I just got around to ordering some longer 10t pinion gears. So, I will once again push this project off to the side until the gears come in. I also started taking the other side of the dozer apart so that side can be replaced also. My dozer is a little funny looking on the bench. A lot parts in a box and mostly just the chassis sitting there.
