Thanks much for the help George (and to everybody else who mailed me
privately) Only question I have now is that the VB catalog pretty much
agrees with the above info except they've got it the other way round (the
1-1/2" used on the non-syncro box, and the 1" on the all-syncro). But
you're not the only one who has suggested it's the other way. Perhaps VB
just got it wrong?
Hopefully I'll soon have this engine all back together, though its tough
to work on in the winter cold, and with the Tr*umphs fighting for my
attention. Another question you, or any of the other bright MGers here,
might be able to answer for me. I noticed, by accident of course, that
fingernails can put very shallow, but discoloring, scratches in the new
conrod bearing shells. Time to get another set of bearing shells and be
more careful, or not significant enough to worry about?
