You mean your pinion wore like that against plastic spur?
Somethings fishy with those pinions, IMO - a decent hardened pinion does not do that even with metal spur.
Are you sure that your pinion was allright before you put it on place?
The teeth seem deformed and are/seem too thick at the right side (don't fit the spur), hence the noise & wear at spur.
Well didnt notice anything wrong when it came out of the package, that one there is the 16t and I bought a 15t so when I took it out last night I looked it over and its fine, odd thing is its narrower then the 16t was but as you can hear its making the noise to.
