The "u" shaped piece is still attached to the bearing inner race.
The bearing outer race is still attached to the control sheave.
The ball bearings are ???????
Hard to tell if there is enough meat left to use the control sheave after removing the bearing outer race.
Removing the "u" shaped piece is questionable.
So 'best' solution is to acquire a 'working' MVII control sheave(not often found).
IIRC the M5/MV control sheave can be machined to match a MVII control sheave(the hub is shorter).
Coming up with a bearing with "u" shaped piece still attached is very unlikely. That will require some machining expertise.
Wish I had better 'news'.
