Welcome to the third and final part of the Technic Scotland build of the Lego Technic Bulldozer.

Manual 3 takes adds the front blade and rear ripper to the model, adding that extra realism.

Manual 3 is the slimmest of the manuals taking up only 37 pages (Manual 1 – 61, Manual 2 – 61).  This bit was one of the easiest parts of the build and also the most enjoyable.  After 20 mins I’d built something substantial.  The other sections you’d spend 2 hours building something and it would be reasonably small.

The front blade

The first part of manual 3 builds out the mounting for the front blade.  Nothing too difficult to build, although I did make a major mistake.  I mounted the blade riser bits on the wrong way around.  I only noticed when the blade wouldn’t raise correctly.

Next the front blade.  Again nothing strenuous, big pieces, making up a big section.  The front blade is made up of 3 major bits – the bottom section, the main back piece and the top.  The back is made up of 3 square sections held together with black rivets.  On to that a few layers of plates are added making up the back.  The base is simply 2 layers of plates, as is the top section.

Joining the blade to the rest of the model was straight forward.

The rear ripper

On to the rear ripper.  I’ve still not worked out how it works; I just know it seems to work.

I then found out a major issue – one of the crucial parts was missing!  A small part, probably a few grams was missing – no sign of it.  Unfortunately this temporarily stopped the build until I could find a replacement part.

I eventually located a replacement part and continued with the build. 

The last part is to join the rear ripper on to the base model.  This requires very nimble fingers!  After a couple minutes it eventually went together.  A major tip would be to connect up the universal joint first, and everything else will line up.

Model finished. 

Time taken for 3rd part of the build – 20 minutes

Welcome to the second part of the Technic Scotland build of the Lego Technic Bulldozer.

Manual 2 takes the model from the basic chassis to a functioning model – minus the front blade and the rear ripper.

Thankfully this manual didn’t seem so technical and only a few mistakes were made.  The first 26 pages deal with mainly body styling.  This seems to be a major change from Lego Technic models of a decade ago.  In the 1990’s Lego didn’t seem to bother too much about styling, but in the 21st centaury it seems they do. 

 

Throughout this section the right hand side of the model is built up.  There were a few steps where it was very difficult to tell exactly where a part should go.  In previous models a red arrow would show exactly where an axle would be threaded through.  In this model I sometimes had to jump forward a few steps to check.

On page 28 the two M size motors (set 8883) are added.  This is when it’s possible to see how the various gears fit together inside the model to actually make things work. 

Page 32 deals with the installation of the new Remote Control Modules (part 58123cx1).  Easy to install and connect up.  At the moment the  only other model to contain the Remote Control Receiver is the Lego Monster Dino (set 4958).

The next few pages build up the left hand side, in the same way as the right.

By Page 59 the base model is almost complete with the new style "Link Treads" (tracks) to add.  The new style tracks are a lot less fiddly to put together than the old smaller black tracks.  They’re also heavier making them much easier to handle.  I was suppressed though that were no spare track links.

Once the tracks were on that was the base model complete.  I couldn’t resist adding batteries to the controller and fired up the model for the first time. 

 As a guide to how large the model is, I compaired it by a standard 330ml can of Diet Irn-Bru (Scotland other national drink)

The Lego Technic Motorized Bulldozer was one of the bigger sets for 2008 with 1,384 parts.  As such it would have needed a large manual.  Instead Lego devided it in 3.

Pages 10 to 15

Manual 1 covers the main structure and runs to 60 pages - Lego have slightly cheated as the step number on page 61 is only 31 - after each main section  they restart at 1!

The build starts off by building the back half of the bulldozer.  The first 10 pages of the manual are the most difficult and complicated Lego I've ever build.  The first 19 steps takes 30 minutes!

Pages 15 to 18

Build Manual 1 runs as follows

• Front of the bull dozer containing one of the XL motors which will drive the left hand track
• Rear of the bull dozer containing one of the XL motors which will drive the right hand track
• Joining the two halfs together
• Building the 6 cylinder engine block
• Building the bottom rollers for the tracks

Pages 10 to 23

On models I've build in the past the item is normally semetrical length ways.  This is the first models I've build thats semetrical across the middle.  The motors to drive the tracks are not side by side - one is at each end of the model.

So far it's taken about 4 hours to build, and I lost track of how many mistakes I made.  3 Times I had to go back more than 5 steps to find where I'd gone wrong.

I bought the Lego Technic Motorized Bulldzer in August 2008 but it's taken me now to attempt the build.  My last build was the Lego Technic Mobile Crane and must admit I found it too complicated and I was making too many mistakes.  Finally I became fed up of it sitting in the cupboard so I decided to finally build it.

I bought the model via Amazon UK for £97.50, and it dually arrived in a few days.  Unfortunatly the box was very brused having been packaged in nothing more than a plastic bag.  No parts appear to be missing so fingers crossed.

The Box

For such a large box there's a large amount of "free" air inside it.  I'm not sure why Lego insist on using such large boxes other than pure marketing.  In this day and age of reducing packaging this seems something Lego should learn.  I bought the bulldozer online - the size of the box doesn't mater!

The box gives a good idea of the functions of the model - left and right tracks, raise and lower the blade, raise a lower the ripper.  The back of the box shows an alternative model - not exactly sure what it is yet though.

Included in the set is the new Lego Technic Power Functions remote control kit.  The remote control kit is made up of one controler, one battery box, 2 receivers, 2 XL motors and 2 M Motors.

Opening the cover on the box revelas a good idea of how each function work and how to use the remote control.

At this stage I'm still wondering how "remote" the control is - if it's infra red remote control (like a TV remote) it will mean you'll have to be able to see the model to control it.  If it's radio waves like a traditional remote control you won't have to be able to see the model.  I have visions of attaching a small wireless camera to the drivers seat and driving it round.

Box Opening

On opening the box I find 29 packets and 3 manuals.  There appears to be two sets of 6 packets - so these are either one set per side, or one set per end.  Of the manuals there doesn't appear to be one for the alternative model.

During previous builds of Lego Technic sets I've tried various methods of building -

• open all the bags in to one box,
• open the bags but keep the parts in the bags untill needed
• empty all the bags in to as many boxes as I can find.

For this model I tried to find as many small boxes as possibe - in this case an Ikea set of small drawers proved ideal.

Still to come
