C23625 and C23627 are both included an OUR UPGRADED parts in this kit. These adjustment nuts are for all "EZ Clutch" PTO's on Case Ingersoll Machines. They should be replaced as a set as they wear together and if not both replaced together it can accelertae wear on the new part. Our nut set are matched and CNC machined to our specs, they are black oxide coating to reduce friction and rust as they need to slide to functions. We also have releifs cut into the corners of the large nut for a couple reasons, One these are tight areas and where binding can happen, it also lets any rust or dust that may build up pass through and the small areas also the slight amount of grease used when you assemble to have a place to stay and lube as the nuts slide. These wont break or wear as fast as some OEM varients do.
