I think I just died and went to scratch-builders heaven...
While searching for some reference pics to help with the tracks I came across this website:
komatsupartsbook.com
Not only did I find a detailed diagram of the Komatsu tracks, I found the full parts catalog that has broken down diagrams of every single part that makes up the whole dozer, right down to the last nut and bolt.
Not to mention every other piece of earthmoving equipment Komatsu make, which includes all the other Komatsu models available on the canon site.
