Genuine Cummins piston cooling nozzle for the QSK50 diesel engine, part number 4099041. The piston cooling nozzle sprays engine oil up under the crown of the piston to carry heat away from it. A blocked or bent nozzle lets the piston overheat, so the nozzles are checked whenever the pistons are out.
Condition: new surplus, meaning a genuine part bought for a project or a fleet that has not been run in operational service. 8 units available; price on request.
