Beomaster 6000 Quad: Tuning Wheel Pulley Damage

Today I removed the bearing that (normally) holds the pulley that is driven by the tuning wheel to have a more diagnostic look. After removing the three screws that hold it to the bottom of the enclosure, it came out. Here are some pics:





















And from the bottom:

While it appears that the pulley bottom-end may have been press-fit into the bearing, this cannot be since the pulley groove would be much lower than the the string level in that case. This suggests there is a part missing in between the bearing and the pulley. Not sure at this point what to do about it.
