LEGO Technic 42008 Service Truck Review



While many of you may be familiar with the ever so popular Lego city sets and Lego Star Wars sets, do you know much about the technic sets with amazing power functions? If not, you really are missing out on something exciting from Lego. Today, we are here to introduce you to the Lego 42008 set, which is basically a large green Technic truck. What caught our attention was the speculated functions nesting behind this truck – they really did sound promising.


Story of the Model

When a vehicle is broke down, you can use this heavy-duty Lego Technic Service truck to make that rescue – it has a large amount of realistic power functions on it. You can extend and raise the adjustable crane arm or extend the rear outriggers. Then, you can lower the hook (it has a working winch), unfold the rear wheel lift and process to loading the vehicle you plan on towing.

This is a pretty cool 2-in-1 Service Truck that also feature 8 wheels, and a hydraulic lifting elements. Looking at it, we feel almost like we’re looking at the real thing here. It rebuilds into a truck with a crane that is capable of raising and lowering.


The Box

The Lego 42008 set comes packed inside of a fairly large box.

Here’s a picture of the front of the box. Looking at it, doesn’t it look like something that would catch your eyes? If you have a thing for trucks, it would definitely capture your attention.



Flipping over the box to the back, we find some interesting features that make us want it even more.

Here’s a picture we took of the back of the box – doesn’t this make the entire scenario look even more interesting? Here, Lego shows the features off.



Lego instructions

Inside the box, you’ll have three separate manuals. We have dealt with Lego sets that only contained one manual before and personally, we don’t like that because sometimes, we build our sets with a partner. When you have a partner, it’s hard to work on different areas using the same book. When there’s only one book, we usually end up making copies of the book so that we can work out of separate books. We were happy to find we don’t have to make copies while working on this set, because it actually comes with three separate instruction manuals. While we worked in Book 1, our friend worked in Book 2

  • Book 1 has a total of 75 pages.
  • Book 2 has a total of 64 pages.
  • Book 3 has a total of 61 pages.


Here’s a picture of the three Lego instruction manuals that come with this set.



The Build


The build was pretty straightforward and the Lego instructions were easy to follow, so we didn’t really have any problems putting it together. Overall, it took us around five hours, which we spread out over a week. Yes, there are some people that can sit down and put it all together in one session, but we personally cannot spare 5 hours all at one time, plus we’d end up getting a headache, so we highly recommend spreading the build sessions out.

Surprising enough, this is the first build we have done that combines power functions and pneumatics, so we were a bit interested in finding out how it all worked.

We like how there’s a lot of moving parts that aren’t all gears. Take the linear actuators as an example – those are combined with pneumatic cylinders and they leave a decent compact assortment of moving beams.

In this picture, you can see what the shade of blue, green and red that is used in this set:



Once you have the green paneling framed around it, it will start to take the form of a truck and this is where the real fun starts to take place.

In this set, you’re going to come across two distinct colors – green and red. Looking at them, we got that “Christmassy” feel if you know what we mean. With these two different colors, while building the truck, we felt as if we were building two different trucks (one inside of the other). First, all of the red beams were used up during the inner workings of the truck, then once those red beams are gone, you’ll move forward to working on the green beams. The green beams are for the outside paneling. In all honesty, the green parts were our favorites. In fact, while putting this build together, we found ourselves counting the number of pages before we would get to start using the pretty green bricks.

When it comes to stickers, sometimes we like applying them to our builds, other times, applying them feels tedious. In this case, applying the stickers to our build was pretty fun. With this model, there were a large amount of stickers that needed to be applied. For example, all three of the 11x3 curved panels have stickers, and 4 out of 5 of the 5x11 panels have them. Even on the side mirrors, you’ll find that you have to place stickers and personally we feel this isn’t needed, because most of the time, you can’t even see the side mirrors, but that is okay.

We came across something that surprised us – something we don’t recall ever seeing before and that was an error in the Lego instructions. When you have this set in front of you, pick up book one and flip to page 60. Take a look at the parts list – it says there are two motors required, when it is obvious that you only need one …it only comes with one motor, after all. By now, they may have fixed this error.



We haven’t used pneumatic parts in quite some time and feel that they have evolved since we last used them. We also noticed that the tubing has been pre-cut to the right size, whereas in the past, when we used it, we would have to manually cut them ourselves, so this is a major benefit.

During the build, you’ll discover a tiny spring-less pump – it’s spring-less because it has been designed to be driven by a motor, which we find it much faster.

Once the build was complete, we couldn’t help but to notice the piston pump was making some interesting noises. It could have been because it was banging into parts that was around it or maybe the internal parts of the pump were banging together, we’re not sure, but there was definitely some noise.





Due to the combination of power and pneumatics, the functions of this Lego set can be a tad bit on the confusing side because the switches work differently. You have two power function switches that are responsible for offering four different position, then you have two pneumatic switches.

One of those power function switches is responsible for enabling the pneumatic switches. The direction you place the power switch determines the direction the three power driven functions go. In regards to the pneumatic functions, this doesn’t really matter as the direction of the pneumatic switch that is responsible for determining which direction they move.

Here’s a list of the five different operations you have:

  • Power Function – hook extended/retracted
  • Power Function – rear stabilizer extended/retracted
  • Power Function – lift arm raised/lowered
  • Pneumatic Function – lift-arm extended/retracted
  • Pneumatic Function – under-lift raised/lowered


It’s pretty cool finding a Lego set that has this much playability.




Overall, we had a lot of fun putting this truck together and must say, it looks good once it is all placed together. We adore the colors. We tried to find images of the real-life truck as it’s supposed to represent it, but we couldn’t find it, so we’re not sure if the colors are real or not. The new tiny panels are pretty cool and make for detailed paneling.

Do we like it? Of course we do. Before this set, we put together three other Lego sets – Lego 42009, Lego 75827 and Lego 75149 and this one right here (Lego 42008) was our favorite. The build is fun and the playability is a major bonus – if you enjoy Lego sets with technic builds, this one right here is highly recommended.


Here, we’re going to leave you off with some pictures of this model:
