If you have a stock A-series motor and need to replace this type of vibration damper, a rebuilt front pulley will often do the trick. Single v-belt pulley type only. It can also be used as a replacement for the two-piece Cooper 'S' unit on street motors. If you intend to replace an early stamped metal front pulley as found on 850 Minis, you will need different front brackets to allow the larger size of this pulley to fit; please contact us before ordering. Thickness: 1.2" front to back. Ref: CAM4929R, CAM4929-REB, SEVUCAM4929, CAM4929.
For original Cooper S front pulley, see AEG0454 and 12A0367 damper ring.
