Updated S85 helical crank hub gear.
Update your early model (up to 12/05) M5 or M6 vanos pump gears with this later version when rebuilding your vanos oil pump. The updated gear has a redesigned tooth profile to address failures in the early versions.
Note: You will also need the updated Vanos pump helical gear with this item if converting from the older version.
It's also recommended to update the pump chain guides as well.
