Cummins KTA50 Engine Parts Guide
Everything a buyer needs to source Cummins KTA50 parts — the 50.3-litre V16 used in mining trucks, drills and large gensets — including the high-wear components we stock and how to quote by part number.
About the Cummins KTA50
The Cummins KTA50 is part of the K50 family: a 50.3-litre, 16-cylinder V-configuration diesel engine. The "KTA" designation means turbocharged and aftercooled. It is a workhorse in surface mining haul trucks, blast-hole drills, large stationary and mobile generator sets, and marine applications. Because it runs in demanding, high-load duty cycles, operators tend to reorder the same wear items on a predictable schedule — which is exactly where sourcing by part number pays off.
Common KTA50 wear and overhaul parts
These are the KTA50 components we are asked to quote most frequently:
- Injectors and injector cups / sleeves
- Fuel pumps (PT-type) and fuel lines
- Piston kits, cylinder liners, rings and bearings
- Cylinder heads, head gaskets and grommet/seal kits
- Turbochargers and turbo rebuild kits
- Water pumps, oil coolers and thermostats
- Complete filter sets and gasket/seal overhaul kits
Ordering KTA50 parts by number
Cummins part numbers are the most dependable way to order. If you have a rebuild kit number or individual component numbers, send them over. If not, give us the engine serial number (the dataplate is on the block) and the application, and we will cross-reference the correct parts for your build — the KTA50 has had running changes over its production life, so confirming the serial avoids mismatched components.
