Interesting question about track pulling to one side or the other. We had this problem on a Tank and even went as far as swapping tracks over from one side to the other, and even marking the final drive to make sure there was not a different ratio. Turned out that one side had an extra link, even though I am pretty sure we set both tracks up with the lineal length the same on both sides. Once we had taken the link out, we also "quartered" the track as well to achieve the correct lineal lengths. Tracks worked perfect after this.
We also run a M113, which has 64 links on one side and 63 on the other, and this is factory setup. Not entirely sure why they did this, whether it was for road camber? , but it is a bastard driving down our roads and it pulls to the left, but we drive on the left hand side, so is it the camber doing this? if I was in the good old US of A, where they were made , I would be on the other side of the road and it would be driving straight?Cheers Andrew.
