The TO bearing is lightly pressed onto the collar. The tabs on the back of the collar look to be worn a good bit where the clutch fork rides. I would check the collar and the fork to make sure they are not worn excessively. If they are, might be best to replace them. I usually wipe a little hi temp grease in this contact area during reassembly. Also, try to find a good TO bearing made in the USA. Some of the ones coming from off shore do not hold up very long, requiring early replacement.
