Model US Truck T2 MkII build with LEGO® and with LEGO® Power Functions® which is a rebuild and revised version of US Truck T2 I finished back in 2009. Like with all my models this is build in scale 1:17,5. This specific model comes with building instructions available at mocplans.com plus the inventory list available at rebrickable.com. This model features: solid axle suspension on all axles, PF powered driving with power transmitted independently to both rear axles, Ackermann geometry on steering axle, Servo powered steering, fully functional fifth wheel, modeled engine and 3 sets of PF lights.
About this creation


History of this build
To start with a little history on how this model was designed and developed in the first place and how US Truck T2 evolved into US Truck T2 MkII.
Back in 2008 I started building US Truck T2 after I had finally managed to build a very sufficient and realistic suspension system. From the very beginning of building MOCs I always tried to implement as many realistic features as possible. For example both version I and II of US Truck T2 features full solid axle suspension, Ackerman steering, realistic and working fifth wheel, openable hood, PF drive, PF steering and PF lights.




Design and development process
With the chassis still evolving, but good enough to start building the model itself a couple of decisions had to be made:
A) First of all I choose not to build a specific brand or type of truck. What I knew is that it had to be a typical US style truck. That has always been my favorite and it always will be. Inspired by all the amazing US truck brands I just started designing my own truck. Because of my love for work trucks specifically both the Kenworth C500 PDF and the Kenworth Work Truck PDF brochures available at Kenworth.com became my main inspiration source.
B) What scale to build in is another obvious quest when building models in general and also for building LEGO® models. Since most work trucks have a little bigger and heavier wheels my favorite scale for building models became scale of 1:17,5 because this suites me best. Also did I decide to build all my creations in this specific scale. To me it works great when models can be combined. Setting this scale I could move on to the modeling of the body work for this truck.
C) Setting these parameters the build actually started. I had to figure out what color scheme would work best for model US Truck T2. To start with I do not like building with Black colored items what would have been an obvious color for the chassis. For me Black is depressing and I want to be cheered up by building instead. Why exactly I can't recall but the chassis ended up Red and I still love it. With the color of the chassis pointed Red I could move on to the colors of the body work.
D) Searching the Internet for inspiration on this build I noticed that Red and White is a nice color combination. So White it is for the body work, but only White might be a little boring. Trying a couple of colors to combine with this evolving color scheme I ended up with Blue. Since not all parts I needed were available in Blue back then I came up with the use of Dark Blue. Sand Blue had to be used too for some other specific parts.




Why US Truck T2 MkII?
For me my first model US Truck T2 really stands for a new era. Not did I only start building with LEGO® again, I moved to another part of my country and started to live with the woman I love. Also did in time my building skills develop and so did many solutions. This model could be so much better if I would have build it these days.
Because of so many improvements I thought it would be so nice to rebuild this creation. Rebuilding this MOC made me decide to name this updated version US Truck T2 MkII (it is based on US Truck T2, but revised in so many ways). Thinking about the rebuild, not yet started, made me realize that it would also be amazing to make building instructions available for it as well! Since 2009 the year in which I finished US Truck T2 I have been asked for instructions so many times. Not only do people love the model, the interest in the suspension system is huge.
The process of creating instructions basically forced me to completely revise and rebuild it. So in the looks it is not even changed that much but to get the build going with the instructions as guideline I had to change so many things. Because of this process this new version is way much better and therefore very nice to build. This all together gave birth to US Truck T2 MkII and I am happy with both products: The revised truck itself and the instructions for it that will be available soon.




Solid axle suspension
As with all trucks and trailers US Truck T2 MkII is build with full solid axle suspension on all three axles including the front steered axle. The finished build of US Truck T2 back in March 2009 was basically a result of all the effort I had put in this realistic suspension system. For this suspension to work I did a lot of research, trial and error and engineering. One major problem I noticed was the quite large size of Technic® Shock Absorber 6.5L. There was no way I could jam six of these into a chassis that is only four studs wide together everything else that should be in there. So I had to approach this matter from a different angle. Quite rapidly I came up with the idea of using Rubber Belts instead. To achieve this the movement needed to be converted so I came up with a lever constructions. Normally a spring is pushed in and comes back, but a rubber belt is stretched and comes back.




