Hello,


as far as i know the U1600 and U1400 are pretty close, but since they differ extremely in the gvw (7.5 to 10.0 t.) there has to be more than meets the eye.

The specs suggest, that the U1600 got wider axles which are stronger i guess and of course he's got a little more horsepower.

But is the frame the same, so is it still pretty much the frame used within the u424 u1000? Is the gearbox the same? The portals?

Greetings

A u1400 has 6 bolt hub axles and a standard 427 series frame (chassis). The U1600 has the same frame, but with serious factory reinforcement plates, gussets, ect., and has 10 bolt hub axles that are close to the same track width as the U1400. The cab, bed, ect are the same between the two models, and the engine is an OM366A in both (if they are both 427 series units), although the U1600 has a bit more power from the factory.

Cheers,
Ben

Chris,

A U1400 is just a U1200 with a power upgrade, if both the 1200 and 1400 are 427 series trucks, then the 1600 got more power and teh heavy axles. AFIK there wasn't a 1400 or 1600 in the 424 lineup.

Cheers,
Ben

Hello,

ok that makes sence and how close is the basic 427 frame, the one used on the U1400, to the U424 frame? Is it pretty much the same or a complete redesign?

But the 437 uses a completel diffrent chassis right?

Greetings

Remember that the only thing that stays consistant and that's the name Unimog. My 1250L is numbered as a "427". Who knew.

Right on the first count, but on the second, a 1250L is a later addition and a different animal than the 424 series of trucks. Just like a 1550 has noting to do with the original 1500 series. 437 vs 425.

There is actually a method to their madness. It's just complicated and you have to pay attention to the details and ignore special order trucks.

The only anomaly to the scheme that I have run across is the first generation 1300s. One version was a lower horsepower or perhaps non turbo variation on the 1500. That makes sense for the time, but there was also a 1300 of the time that was very similar to the well know 1300L with a lighter frame, 6 bolt hubs, longer wheelbase and more rear frame overhang (I think). It's kind of like they forgot to have a meeting about that one. I've never heard word of one in the flesh but it's on the books.
