The 28% Overdrive of the BN2 gearbox I sourced, has suffered the 'Shattered
Unidirectional Clutch syndrome'. As a result the steel ring in the annulus
has 3 hairline cracks where it is held in place by 3 'rivets'. It seems to me
that the rivets were creating a weak spot and were maybe ommitted later for
this reason. I sourced a replacement steel ring, without the grooves for the
rivets. I believe this later ring is a press fit, probably facilitated by
cooling the ring and heating the annulus. Is this correct?
The 3 28% planetary gears show some black discoloration and small pitting,
nothing major but just feel-able with fingernail. (The ring gear of the
annulus doesn't seem to have this issue) Do I replace these or should I not
bother too much with this? I can put pix online if this could help assessment.
If you have a spare/used set lying around let me know. Thanks for your help.

PS: I got the Peter Kumar letter as well but holding on to my project.
