KTA50 specifications and configuration checks
The Cummins KTA50 is a four-stroke, 16-cylinder V engine of roughly 50 litres, using turbocharging, aftercooling and the Cummins PT fuel system. Published ratings differ across generator-drive, drilling, marine and industrial versions. Before selecting internal or external components, identify the engine serial number, CPL, rating and installation so the quote follows the correct build rather than a generic KTA50 list.
- V16 architecture and approximately 50-litre displacement.
- PT fuel-system parts must be matched to the engine build and calibration.
- Cooling, exhaust and accessory arrangements vary by application.
KTA50 parts for planned overhaul and field repair
For planned engine work, we can quote cylinder liners, pistons and rings, bearings, connecting-rod parts, crankshaft-related components, gasket and seal kits, injectors and PT fuel parts, turbochargers, water pumps and oil pumps. A consolidated bill of materials reduces the risk of mixing revisions and makes it easier to coordinate genuine and OEM-equivalent options within the same repair plan.
- Major overhaul and power-cylinder components.
- Fuel-injection, air-handling and exhaust components.
- Cooling, lubrication, sealing and accessory components.
How to request KTA50 engine parts
Provide the engine serial number and CPL, equipment or genset model, required part numbers, quantities and destination. For an unnumbered component, send photographs showing casting marks, connector positions and dimensions. We will confirm the most likely match and identify any information still needed before the order is finalized.
