As the spur use itself with time, I thought that I had to move the pinion closer to the spur, but with this method I used my pinions pretty quickly... So now I decide to stick with the original shimming when the spur was new, and it seems to work, my pinions and spur dont use themselves anymore. At least for the moment...
