Mercedes-Benz Arocs 8x8 chassis (unfinished MOC)

With the new big Technic set 42043 Mercedes-Benz Arocs coming to the stores I want to share my unfinished and abandoned Arocs.

Two years ago a Mercedes Trucks dealership in Spain asked me about built a Arocs 8x8 for them in big scale. When I had the chassis finished they decide don't buy me the truck, so I stopped the development, but I kept the chassis assembled because I didn't need the parts for other projects.

This is what I built (the chassis has tons of dust... but after two years on a shelf is normal ;) )


It is built in scale 1:11.

The overall chassis size is 29 studs wide and 90 studs of length.

Front axles

They are like the real Arocs, solid axles with leaf springs, disc brakes(yes, the real Arcos can have disc brakes in the front), complete ackerman steering with linkage mechanism.




The second axle includes two differentials: the second axle differential itself like another axle, and the central differential between the first and second axle. Just like the real Arocs.


6L engine. Now the truck has some parts missing, but after 2 years I have needed some of them to other proyects.

Here you can see the complete steering linkage system. The little linear actuator move the steering of both axles.



Rear axles

Again they have the same design as the real Arocs rear axles.


The third axle includes two differentials similar to the second one: the third axle differential itself and the central-rear differential.


The axles have 3-link suspension, again like the real Arocs, common leaf springs and drum brakes.






The complete assembly, including the main central differential with lock.


I am publishing this because probably I will never finish this truck, and now with so many people talking about the MB Arocs I think it is a good moment to show it. ;)

I hope some day you decide to finish this MOC. It would be a towering validation of your genius. It would be a true work of art. I am ready to build it. For something this beautiful, money is no object. Some day, maybe?

Do you have any type of instructions for the drum brakes?

Dehwei Hsu said...

can you take many many photos of this from many angles so that we can see how this beast works?

Fernado, esa maravilla no puede quedar en el olvido, y además cuando consiga fama mundial que
se fastidie el representante de los camiones Mercedes.

Un abrazo.

The set-up of this Super MOC is absolutely fabulous. I am working on 4 axle mobile tower crane. I start to realise how difficult it is to make a good looking and working set-up. Particularly this set-up is very nice because you are applying the large wheels, enabling the set-up of a SUPER MOC with a lot of power functions and details. A lot of details are included in your set-up like de breaks, etc. Please go on to complete this MOC.

Suggestion for a super MOC: make an auto trailer for the loading and transport of your cars (your lego main creations). Than you can really make a giant lego technic construction.

You did an amazing job and that chassis would look perfect on my lego technic crane

You can't fit this chassis in the 42043 set, this is built in different scale, it is much bigger
