Description Reviews MINI Harmonic Balancer / Vibration Damper / Crank Pulley - This harmonic balancer made by Corteco fits the B46 and B48 engines typically found third generation S model vehicles. When the rubber dampening comes apart and fails over time, a vibration can be felt along with rotational noise. This pulley can come apart and also destroy your drive belt, which in turn will leave you stranded. This crank pulley is a direct stock replacement for a failed harmonic balancer. Bolts included. Please view all photos to see what a faulty pulley looks like and how it will rub against your engine case when it fails.
