Friction wheel problem from last year still an issue

I have a Craftsman 5-23 with treads instead of wheels.
I had replaced the old friction wheel because it had a large crack that caused it to stop moving when the crack was facing the drive disc.

The issue is that the new friction wheel leaves a rubber residue on the drive plate after running 10 minutes or so.

This residue becomes sticky and when I let go of the lever to stop the machine, it keeps going as if I'm still holding the lever to go.

Moving the lever does nothing so I have to bounce and yank the machine to get the friction wheel to let go and stop.

I tried scraping the residue off and dusting it with graphite but then it just slips and goes nowhere for a while.
Then it begins to get traction and works for about 15 to 20 minutes before the friction wheel starts to stick again to the newly applied residue.

I know new motorcycle tires have cosmoline on them are like riding on oiled glass until it is cleaned off.

Was there something I failed to clean off the wheel or some other prep I needed to do?

The friction wheel surface is wearing off and sticking to the drive plate and I don't know what to do.

try cleaning both the drive disk and the friction disk with alcohol and a clean cloth to remove any oily residues and see if that makes a difference. You don't want to add anything like graphite. A clean, dry set of disks should provide all the friction you need. Pay close attention to any other areas that may "oiling" your disks during operation. MH

Make Sure all the Drive Chains are lubed and are not binding.

Also make sure you have it adjusted properly. and make sure the return spring is hooked up correctly.

Both the drive, and driven discs should be square with each other. There is the possibility that the spring pressure is too great, causing scrubbing of the rubber. Or just some stray oil, or grease gets on it as was already posted.
Happy new year.

I'll vote for making sure it's adjusted to not mash them together too hard as well.

Was this an aftermarket friction disc > Some rubber compounds react with aluminum and get soft and sticky. Clean the rubber and plate with alcohol (Isopropyl) and try again. If that doesn't work maybe get a friction disc OEM from a dealer at least they are not expensive.
