I believe they had 4"x2" aluminum wheels (custom made) with nitrile roughtop on it.

Yes it is a single speed transmission.

Yeah, the first set is 32dp and the rest are 24dp
I don't recall the reduction but we didn't have any problems this year and we've been using the 32dp for quite a long time in our transmissions and never had any problems.

I can see if I have a picture off hand but if not then I can go take one but that might take a few days to get.

The whole is where our pot goes.

and the final drive shaft/gears were not in place yet along with the wheels at that point. I thought that the incomplete picture might make it easier for people to see how the direct drive actually works as the final hex drive shaft goes all the way through the center sprocket and center wheels thus driving the wheel and the two other wheels through the chains.

Yes, they're about 4x2 inch aluminum wheels, you can see them here without the tread. http://www.chiefdelphi.com/media/photos/30236
