Hello
I am rebuilding a 60hp gearbox with the early donut syncro assembly with hub and sleeve. The pictures attached shows the old syncro (1) and the new (2) that I will put in my gearbox. The sleeve is not symmetrical, the one side of the fork groove is wider than the other. The hub goes in both ways.
The new syncro (picture 2) have the hub the other way compared to my old.
Does anyone know how it should be?
