lego-technic-motorized-bulldozer-part3-step-74Welcome 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.

lego-technic-motorized-bulldozer-part3-step-75Manual 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.

lego-technic-motorized-bulldozer-part3-step-75-9Next 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.

lego-technic-motorized-bulldozer-part3-step-75-15Joining 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.

lego-technic-motorized-bulldozer-part3-step-76-13I 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
