I composed a simple rudder setup for the tail: For me it is not necessary to have a fixpoint at the lower end: I have also reduced the unsightly hole in the wings by adding a 1/2 beam (7M) to the 'flaps':

I like what you have improved on the offical set.

The truck is tiny compared to 42128 Tow Truck: It'll also look funny compared to the Volvo truck from 42175. It would matter less if there was only one rear axle as a doule axle indicates a heavy duty truck. On the suggestion of using 49 mm truck tyres: - bigger cabin (orange one is adapted from 8052) - overall width increase from 13L to 15L. However, I think the model has potential for improvement: Because of the 19L and 13L frames the truck chassis does not need many parts: I think it should be feasible to drop the 3x5L lever on the tipping mechanism and move the linear actuator to the upper tier: The left setup works fine for me. The relocation would free space to add a differential on rear axle(s). In the cabin seems to be space to add a 4-cylinder fake engine.

From your Studio file above: There are two 11L beams used for the steered axle. I believe these are too long. I have used 9L ones. It's not easily seem from your rendering but better from below in the digital model that the front wheels are protunding.

That'll improve the tipping 'process': with two 12-tooth gear as shown in my picture above it feels to take ages between the two end positions. Nice. How did you find out about the interior of the cabin? (I gave up) I think there is a brown axle used for door not the red 3L axle-pin-with friction

Steering setup could be pretty basic: (I don't have the 13L frame) The most surprising so far appears to be the wheel cover (from small Bugatti, Part 2459 - new in black?) that is mounted askew. The cabin is simple, effective and stable. The front basically is a sheet on its own. Why do they use this part in black on the door? It's available from the Ford in Dark/Earth Blue. Truck appears - too - dark and dull with dark grey. I decided to add a streak of colour to it:

I believe this could work: Na, it'sprobably four frames: two 19L in the back and two 13 long at the front. (but yes: two left, two right)

Thanks. Please see the Pneumatics section..

I would like to show a modification of the original truck that has been on my mind for a long time. Only in the past weeks I was motivated to build it. I wanted a shorter version of the truck. Instead of keeping all of the functions and try to squeeze them in a smaller space the idea was to drop them: No third rear axle No raise/lower function to the remaining ones simplify the crane: no raise/lower no extension no rotation Side outriggers are not necessary This is where i started And this is the current state (as shown above): I kept the front (left to the green line) and rear section (right of the blue line) from the original truck. All of the mentioned functions were removed and the two units connected: The lime beams, red 3L pins, and 6x4 grey angle beams indicate the new connections. Then I have buildthe rear of the cab. The funnel has been placed behind as there was no space in its original position (I wanted to use the 3x11 curved shell). The final truck is shorter by 14 studs than the 42128 set: Changes on the decorative parts have been made because I don't have the second set of all the required elements.

I could be beneficial to bracket the suggested gears: The extra gears may prevent the load bearing ones to be pushed apart. If you push either of the axles towards the center I'll notice increased resistance on the rotation. so any pushing force towards the center of the gearbox should be avoided.

We had a small chat in the 2025 discussion a couple of days ago. Your chassis is different from my approach.

I've modified the box thing. It can fit a two-pump compressor and an air tank. Operation ist from the outside using a crank: For coupling the tube to the excavator I am using a modified version of this part: I used a small drill to open up in the middle.

It'll work with the known piece (71708): I've counted 81 parts:

I'm trying to put this truck together: There is an unfamiliar axle hole at the 'tip' of the red 3x1x2 quater ellipse piece

I have change the draft build from first picture to this. There is now a #1 connector

Thanks, that is very reasonable: It'll allow for a brown axle with stop for the worm gear drive. from 1st and 3rd counting: I am at 47 parts. + 4 tyres + 1 shovel = 52

I don't have the tyres and shovel at hand. I could not yet identify the lime part. (build with bright orange. reddish orange for comparison)

This is what i got: In step 269 the lever dost not reach its vertical position (cf. schematic up right) And this is what I did wrong: I misplaced the grey #1 connector.

Hello, I believe I also had trouble with the main gear not going working fully. If I remember correcty I misplaced {something} in the building steps 28 through 33. Did you check these?

According to Brickset theses parts are Bright not Reddish Orange.

Sorry for late reply: I don't see in your video when the motor stops as you have reported. From they noise I may guess that there is a little bit more fraction in your setup than in mine. I haven't heard of but perhaps there is an overload protection build into the motor?

0. This only happens if you select the fast rotation mode of the rotor? 1. Is the motor still running? You should hear a "whining" noise. 2. If the motor is running: There is a clutch installed. If the motor stalls because of too much friction the clutch will give a rattling noise (in addition to the motor)

Brickset lists it now with a set number: 412401.

Could there be other wheels / tires in addition to the mandatory amount of 49.5 x 20s to drive the vehicle? (I am thinking about the 49.5 x 14)

I checked my model: If no gear is selected - e.g neutral mode = none of 1, 2, 3, or 4 engaged - the pistons are not moving if the car is moved forward or backward
