My local dealer just called me and told me that Koyo doesn't produce any bearing with the code 83B569A... The only bearing that is produced right now is the one with the code 83B569AA... Also told me that the most likely scenario is that the 83B569A bearing probably has been replaced with the 83B569AA bearing...

Geezagillard can you measure the 83B569A bearing...? Inner dimension, outer and width... Just to compare them to see if this thing that my Koyo dealer said stands... Most likely it is true but it's better to be careful..
