needs to runs the correct pattern to pressurise one side and vent the other and vice versa.

Not hard to do if I had the time and the catalogue I think I have in the garage. Need someone to confirm the distance that the standard lever for the cable moves at the centre of the hole for the pin.

Get me these and I can get you the Norgren part no's for the cylinder and operating mech plus fittings.

KISS principle is far better...

Get an Ashcroft Cable version

Thanks; I have no internals in my transfer case, but I have another transfer case arriving next week, I will measure up and work out the details when it arrives and PM you. Thanks for your input and help. Joe

Ok,

Bear in mind you'll also need an on board air source. For my ref, p66 2000 catalogue.

Norgren compact double acting cylinder, 12mm bore, 6mm rod. stroke 5-30mm in 5mm increments. 5mm port. Magnetic piston for switch operation, female thread.
Part RM/92012/M/*

* designates stroke length 005 to 030

Stud to adapt thread M/P1710/018
Clevis for stud (should fit over lever) QM/57008/25

Square cylinder, 25mm across, assorted mounting holes.

Magnetic switch available for activation led signal.

This is my airshifter - it's single action, self retracting with a helper spring. Some favour staying with cable actuators, but air rams work very reliably in this type of application as anybody with any experience with driving or servicing heavy road transport vehicles knows
The air supply is an ARB onboard air compressor the type used for diff lockers

Thanks for the post and pic.....Does you system have air on it all the time that it is engaged and when air is off it returns to disengage? Joe

Bob...

I used to handle this gear all the time...

Work really slick...

But still not as simple and solid as a cable system...

Yours looks slick, unsure I would want it spring return though.

Love it but how do you keep the mud/dust out?
