Reply to "Pinion Question"

thanks for your answers, the zf specialist also say : when the car have only 100 HP no problem.

But with 500 Hp it will fail. Its only a metter of time :-( BUT : Nobody have seen a broken pinion in a ZF ! I spoke to so much people and all what they say is : a ring and pinion never broke.
Some of them changed a ring and pinion set, when it looks like mine now. But nobody hade a broken one.
So I guess the first " layer" / sorry for my english , I hope you understand the meaning/ is a hard metal. Maybe it is normal that a pinion looks like this after maybe only 5 years ? I know the safty factor in Germany bac in the days was a least 1:2 so the ZF can take more than 900 NM for a while. So maybe those parts will live longer than you think ?
when it realy break, It will break in the 5 gear at full throttle and only the theeth from the pinion. I guess that there is no massive ZF chrash. The broken parts will fall to the side on the bottom from the zf. The Ring and pinion is "allone" in the zf. No other parts are in their way. Maybe it will fail one time , but without Booom and bang ?! :-)
