Air shift question

[chuck500cc]

I have flipped the switch on the dash on my M35 a couple of time for the air shift front axle. But should there some sort of clunk or something other than the light coming on. Will it "crow hop" like a regular 4x4? When I have flipped the switch it gives me no other indicators the front axle is engauged. When I flip it back to "out" I get a PFFFT of air from the switch.

Thanks

well if yours is busted then so is mine, i get exactly the same thing. On= Light, Off = Psssssst. Think its right

Were you moving when you engaged the front or sitting still?

I can't hear anything shift when I flip the switch on mine either (I've only flipped it sitting still). I know for a fact mine works . I've seen the front wheels spin .

My 6x6 works no probs but now I have to find this light, hmmmmmm wheres the light, follow the light im walking towards the light zzzzzzzzzzzzppppttt SH!!T bug zapper you gotta watch those so wheres this light hmmmm................

its only a dinky little red light, right on the panel that the swich is part of, kinda hard to even tell what it is when its not lit up

 

[chuck500cc]

mine is on the switch and is bright..

 

[scooter01922]

it is indeed bright, but still kinda dinky

Bright eh better get my shades!!! I plan on taking the ole girl out this weekend so hopefully I will see this phenominom then!

I do hear a light clunk when mine engages. The steering wheel should flight you in hard turns with the front axle shifted on. If it feels the same as when off, then you have a problem.

If you'll try it with full air pressure but the engine off and ignition on you'll here a clunk from down under the floor board, not real loud.

The test for air shift is pretty much the same for spraq units. Jack up one tire and with the switch indicating Locked In, see if the one tire off of the ground will turn more than about 45 degrees. There will always be some play. If it turns without locking up at all, then the tranfsercase output is bad or some problem exists in the diff. For Spraq units, in a forward gear the tire off of the ground will start to rotate backwards and then lock up, with the transmission in reverse, the tire will start to rotate forwards and lock up. Spraqs work on the rear wheels slipping in respect to the fronts and that's why it seems backwards for testing them.

Bury the Rear, Flip the switch, see if it works......Well at least thats how I found out mine worked.....

Just have "Plan B" in case it doesnt.

Mine has a light on it,next to the air shift switch, with a light kinda like the high beam indicator light on the same bracket as the switch. You generally don't hear much of a clunk engaging, but the truck will fight you on very sharp turns ("Traction Steer, I Guess?) and you will notice an increase in her pulling power. This baby's almost as good as the transfer case on the Unimog, and a lot less pain to use when it's working right. HOWEVER.... If you do get stuck in a deuce (particularly one Wo/W), life will get worse before it get's better........ The pulling ability of these trucks when they have good footing is quite amazing (I know- I pulled a phone pole outta line about a 1-1/2' unsticking a farm tractor)............
Uncle Sam did pretty well when he designed the deuce.... I doubt if the FMTV's will be anywhere nearly as useful in their 30's and 40's...... about the only thing that would've improved it would have been seriously designed locking differentials.... like the Unimog's!!
Just my worth.... (and who bothers to pick up anymore?)
