Genuine Cummins viscous vibration damper for the QSK50 diesel engine, part number 3628650. The viscous vibration damper is fitted to the front of the crankshaft and absorbs torsional vibration, the twisting of the crankshaft as each cylinder fires, which would otherwise fatigue and crack it over time. A damper that has leaked its fluid, been dented or run hot no longer works and is replaced.
3628650 supersedes 3626722 and 3032732: Cummins replaced the older numbers with this one, so this is the part to ask for when your parts book or your old part carries one of them. Sources do not say whether an engine takes one or both: confirm by ESN.
Condition: new surplus, meaning a genuine part bought for a project or a fleet that has not been run in operational service. 1 unit available; price on request. Please confirm the part number against your engine serial number before ordering. In UK stock — call +44 7951 632187 or message on WhatsApp for shipping and availability.
