Does the white black piece at the bottom act as a parking brake ?

Exactly. At least from what i understood :-D

drive follows the path of least resistance, so when the tipping function is engaged, the alternative path is to turn that clutch you describe. Thats harder than tipping the body, so directs drive to that function

now I’m thinking well I don’t know in any position the wheels never turn

Can anyone see the video ? Hoping it’s only Flickr lag

another try

 

 

Can't see the videos.

EDIT: 

I just went to your flickr account directly and was able to see the video. The first thing I noticed is that when you switched the orange part it just switched the position of the upper and lower driving ring. Not the one in the middle behind the orange part. I'll try to create some digital CAD pictures to provide a better understanding of the gearbox.

If thats the case then its just a case of revisiting the instructions - there's a page that clearly shows the engagement of the orange components. Go to that page and trouble shoot it based on @Andman diagnosis. Figuring it out will stand you in good stead for future lego projects... (and other areas of life!! ) ...seriously though, its just a problem solving task thats now been narrowed down considerably. Work through that area methodically and should be an easy fix.

Andman I have to visit flickr and fix that video but yes it does shift all 3 upper / lower and the one behind. I’ll have to retake the video at no time in does any movement of the drivetrain 

 

TeamThrifty I rebuilt the gearbox in my normal vehicle I drive it seems simpler ..

 

 

 

 

Newest video

can someone see in this video what’s wrong. I realized that I have to use link button above and not just copy paste it into the texf

You are missing the shaft that's need to bee mounted in step 66 of the manual. This one connects the gearbox with the central differential.

Are you expecting the rear axle to turn? This will not happen because the axle which drives the central diff between the gearbox and the motors is not installed. @benovitch, sorry didn't see your post. Should have updated the page before sending my post. Thanks for the detailed help.

Maybe the following image helps too.

Now I'm curious to build the set and see how difficult it would be for me to get it right... But I don't need the parts (except maybe the yellow ones) and it's far too expensive to get just for the building experience and testing :|

Link to more pics

the shaft he’s talking about is there it’s just under the dump mechanism

I’m baffeled taken it apart not 3 times don’t know what’s happening

You bought the wrong set.

It still looks like you are missing the axle installed in step 66. This axle is not visible in your latest video and in your latest pictures. This axle drives the central diff, which drives all axles. Please check again.

Ok I’m going to investigate, but I don’t have any extra pieces left over 

I see what’s missing now clearly strangely I don’t have the parts ... wonder what happened

Then they are missing in the set. Just contact Lego here: https://www.lego.com/en-us/service/replacementparts

I added the parts from spares I have from other sets. Now the engine spins when calibrating , but no movement of the vehicle ...

so path of least resistance ? Any pointers on where to look ?

 

i can post video

So when I spin any of the rear wheels the engine spins, and the other rear axle spins. Not however the front axle is this 6x6 or 6x4

 

thanks for all the help 

Hello,
my hauler is not at hand. Therefore i would like to suggest the following tests from another topic on the set:

Verify that you have aligned the differentials as shown in step 340 on page 219.

When I lay my hauler on its side and spin on of the rear wheels, the other rear wheel rotates in the same direction and the fronts wheels rotate in the opposite direction. The housing of the grey differential, e.g. the 24-tooth side of it, are visible from the bottom: It does not turn. 

(laying hauler on the side effectively blocks the second wheel on the axis and prevent them from spinning.)

If you got that far you could also set up the control+ hub: Put in the batteries (inset on page 222) and connect the cables as described in step 344 respectively 347.

If you start the control+ app a firmware update will be written to the hub. This can be recognized by the red / green / blue changing of the LED. If the hub is ready the indicator will change to a permanent blue. Select the interface for the hauler. It will open in the setup screen to calibrate the motor. This includes a backward / forward test drive. Do not worry: It will take less than the + / - 1 m space. My truck was moving only about 40-50 cm.
The calibation should finish sucessfully even though the linear actuators aren't connected yet. 

 

I guess the motor calibration will also work if hauler is (still) laying on on its side. This will give you the chance to see if differentials are moving.

By "engine" you are referring to the fake 6-cylinder motor in front of the truck? This is powered through the trucks front axles (see step 185 on page 118 (The drive input is added in step 204, p. 132, see inset).
Therefore, if cylinders are moving up and dwon, the front axle should turn as well.

 

 

Wow... just wow..

Patience, my friend :-)

@Jgooffer, Look at the image below I would say you are missing the parts installed at step 99 on page 60. Please check that first before posting images or videos. I would like to repeat what @TeamThrifty mentioned before. The Set is not flawed. You just have to carefully follow the instructions.

 

 

 

Not to mention most of those red 2L axles need to be pushed in properly.

Are you sure step 66 on page 42 has been done... the 5L axle and 2 yellow joiner things? I can't see it on his pic - it should be visible

I assume he confirmed it here. He didn't update/add any new pictures.

Well I have taken a few days off, still can’t get it to move after adding the missing shaft

Click here for newest pics

And here Video

so it all moves together now when I go to calibrate it doesn’t move it shifts the purple thing from 9 o’clock all the way around but the vehicle doesn’t move 

yes there are some stiffeners missing in the chassis will put them back once I get it to move
