I upgraded my NV4500 with a Southbend clutch a couple years ago, and still have the old flywheel and clutch sitting in boxes on my shop floor. Is there any value in trying to sell these as used or should I just take them to the recycling center?

 

I would say the flywheel is worth something to the right guy.
A used clutch depending in what shape it is may not be worth much.

I keep those spare parts when I install South Bend clutches in my trucks.
