[TR] Calling anyone with transmission rebuilding experience - second attempt, part 1

[aribert neumann]

I tried to send this message yesterday but it has not appeared yet so I am
resending it - guessing that I may have had too many (or too large of)
images.   I'll splint it into two messages and reduce the image file sizes
- hopefully this message will go thru.

I'll start off with a quick comment - as I started to type the e-mail
address, up popped suggestions that started with TR.   Third on the list
was "TR3driver" - the late Randall (Young, I think).   I sincerely hope
someone will "fill his shoes" with respect to my questions.   I'm not on
any other Triumph related groups - you are all I've got for input.

I am in the process of reassembling (or trying to) my GT6 transmission -
please don't tune out, conceptually the trans is similar to the big
Triumphs.   On dismantling my trans, I observed that the split collars had
spun on the main shaft, wearing a relief in the collars and raising an edge
on the main shaft.  What keeps the collars from rotating when 1st gear is
in motion?  I am focused on preventing this problem in the future.  When I
rotate first gear on the shaft, the split washers rotate with the shaft.  I
am wondering if the tolerance stack up of the 2nd & 3rd gear bushings,
spacers, etc (from the circlip to the split collars) was too large allowing
first gear to push the split collars forward on the shaft.  What else could
cause this rotation/wear?

Images as follows - old mainshaft with raised edge from the spinning split
washers, good & worn split washers, good split washers nested in the first
gear pocket.    Off in digest mode preparing part 2 of this message.
