Cummins Service Kits & Overhaul Parts

Cummins Parts Inquiry Checklist

For Cummins parts, the model, CPL, and engine serial number help confirm the correct option. Include the part number, quantity, and whether the order is for routine maintenance, urgent repair, or overhaul planning.

Parts We Commonly Quote

• Filters, belts, seals, gaskets, and maintenance kits
• Fuel injection, cooling, lubrication, and turbocharger parts
• Sensors, control components, and replacement assemblies
• Overhaul components for engines in generator and industrial service

Send CPL and Serial Number

Cummins CPL and serial data reduce the risk of wrong replacements, especially when several versions exist for the same engine model.

Where to Find the Numbers

The engine dataplate is usually on the gear housing or the rocker cover. It shows the engine serial number (ESN), the model, and the Control Parts List (CPL) number. The CPL defines the specific build of that engine, so two engines with the same model name, for example two QSK19 or two KTA38 units, can need different injectors, turbochargers, or fuel-pump references if their CPLs differ. A clear photo of the dataplate is the quickest way to avoid an incorrect part.

Service Kits Versus Overhaul Kits

• Service kits cover scheduled items: oil, fuel, and coolant filters, belts, and the gaskets disturbed during routine work
• Top-end kits add head gaskets, valve-stem seals, and the seals needed for cylinder-head removal
• In-frame overhaul kits include pistons, liners, rings, rod and main bearings, and a full gasket set
• Out-of-frame overhaul may also need crankshaft, camshaft, and oil-pump components depending on inspection results

Tell us which level of work is planned and we will quote the matching kit per engine, or list the parts individually if you prefer to build the kit yourself. More Cummins coverage is on the Cummins parts and Cummins engine parts sourcing pages.
