Cummins KTA38 Engine Parts Guide
A sourcing reference for Cummins KTA38 parts — the 37.8-litre V12 used in mining, drilling and power generation — with the high-wear spares we stock and how to quote quickly by part number.
About the Cummins KTA38
The Cummins KTA38 belongs to the K38 family: a 37.8-litre, 12-cylinder V engine, turbocharged and aftercooled (the "KTA" prefix). It sits just below the KTA50 in the K-series line-up and shares much of its design philosophy and many service practices. Typical applications include mining equipment, drilling rigs, and prime/standby generator sets. As with the KTA50, its high-duty operating profile means operators reorder the same wear parts on a regular cadence.
Common KTA38 wear and overhaul parts
The KTA38 parts we quote most often:
- Injectors, injector cups and sleeves
- PT-type fuel pumps and fuel lines
- Piston kits, liners, rings and bearing sets
- Cylinder heads, head gaskets and seal kits
- Turbochargers and turbo rebuild kits
- Water pumps, oil coolers and thermostats
- Full filter and gasket/seal overhaul kits
Ordering KTA38 parts by number
Send us the Cummins part numbers if you have them, or the engine serial number and application if you do not. We cross-reference against the correct build so the pistons, liners, bearings and gaskets all match your specific KTA38 revision — this matters because K-series engines received running changes over their production life.
