Don't even think about re-using a bearing you have pulled off using a
puller- unless you can grab the inner race, not the outer. Grabbing the
outer race with any force brinells the race, guaranteeing later failure.
These bearings are typically 5 bucks or less. false economy to try to
Mind the clearance on the plastic insulator (on the end bearing) that
was loose. It has to take up the space, and needs replacing if worn,
except at times the case wears, so be"wear" of that...
but it is an insulator, so don't fudge it together with shims and stuff
if it may not still function as one. (an insulator that is)

Or is it to a single diode?
