I am in desperate need of the variable speed sheave for a 70's John deere 170. I am needing inside sheave, closest to the gearbox. I know these were used in mustangs and case skid steers as well. D57831 is the original part number. I have searched the internet and salvage yards for hours with no luck. If anyone could point me in another direction I would be grateful.I would imagine this gearbox was used in other applications as well.

I wonder how similar that one is to the Bobcat 600 one...

I may have access to one from a bobcat 600.

Thanks for the reply, I am pretty sure they are the same design but will not interchange ( i will research some more). The bobcat is a lot better design, mine uses a set of plastic key ways to keep the two sheaves together.
