during the last rebuild i noticed the ring of the thrust bearing was a bit deformed but since i did not notice any performance issue i used it again.
now in this time's rebuild i found this!
and I still was not noticing any issues with my lutch ... the clutch bell spun freely and smoothly... in any case i changed it now! difficult to realign all the pieces

This original thrust bearing with copper(or brass) ring lasted me since february this year!! and it was still doing fine, if i had left it alone
now i'm using the one with carbide ring...
