Scott,

Here is a picture of one of the drive cog wheels on the dozer. Did you simply bevel the inside surface, starting at the cup and making it pointed toward the points. Sort of trying to get the cogs to slice or cut the dirt when it comes into the driver? Also, do I want the cup to be more narrow so that there is not so much surface to trap something in the cup between it and the tread?



I had a thought, don't know how well it would work out. What about putting little pieces of low density foam into each square hole of the track chain so debris can not get in?

Jim, see where the dirt gets compacted between the teeth there, i am calling that a "pocket" and what i do is make that pocket a steep ramp down away from the the side that faces out. So, looking at the drive wheel from the outside you would not see that it has been modified but, if you looked from the backside you would see that the pocket has been sharpen like a serrated knife. Being just soft pot metal though, i would not make the edge too sharp or the drive wheel might wear out very quickly.

Hopefully if you look closely to this photo you can see how i cut a steep ramp into the pocket and just a sharp edge actually touches the drive chain.
