Our stock list gives this number for the QSK60 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 water pump kit for the QSK60 diesel engine, part number 5633398. The water pump circulates coolant through the engine, and this kit number covers the pump as Cummins supplies it. Our stock list does not say which cooling circuit it serves: the CM500 build CPL 2848 has a two-pump, two-loop cooling system, with one pump on the engine jacket water circuit and one on the low-temperature aftercooler (LTA) circuit. Send the number on your pump and your ESN and we confirm that it is the one you need.
5633398 supersedes 4376121: 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 QSK60 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. 1 unit available at £1,200 plus VAT.
