Unimog u1300

[Kiwimogger]

Hello all, i have been looking at an ex army 1300 with 20000km no turbo, no fast axles and a 75000km with turbo and fast axles. My question, does it matter about the k's and is it really that much of a difference having turbo and fast axles. It sounds like they still do the same speed. True or false? Look forward to any thoughts.

As far as the engine goes 75000km is nothing with proper maintenance. I will let the Mog guys chime in on the rest of the drive train. You want the turbo.

The lack of a turbo may or may not be important, depending on the altitudes you intend to operate at. A naturally-aspirated engine will lose 3% of its horsepower for each 1000 foot increase in altitude. If you'll be staying near sea level, no worries. But if you operate frequently above 5000 feet, the loss in horsepower may make the already modest performance of your truck too weak to be enjoyable. My 416 Mog camper really suffered as the altitudes increased.

Wether or not you can live with or without a turbo and or fast axles is purely up to you and how you intend to use the truck. There is a huge difference in performance and comfort with the addition of a turbo, fast axles too. You can always add a turbo, and instead of changing out the axle gears, wich you could do, you could always add a Class overdrive between the trans and the engine.
As far as the Km on the clock, as long as it's been properly cared for, I wouldn't worry about it a bit.

Id go for the turbo and fast axles. Honestly, before adding our CLAAS, our truck was fun, but kinda tedious to drive long distances, and that was with turbo and fast axles. It all depends on where you are going and what you are intending on doing with the vehicle of course. I think when we start our trip and get south of the border, I'll care less about those 'amenities', but they are nice to have domestically. In regards to the turbo though, thats a relatively underpowered vehicle when it comes to hill climbs etc, worse without the turbo. Many folks with a turbo still do fuel pump upgrades to get a little more juice.

All said, Id look at the rest of the truck. Rust, evidence of wear, how do they sound and run. Also, how easy to shift in between gears, particularly 4th to 5th. If all of those are about equal, definitely go for the fast axles and turbo.

Thank you everyone for your reply's.

We went out for a drive today and of course it was a little ruff in the gears until the oil warmed up and correct air pressure. Pretty clean.

It was mentioned that a bearing maybe warn in the gearbox, is this a major?

Hi All,

What other major things would you look for, other than corrosion.

Hi Sandy !

it is good to see some evidence of it's history. These vehicles typically are workhorses and thus have log books and service records. If possible try and find out what it ''used to do'' that will also give you an idea of how much wear and tear it has been exposed to . for example, fire tender mogs are the best as they are highly serviced with low kms typically , ex army ambulances also excellently maintained and small loads and low ams.

Portal axles / hubs need looking at as they are one of the most important systems / components on the mog.

i am currently based in the big sand pit that is dubai too !

cheers

Thank you for info.

There are a few little issues, which need sorting.

Cheers

We bought a non-turbo 1300, but very quickly got a turbo added. we would like fast axles, 65kph is our cruise speed to keep the revs between 2000 and 2200 which is the volume at which we can have a conversation

I have a non-turbo, now with turbo, overdrive, 365/80 tires and a pile of soundproofing. I cruise at 85 and it's comfortable. Overall drivetrain condition is important. A good OM366A is 1st prize as the engine can easily be tweaked to 200hp. Add a working group if you intend doing slow offroad work - it provides lots of control.

I'm with the others that a turbo and fast axles makes a world of difference in traveling with the U1300.

Concerning the transmission shifting, was the problem perhaps with the 4th to 5th shift? If so, that's typical of the U1300 when cold unless you upgrade the trans lube. If you had trouble shifting other gears, then that's a warning sign, especially if the seller suggested worn gears.

A transmission rebuild can be a huge expense if hired out, and parts can add up if you do it yourself. Be prepared to handle heavy stuff!!
