Our stock list gives this number for the QSK50 without naming the build, so confirm it by your engine serial number. Fitment and interchange data is compiled from manufacturer catalogues and cross-reference listings and can change at engine serial-number breaks. Quote your engine serial number and existing part number when you call and we will confirm before dispatch.
Genuine Cummins push rod for the QSK50 diesel engine, part number 3057139. The push rod carries the lift from the cam follower up to the rocker lever, which opens the valves. A bent push rod upsets the valve timing and lash, so it is replaced rather than straightened.
3057139 supersedes 205492: Cummins replaced the older number with this one, so this is the part to ask for when your parts book or your old part carries the older number. Our stock list gives this number for the QSK50 but not the build it fits, so send your engine serial number (ESN) and the number on your old part and we confirm the match.
Condition: new surplus, meaning a genuine part bought for a project or a fleet that has not been run in operational service. 32 units available at £120 each plus VAT. 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.
