Cassette Take-up reel fails to

I’ve had this Sony since early 90s. I finally decided to fix it. I took it apart, cleaned everything, replaced the disintegrated belt and reconnected.

FF works, RW works. When I press play I can hear the recording, but the tape spills out after it runs through the capstan and pinch roller. The take-up spool/reel/spindle does not move.

I’ve checked the tire wheel which is supposed to drive the take-up spool with friction and it slips. So I cleaned the tire wheel rubber and dried it, which seemed to improve it as I turned the capstan manually. But as soon as I add power the take-up spool hardly moves and the tape spews out.

I cant see how to improve it - it can’t be the drive belt as it’s new. The spring which pushes the tire wheel against the take-up spool works well - Is there a drive that I cannot see under the take-up spool? Or should I replace the rubber on the tire roller? If so, where do I get that from?! Any help appreciated.
