42043 - MB Arocs 3245 Mods and Improvements

Recommended Posts

today i have used jims gorgeous review to replicate the rear axles of the arocs. And iam not really satisfied. Maybe i have made errors because i had no instruction but it seems that the axle doesnt uses the full spring movement and the sideways guidance isnt the best too. so i have played a bit around. it seems to have more suspension travel and to be more flat.

Doesn't this use incorrect geometry? Because distance between the two axles is fixed, shouldn't the top pivots of the steering arms allow for some movement?

Efferman the problem is that the wishbones are used as leafsprings! and the leafsprings are missed! I've made some leafsprings with lego parts, will upload them soon

oh okay... wonder why TLG decided to go with flexible connectors though..

Thx for the ldd file, complete newb here to LDD and decided to mess around with the rear tailight section and modify it a bit....this is what I was able to come up with, hope you don't mind..

Here's the ldd file

Tlg has the suspension arms at a different location which makes this necessary.

I think the tail of your version looks to much like an M.A.N

True, I can see that. It was loosely based on this image, but after looking at a few more It seems that it wasn't very accurate.

Nice mods and added detail to the back of the model! I am not really used to new technic so once I get this model I'll have to watch on how new technic is used since I have not used technic since 2003-05.

Quick Question when does the official set actually come out because I have seen multiply release dates (Sorry to have an off-topic question).

Cool Designs!

Efferman, it would be nice if you use te round fenders from shapeways for the rear.

two mods, one for playability, one for stability.

The stability mod is for the stabilizers. it chanches a blue 2L crossaxle pin into an dark grey 3L crossaxlepin and moves a 4L liftarm. This should increase the stability of the wormgear mechanism.

The second mod is moving the pneumatic valves behind the batterybox to have all crane controls at one place. Unfortunately this makes it necessary to move the crane two studs back to avoid a collision between valves and crane column

Hi Guys,

as I don't like pneumatics, I decided to build it a bit different... meaning without the pneumatic parts (I know it's a sacrileg for all of you, who have waited decades for the new pneumatic parts:-)). And I also built a trailer for it...

The Truck is drivable and steerable via RC and also the dumping of the bed is remote controlled.

The trailers bed can be dumped manually.

I do not have the Arocs yet but i want to change te places of the 2e axle and the gearbox with the outriggers, then there is enough space at the back to add a hook lift. I can't wait.
