Making a new aft chassis for the dozer. I already had the larger spur and smaller pinion sets so since Tom thought I was too fast (he always seems to be right about this stuff!) I decided to do a little refit. I'm just guessing at the ratios. It ought to be close, and even if it comes out too slow, that would be good anyway! Then I can order a couple new motors geared a bit faster with a lower stall value to protect everything.
With any luck this will all turn out perfect, have great performance and I'll have it running by 2pm today!
Oh, and thinking out loud here, I realize that without seeing this thing up close it will be hard to picture, but..
I need to figure out how to add a bit of tension to the tracks now. The pins cast on the links are starting to wear a bit and they are just a bit too loose now. Don't want them to get tight, but they are too loose they way they are now. The spring at the front idler wheel is not looking like a good solution.
