Well I'm going to try my hand at tearing down my NH 1715 and put in a new clutch. This is all new to me but I've got my camera to take pictures along the way. I'm way interested in using an aftermarket clutch kit over the NH for money reasons (thats also why I'm going to tackle this myself). Anyway I'd be real interested in hearing from anyone on their experience with aftermarket clutches. I've seen them for anywhere from $132 to $400 for the kit. Same components in the kit. Why the big difference in price? Any opinions? Also would be interested in any other work to include while my tractor is split. Thanks in advance.
