Harmonic Balancer – MINI W11 1.6 Cooper S – R50, R52, R53 (11237525135)

This high-quality Teilex harmonic balancer is a direct replacement for Genuine Part Number Reference: 11237525135. Also known as a crankshaft pulley, vibration damper, torsional vibration damper (TVD) or crank pulley, it fits the supercharged W11 1.6 litre Tritec petrol engine used in the first-generation MINI Cooper S and John Cooper Works. This is the larger drive pulley that turns both the accessory belt and the supercharger belt, so a worn or separated balancer will show up as belt squeal, lost boost or erratic charging.
