Honda S2000 F20C AP1 Idler bearing

This is the bearing that sits in the middle of the Aux Belt (Alterator Belt) Idler Pulley. It can also be used on the Aux belt tensioner pulley.

Typical symptoms of a worn bearing is noise on idle coming from the idler pulley.

Simply push out the old bearing from the Idler pulley, and press in the new bearing. The pulley itself does not require replacement, it is only the bearing that wears down and becomes noisy !
