DANA 745 axle

Anybody have any input on these? They appear to be comparable to an Axletech. Trying to figure out if these are worth pursuing at work here. May be able to pick them up for scrap.

Looks like they come out of construction equipment, guessing military construction equipment. That's really all I can find at the moment.

Yeah, Intended for a front wheel assist tractor.

The print says they weigh 1190lbs(540KG) . Trim off the Unicorn horn and a few other little casting pieces, they're not much heavier than a 60.

Buy them for scarp price, dick with them to see if you want them. If they turn out to be turds, then sell them for scrap price with the satisfaction seeing what they are all about. I would guess that they would make a great axle for a trail rig with the exception of custom wheels unless they are too wide - most of the 'tractor' housings are cast like this and very tough to cut down and still be reliable. Tough to see the size without something familiar int he pictures.

Outside portal box is 2196,(86.5") Wheel surface is 1892(74.5") Has "Gruppo Dischi Blocco" which based on my awesome Italian and Google. Must be a locker of some sort.

I want them. Gonna push to make it happen, they've been sitting around awhile.

Get them for sure. 2.5 ton rocks are 79" WMS unless you flip the hubs so width isn't an issue.

Would be curious about gear ratio though being from equipment they could be in the 10.26 to 1 area. Worst case scenario you can run a 1 to 1 transfer case though.

Are the 60s you run encased in concrete or something? Stock trim early HP60s were in the mid 400# range, the GMs were just over 500#. Or so says the 60 bible. My AxleTech Portal equipped 60 and 14B together probably weigh just a little more than one of those things.

And those are planetaries, not portals.

Yup. Skyhook/gradeall boom lifts use a center pivot with a single. Ram mounted to one corner for suspension.

The gm mil tugs use a similar center pivot axle mount

No doubt its north of 10:1. Some planets are 22:1

Could the thing on the top be brake related?

Scrap is what, .03/lb right now?

$36/axle I'd jump all over it


Should be wet discs, and the integrated ram is handy. Doesnt look like as much steering angle as the axletechs, but as long as the parts arent too expensive, doesnt seem like a losing proposition.

you know, we have a navy tug at work. I forget the real name, but we call it the Buddha. We decommissioned them a few years ago. For moving c40's c130's etc. It's had the front end cut off so the axle is sitting there, ill have to see if it is the same. IIRC it had 2 rams for steering and has a ton of steering angle so it may be different.

They still run and at upwards of 30k lbs they are fun to run into other trashed vehicles.

I cant say that ive seen a shaft driven axle do it but the hydro drive wheel hubs can pigeon toe the tires and and do a nearly zero radius.

I will get some pics at work later, but those are similar to the axles on the MB4 aircraft tugs. They have double cardan steering joints, 4 wheel-full hydro steering, planetaries, a 6.7L cummins 6BT, some kinda hydrostatic transmission and 6" thick bumpers.

Yup. It costs me more to have a bin here than I make in the steel. I shouldnt have to pay to get rid of steel

To do this the wheels on opposite ends of the axle have to rotate in opposite directions. Check out the Jeep Hurricane concept from a few years ago to see a way to do it with shaft drives (but not a single solid axle at each end).

Are we talking about the same thing? I noticed I can turn the pinion yoke very easily, with one finger. The hubs do not spin when I turn it.

This is literally all in a trash pile and will stay here until the navy writes a contract with someone to come haul it away for scrap. I could go to jail if I made the motor disappear. It's still pretty tempting.
