Oh, that is good news!The good news- I DID break the PTO clutch free via the driveshaft under the footrest/against the frame method.
If you use it a bit, cycled the PTO on and off, esp with some kind of load on it, and leave it in the off position when not in use, you should be good to go long term.
Sorry about the milkshake, but you're doing the right thing. Esp run it a while to heat it up, then drain. That will help get the water out of there.
If you get the idler off, you may discover that you can just change out the bearing.
