I thought but i can't find the thread. Looking for something bigger then the u1300L

wolfgang has some u1550's (or he did?)... those are monsters!! heres a link!

They aren't much bigger then the u1300L and the same size for the most part. I'm looking for like the 10 lug bigger axles. I guess I need to find a place to research it to see what models are available.

One advantage of the U500 axles is you would not need pinion conversons. The U500 does not have torque tubes.

That'd be swell. Now I just have to find some. Are the u500 the biggest? They look about 90" wms. Does anyone know what the wheel stud bolt circle is? I think the 10 lug in the US is 285mm but i think europe uses a 335mm with a larger center bore too.

Just out of curiosity why do you need anything bigger than a U1300L? They are 84" wide and have 1.75" axle shafts before the portal. They are massive axles. IIRC they are ~700#'s stripped of excess brackets.

I know, I have a pair. Its getting closer to time to put them back under the truck, and i'm having second thoughts. Its a utility truck, with rock crawler attributes. I don't want to have to baby them.

I have a set of 1300L's, a couple 419's and a U1000 that I've been playing with for the past couple months and I'm amazed at just how massive these things are. I'm putting together parts for a 1 ton crew cab GMC truck with dual steer axles and knew the 60 and 404's were not going to cut it. After researching the 406-U1300L axles I realized they were overkill for what I needed but were still reasonably priced, and reasonable weight for what they are. My estimated weight is 8000#.

I'm used to dealing with large construction and mining equipment and normally when I look at 14 bolt or 60 stuff I'm impressed with what they can do for the size of the components.

Then I set the axle shaft and pinion of a 419 next to the 60 and 14 bolt stuff and it's just silly how much bigger it is AND it has a gear reduction after the diff.

I don't know what you're building but I'm surprised it needs more strength than the U1300l's.

One of the functions will put about 30k on the front axle. Compare a u1300L to a class 8 axle and it is a toothpick.
So does anyone have any tech?
Wasn't there a link to a chart with all the unimogs on it and the capacitys, and dims? I can't find it now.

Dunno, but the highest grossing weight for an entire U500 is 33k. I don't believe there's an unimog axle that will take 30k...

Unimog North America had 2 brand new rear axles for sale relatively cheap as spares for demos; no fronts (one could be ordered, but not cheap). It has a plated rating of 9000kg = 19845 lb. Practically a Class 8 axle, 20-23K is usual for OTR trucks for single axles. The bolt pattern is 10 on 335mm; the hub is 281mm. The distance bolt surface to surface is 2150mm ~ 84.7".
The front axle is plated at 7500kg = 16538 lb. The ratio for North America is 5.922, for the rest of the world 6.38
You could find Rockwell 5-ton axles or Class 8 OTR truck axles a lot cheaper and easier than U500s. What may I ask are you doing that requires massive load capacity and portals?

So, any ?s?
I can tell you a set of portal bearings and seals from a Detroit Diesel dealer is about $800/box. Even I just carry one set of bearings as spares. Also the necessary special tools.