Initial color scheme applied
In the build of US Truck T2 MkII I replaced the hard to get Sand Blue colored parts by Dark Blue ones. Back in 2009 part 30357 Plate Round Corner 3 x 3 wasn't available in either Blue or Dark Blue. These colors I did prefer back then with the build of US Truck T2. This forced me to use this part in the less common color Sand Blue. Even though this was a switch that worked out very well I prefer not to use this color. Mainly because parts in this color are hard to get. So now that these parts are available I had the chance to give US Truck T2 MkII the initial color scheme I came up with for the first build.




Updated steering system with Servo
A part that I have been looking out to for so many many years is finally available. The LEGO® Power Functions® Servo, item number 99498c01. This enables the opportunity to create a much more realistic steering system for US Truck T2 MkII (and for future builds as well of course) that is also less space consuming. Aligned with the trucks chassis the Servo is sitting inside of the cabin right behind the modeled engine.
Since the movement of the Servo needs to be converted 90 degrees a challenge occurred. A 90 degree angle in a rotating movement is easily achieved with bevel gears. But with the use of the newer bevel gears the LEGO® Technic axles are no longer aligned. Many applications do not require axle alignment, but this specify application does! Luckily we still have this older LEGO® part 4143 Technic Gear 14 Tooth Bevel. With this I was able to make a 90 degree angle in a rotating movement with the axles still aligned.




Modeled engine inside
As mentioned above the Servo requires less space compared to my earlier steering systems. Because of this US Truck T2 MkII is equipped with a modeled engine. As stated above the Servo is sitting inside of the cabin right behind the modeled engine (inspect picture to find in).
Because of some parts I needed to build this engine that are only available in Light Bluish Gray this became the engines color. So the color decision of this engine was easily made, but to be honest I prefer another color. Yellow would be so nice to emulate a CAT engine, but one has to dream of things to come.
Searching the web for inspiration I noticed Detroit Diesel has some very nice power sources available. Doing some research made me choose to build the DD15. Modeling this engine was very satisfying. A small object to build but to give a realistic look still a lot of parts are used to build it.




Openable hood
What is the use of a modeled engine if it is invisible. Like with the early version this revised model has an openable hood. For inspiration again I used the Kenworth C500 PDF brochure. One picture shows a truck with a opened hood and shows really nice how a part of the fenders is attached to the cabin. So this part of the fenders stays in place when the bonnet is opened, I really love this concept.
With the hood opened one can clearly see the inline 6 cylinder engine with a displacement of 906 cu. in. (14.9 L). The horsepower range is from 455 up to 505 HP and this engine has a torque range from 1550 to 1750. Just some details that do not influence the performances of this truck model.




Improved battery box accessibility
One other major improvement is the battery box accessibility as well as the location of the on/off switch. To make this achievable for as many builders as possible I sticked to the battery box with 6x AA batteries, LEGO® Power Functions® Battery Box with Orange switch item number 59510c01. Building US Truck T2 I was more limited with solutions then I am now. With the original US Truck T2 to replace the batteries the entire roof had to be removed together with the sleepers back side. For the on/off switch I installed a complex mechanism that needed small doors to operate the switch. As complex as it sounds it really was and I was never happy with this solution. Building US Truck T5, the custom Peterbilt 379 UltraCab I did in 2012, made me finally come up with a much better solution. The roof on that specific truck had a hatch to access the battery box. Never figured out why I didn't come up with this initially because my first system was so complex and uncomfortable. Anyways now it is implemented in US Truck T2 MkII too.




Final improvements
One of the noticeable improvement is the windshields window frame. First build used Bar 4L item number 30374. Besides decorative purposes these bars are supposed to support the roof, which they didn't! Thanks to digitalizing my model with BrickSmith I noticed/discovered a much better solution. Besides that it looks less fragile this new window frame really became supportive. So now the roof is supported at either end, back and front.
When TLC released LEGO® Power Functions® IR Speed Remote Control Unit item number 64227 I was really excited about it. First build also used a XL Motor to drive but with the use of Power Functions Remote Control Unit item #58122c01 one has to be very careful. Because of the enormous strength of the XL Motor the drive line could be damaged easily. For this very reason I had to gear down the drive line quite a lot. US Truck T2 MkII has less gear reduction and is therefore quite a bid faster then its predecessor.




