I need some spec's on ZF axles out of a Military Tug. They have 4 wheel steer but I don't know anything else. Any help would be appreciated.
 
They have some insane reduction ratio and are ridiculously heavy. Basically, you don't want 'em.
 
Yeah, they're insanely low geared. Don't quote me on this but I think I was told one time that they're in the 20ish:1 range. Yes, even if cheap, don't bother. A pair of steering rockies would be a way better investment.
 
Yes, they are known as "geared hub" axles. 21:1 sounds about right from what I recall. Search way on back, they have been discussed numerous times over the last several years...
 
how heavy are the axles? dont the tugs come with some kind of linked suspension?

They are called "planetary hubs" have the steering ram built into the housing and have wet brakes. They are better suited to tires in the 60" plus range. They are also expensive to maintain.

Perhaps some do, but the ZF axles under the Chevy-bodied aircraft tugs have the axles solid mounted to the frame.
 
You're right, my memory fails in old age. Planetarie hubs it is, I knew "geared hubs" didn't sound right, but couldn't think of anything else once it got hung in my head...

But you ain't old yet, but you're getting prepared for what is to come.
