Freewheel alternator pulley (OAP or OAD) upgrade

While usually reliable, I have replaced a few of these as an Audi tech over the years. Common failure is it seizes and no longer freewheels. Yoi can hold the fan inside the alternator and chwck if the pulley freewheels in both directions. There is a special socket for the bolt to mount it but I don't have a picture right now. For the most part, a reliable part.

I assume you can change the pulley incar, but that was no option for me, since I'm currently replacing all the seals of the engine.
