Ford 861 clutch pics old vs new question

Hi all,

A while back I asked about a new 2-stage 5-speed clutch kit I got for my Ford 861. I noticed the clutch disc has dampening springs on it, while the new one didn't appear to. Showcrop asked for pics so here are a few of the old and the new clutch. Is it a bad idea to be without those springs, or am I worrying for nothing. Or is this just a different design accomplishing the same thing? Another thought: maybe there are dampeners on the new disc that are just not visible from this side of the disc (and could the old disc be installed backwards?).
If it would be worth doing, I would consider getting just the disc from New Holland (assuming it has the springs) and replace the disc on the new clutch pack that doesn't have the springs. If that is an involved procedure requiring adjustments, etc. with special tools, then I would might skip it. Any thoughts appreciated.

Thanks!

Thank you Bern.

I would use the tractor hard periodically. Maybe it would be more important if I were running a baler.
It would be nice to have to help reduce vibration or wear in the gearbox, but I guess the makers of the clutch kit saved a few bucks by using a disc without the dampeners. Wish I knew more about this in advance. Learned something! Thanks

Damper springs are meant to smooth out torsional engine vibrations. While they do a pretty good job in accomplishing this task, they can and do fail after high hours of use, as the springs usually end up beating out the pockets where the springs ride. Once that happens, they fall out and jam up the clutch to the point where it won't release.

Unless you're using this tractor hard all day every day, I wouldn't worry too much about the lack of torsional vibration reduction. It's nice to have, but not an absolute necessity.
