Split it for a rear main seal and to rebuild PTO clutch. It didn't release good prior to the split. Didn't get any worse, didn't get any better. Since it was a metalic clutch with very little wear and still questionable future as to if I would keep it I didn't put a main clutch in it. It has been torn all to pieces fixing hydraulic issues from years of neglect and old/hard o rings.

Pilot bearing is new. Never been a loader tractor. Flywheel didn"t show much wear or indication of high heat.

Those button clutches will warp unlike regular disks the buttons sort of twist.
Also they wear the pressure plate and flywheel faster than they wear themselves. Sometimes this causes them to drag around the edges of that worn down area.
I seldom reinstall metallic disks especially on loader tractors where you do a lot of clutching.
They are meant to engage positively on jobs such as plowing etc. and easing them in and out is like setting a grinder up to your flywheel and pr. plate.
There are also kevlar disks available but I doubt you will need that.
