Maybe something to know about Diffs:

=20

On Triumphs, these days are two different types of gear available:

=20

1.      Gleason gears
2.      Oerlikon gears

=20

The workshop manual is referring to Gleason gear type. If you got an =
Oerlikon type of gear (the more modern one), and you try to set it up =
with the Workshop manual, then the gear will fail.

This is because, that the contact pattern, which is shown in the manual, =
is mirrored at an Oerlikon type.

=20

So most Oerlikons die of wrong contact pattern, with the pinion too deep =
in the Crown wheel, almost touching the carrier.

=20

Cheers

Chris
