The overrunning alternator pulley on your car is mounted on the alternator drive shaft. Without an overrunning alternator pulley between the crankshaft and alternator, the irregular rotation speed of the crankshaft will cause your drive belt to become tensioned and loose intermittently. This causes significant wear on the drive belt and also generates a lot of noise. Additionally, the overrunning alternator pulley reduces fuel consumption and allows for smoother driving.
If you need to remove the overrunning alternator pulley, it's important to use the correct tool. A special combination spanner for the overrunning alternator pulley allows easy access and prevents the pulley from rotating when tightening or loosening the nut. If you don't know which size is suitable, or if you frequently work on different cars, you can opt for an overrunning alternator pulley toolset. These sets contain combination spanners and sockets in various sizes, increasing the chances of finding the right fit.
