Dean,
 I have been using the new Moss provided heavy duty synchros in nearly all
the gearboxes I rebuild now.  They grip very well, are round and appear to
be as close to the original Triumph part than anything else I have seen.
Pricy, but worth it in my opinion!

   Has anybody found a supplier of good Synchro rings for the TR2 -6
gearbox. I have pulled apart a gearbox that I rebuilt in 1996 and the
Synchro rings are shot on 2nd and 3rd gear.
Everything else is in great shape and does not need replacing.
The layshaft hardly has any kind of mark where the bearings ride. This is a
street TR6 box which usually wears out the end with first gear. 

      The synchro rings on the otherhand will not work on 2nd and 3rd.
No braking action left. I know where I bought these and stopped using them
many years ago. I find that many of the one's supplied now don't work well
when the box heats up. I think they must expand when they heat up. This box
was also run with Redline MTL in it and it is spotless inside. Bearings are
smooth and layshaft washers show no marks or wear. It is a late J OD box
with steel bushings in the main gears and nothing needs replacing. I would
not be working on it if the Synchro rings had been any good.

       Any body no of any good Synchro rings?

Dean T.
