[TR] Calling anyone with transmission rebuilding experience - 2nd attempt, part2

[aribert neumann]

Paul - thank you for your response.   I was in the process of trying to
stack the bushes, etc when I discovered the main shaft being oversize.
 Guessing RTFM refers to reading the manual?    The pertinent pages have
gotten quite stained from my greasy finger prints.

By clip I presume you are referring to the split collars - correct?   I did
not notice that there was a difference in the edges - maybe that was why
when I was checking the stack up of parts aft of the split collar the split
collars rotated as I turned first gear even though the stack up of parts
was in the tolerance range.   I need to go have a closer look at the
collars - I did not notice a difference in edges of the OD.  I do not
remember seeing any notation in the Bentleys about split collar
orientation.   I think you have answered my question about the cause of
the rotation of the split collars and prevented me from repeating the
problem!  Thank you!

For anyone else following along - the attached image is of first gear with
one (of the two) split collar placed in the pocket of the gear.  Since the
adjoining part facing this side of first gear is the shift hub (splined to
the main shaft, and the synchro keyed to the shift hub) the only way for
the collars to rotate relative to the shaft is if being driven by 1st gear.

In prep for stacking gears on the main shaft, you need to pre-install the
bushes to determine the required thickness of the circlip You se the
clearance by selecting the right thickness washer.  As stated all too often
you need to RTFM.   improper assy will be short lived. You'll be pulling
the tranny again MUCH sooner than expected as 2nd gear CRUNCH will not be
avoidable when the clip goes out again.
*You even need to pay attention to which side of the clip faces the
splines. The SQUARE edge needs to face the spline lips.The rounded one
leads to exactly what has destroyed your shaft as pictured*
