I will try to wrestle the digital camera from my son when he returns home and take a picture of the undercarriage of my dozer. I probably won't get it done tonight, He is at a girls house and most likely won't be home before dark.
For a small dozer such as you are trying to build the undercarriage on mine is pretty substantial with several bogey wheels and top rollers. I don't know if this will help you but I will post it when I can.
