Love Dozer videos!

Jim, pads are original ones, I made new links, almost the exact same as original ones. On the first set I had the link pins slightly offset as to be closer to the sprocket. (Height wise) and on the new ones I have them centered. That was actually a flaw because I didn't catch that offset until I had already started cutting new ones. So I just ran with it. . But I don't think that makes much difference. The difference I made was to have slightly longer teeth on the sprocket and to have them more pointed. Plus on the geometry I tightened up the gap a little bit. If you look at a normal sprocket the gap is not exactly the size of the pin, but a little wider and get even wider as it gets towards top of tooth. On mine I lessened that gap. I think the combination of a sharper tooth ,(that will push dirt out instead of keep packing it in) and the tighter sprocket gap was key. I really should have relief holes in the track pads like 1:1 machines. That would also push out any dirt. But keep in mind the size of these things anything much bigger than sand grains is a problem. Also a long time ago titandigs gave some great advise on increasing the gap between the actual pads. Too tight of a gap will make the pads arch up if any little bit of dirt sticks inbetween them. I'll try and get some pics of the sprockets that may make it easier to see. Kind of hard to put into words, especially for me. What I'm thinking and what I'm conveying aren't always the same. Lol!!!
