Scroll Wheel Bearing (V1) for Apple iPod Classic 1st Gen M8541 5gb 10gb. This part only fits the 1st generation iPod Classic (the one with the scroll wheel that actually spins).

I call this style "V1". It has 9 balls in the bearing. Make sure to count yours before ordering. 

This is a genuine part pulled from a used iPod. It has been cleaned/tested and is fully functional.
