Changed the rear tire yesterday and greased the splines on rear of drive-shaft on 2013 Guzzi Stone.
Put it all back together, but now realize from studying the parts diagram that I reversed the order of the spring (GU94321099) and the plate. Looks like the plate fits in front of the circlip on the coupling, then the spring fits between the plate and a hole at end of drive shaft.
Sigh. I'll take it apart and do it right. But does anyone know what exactly is the function of this spring? Yes, I know, it pushes backwards...but why do we want that?