Building instructions
To give you an idea how the instructions look like here is a preview. Creating these instructions both quick progress on your build as well as each step being easy to understand the same time were very important. Early in the building process you will see what is happening, what it is that you are building. You will be very excited from the moment you start this build till you finish the build of US Truck T2 MkII with a total number of parts of about 1800 pieces.
To achieve this a lot of floating items are used, with added arrows to show where these items are suppose to be. Together with a lot of so called call outs (the smaller windows within a step that shows the assembling of a smaller sub part of the build) together with multi part steps the build will be in a flow.
Check mocplans for the instructions and rebrickable for the parts list!

My MOC 'Fleet' contains all of Han Crielaard's trucks as well as a few of my own. I'm currently working with Han on his new Stone Trailer Truck. A couple of my Trucks are at the bottom of the Stone Trailer page. I enjoy building trucks that look like the real thing! (As yours do) When new instructions are released, I'll be building again!! Thanks so much.....AFOL

Quoting Stephen Wilson Beautiful Truck, lucky to have one in my fleet. Looking forward to matching this to your new trailer MOC. The two together deserve a glass case!
Great to read this comment as well, what does your fleet look like? Like I wrote in my reply to your comment with the trailer: You are so welcome! And about the glass case, that is about the nicest thing to hear about my MOCs…!!!!

Quoting Stephen Wilson I recently purchased these plans, and am gathering all parts. Any chance you could produce plans for your Drop Deck Trailer? I'm excited to build with plates and bricks, haven't built this way for years, thank-you for letting the AFOLs and other folks build your Master Pieces!
Great to see that you purchased these plans, and have much fun building this one! Yes I will do instructions no how to build that trailer you are talking about! I am working on those as we "speak"!!! Want you to know that this trailer will also be improved in so many ways as I did with the truck you mentioned...!!! Thanks that you like my models MOCs so much and no thanks for sharing, it is an honor!!! :-)

Thanks to start with!!! You are right, it is a little steep I realize this myself too. Also are you right about kind of deserving this, even though this model seems quite small, it really is complicated. Building it will convince people... ;-)

Quoting Matt Bace These are some really nice updates to a MOC that was absolutely superb to begin with. It's great how your MOCs evolve and improve with time.
That is very nice of you! In a way a MOC is never finished. As long as I develop my building skills a model can always be improved. Since this MOC was so popular I thought it would be nice to make instructions. Because of this process rebuilding and improving was obvious...

Quoting Max The Owl This is truly amazing. There is no other way to describe this work of art. I have seen some pretty good Lego trucks out there, but all your creations are on a completely different level. Do you have any plans to remake the "US Truck 3"? That has always been my favorite of your creations, and if I may say so, the most interesting as well.
Well that is so nice of you, refer to it as art, thanks!!! Yes I surly do have plans on rebuilding US Truck T3 as well. To be honest I do have a lot of plans, so please be patient. US Truck T3 is the most interesting you are right about that! That is also the reason it will be the most challenging to create instructions for. So many features and stuff, but I'll give it a shot one day for sure!!! Thanks for asking... :-)

Yeah I know it was about time to create building instructions...you are right about it!!! :-) Never managed to find the time to do so, but I finally did and it was worth all the effort I had to put in. Please do not underestimate this, it really is time consuming!!!

Quoting Nathanael Kuipers I had the privilege to see a preview of the instructions on MOCplans, and can say that they are of great quality. Furthermore it's remarkable that the whole model went through a complete redesign, but still looks pretty much the same. It just shows how much extra effort was put into this whole project by improving everything. Now that's dedication!
Thank you so much Nathanael!!! This is very much appreciated especially because you recognize the effort that is put in. A lot of people might underestimate this, you don't... :-) Great that you had a preview on MOCplans and thanks for the compliment!
