I had about 50 sets of C.R. gears made for the TR-6 The following may be
of help
to some of you TR-6 folks:
teeth counter gear teeth mainshaft gear ratio
diameters
1st. 19 30
1.88 2 7/16 x 3 3/4
2nd. 26 31
1.42 2 13/16 x 3 5/16
3rd 28 29
1.24 3 1/16 x 3 1/8
4th 31 26
1.0
These are all stock syncro gear sets using the stock replacment parts
and
bearings.
