I fixed mine my cleaning off the goo and sliding a
thick piece of surgical tubing over the pinch roller.
I had to strech the tubing quite a bit, but it works
just fine. I have heard other people use o-rings but I
don't know they keep them on.
I use O-rings to rebuild the 9810 card reader roller, but I turn a new
hub from brass rod with a groove to take the O-ring....
Making a complete new metal hub for the tape drive would be a lot harder,
due to the tachometer disk at the bottom end (I am not sure how easy it
would be to move this to the new metal hub).
