China OEM Timing Belt Idler Products - removing alternator pulley F-239808 – RNA

1. It has one-way slip performance, and its basic principle is similar to the one-way clutch gear on the starter

2. It can be divided into outer ring and inner ring. If the inner ring speed (i.e. rotor speed) exceeds the outer ring speed during operation, the pulley will slip immediately, and the inner ring and outer ring will be separated.

3. There is a plastic cover on the port to prevent dust from entering the interior, commonly known as dust cover.

4. Rotate directly on the rotor shaft by relying on the thread on the back. Therefore, there is no hexagon nut on the outer end face of the pulley. 5.
