Timing Belt Drive Pulley – B-Series (Toothed, CKP Sensor)

Timing Belt Drive Pulley – B-Series (Toothed, CKP Sensor)

The 13621-P72-A01 is the OEM toothed timing belt drive pulley used on Honda B-Series DOHC VTEC engines. Mounted on the crankshaft, it not only drives the timing belt but also provides the timing teeth required for the crank angle sensor (CKP) to read engine position. Over time, worn or damaged teeth can lead to belt tracking issues or sensor misreads. Replacing the pulley with a genuine OEM part ensures accurate timing, proper belt alignment, and reliable sensor feedback for both restoration and performance builds.
