Nice model

There is a mistake with the track driving sprocket. This is the big "gear" that the tracks go over, and this is what drives the tracks. This sprocket should be aligned with the exact centerline of the track, as its teeth will then be able to engage with the PINS that are positioned inside the LINKS bolted to the tracks. As it is now, the sprocket is completely outside the links, and won't drive anything. There is also another problem in that the top part of the track is supposed to pass on top of the small roller, not "through" it. Actually, your roller should be much longer so it can support the total width of the links. If your tracks have too much slack, it's because you have drawn the tension adjustment fully compressed; it is the "gap" in the roller frame and in that gap there is a chromed cylinder that slides the front part of the roller frame in & out to take out the slack in the tracks. Secondly, I would like to know if this model is dimensionnally precise from official Caterpillar data, because I want to fabricate a large radio-controlled working model of this dozer. I therefore need accurate data and might be interested in your model if it is accurate. Lastly, as there is no bottom view, can you tell me if the frame is accurately represented underneath your model? Thanks!

awesome
