[Fot] Crown and pinion gear break in

[tr4racing at googlemail.com]

Maybe something to know about Diffs:

 

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

 

1.	Gleason gears
2.	Oerlikon gears

 

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.

 

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

 

Cheers

Chris
