Is that legal up there in WA? Around here it's a big no-no. Maybe the grounding rod gives you some protection but I still think you could end up with size-able currents running in the ground lead.
They make taper lock hubs for this kind of thing. The piece with the outside taper as a split down the length of it. That part goes on the shaft. The piece with the taper on the inside mounts to the pulley and slides over the other piece on the shaft. Bolts around the periphery pull the two pieces together and squeeze the shaft piece tight on the shaft.
I know about this because I used one on the electric car I built. Believe me, once it's on there you're not getting it off again. MUCH better than a Woodruff key.
Looks good Phil. Maybe a stack of appropriatly sized washers welded/bolted to the dollies would make a little “post” for the ROPS to center over.
Just a note for clarification, my dozer (2002?) doesn't have a sight gauge on the left reservoir. Wish it did.
WOW! You have been doing a LOT of work. I agree that overhead crane looks like it's indispensable.
Kinda scary seeing it all taken apart like that….and the worst is yet to come!
Good job and thanks for keeping us posted. Personally I'm looking forward to seeing what the final drives look like.
Looking at the two pictures in this thread, I stand corrected. the bands look quite similar in thickness.
the extra flexibility must come completely from the segmented pads. I really would like to get my hands on a set. Of course I'd like to get my hands on a dozer but that's another thread. 
I second the idea of using something smooth, thin and strong rather than a strap. If a strap gets caught on something you're in a world of hurt.
Blaze the trail Phil!
I don't see a big problem with yanking out the old bands. (with the caveat that once you've started you're committed!) It's putting un-segmented bands in that I was worried about. The older versions have a thicker metal backing. My concern was that you would have to straighten them so much to get them in that they will deform past their plastic limit. This would then put a kink in the band and that's bad.
The new bands are thinner and more flexible. the segmentation will also let them bend easier.
I say, if you are prepared to go all the way (removing the finals) then there is no downside to having at it! The cost/benifit analysis is pretty clear.
I amend that last statement a little. There is one small downside and that is you don't get to inspect your clutches by avoiding the full job. It sounds like you are a person that's not going to avoid work if it has to be done though.
Good luck and post pictures.
I would bet half the sponsors of this site would have that. I looked quickly at Discount Tractor and they seem to carry Foton parts. CircleG, RanchHand, etc. Just go to the dealers section on this site and start calling.
