Cummins 6LT Excavator Engine options
The product selector includes 290 HP, 315 HP, 325 HP, 340 HP, 360 HP and 375 HP. Availability and the exact rating for the excavator configuration require supplier confirmation. Confirm the engine model, rated RPM and operating specification before selecting horsepower.

Excavator diesel engine fitment
Before ordering a Cummins 6LT Excavator Engine, provide the machine make, model and serial number. A clear photograph of the original engine identification plate is also important.
Your installer should compare the hydraulic pump drive, flywheel housing, coupling, engine mounts and sump arrangement. Cooling connections, intake routing, exhaust position and service access must also be checked.
Engine equipment and inclusions
Confirm the exact equipment supplied with your excavator diesel engine before purchase. The quotation and invoice should identify the engine build and its included accessories.
Do not assume that hydraulic pumps, a radiator, wiring loom, control equipment or every component shown in supplier photographs is included. Check the turbocharger, fuel system, starter motor, alternator and filter arrangement against the agreed specification.
Engine condition must also be confirmed in writing before ordering.
Preparing for installation
Have a qualified machinery technician assess the original engine failure and the requirements for the replacement installation. Cooling, fuel, intake and exhaust systems should be checked before the replacement engine is commissioned.
The technician should also confirm the required operating speed and compatibility with the machine’s hydraulic controls.

Cummins 6LT Excavator engine FAQs.
What horsepower options are available for the Cummins 6LT Excavator Engine?
The product selector includes 290 HP, 315 HP, 325 HP, 340 HP, 360 HP and 375 HP. Availability of each rating in the excavator configuration requires supplier confirmation.
Should I choose the highest horsepower available?
No. Your replacement engine must be matched to the machine’s hydraulic system and operating requirements. Do not select a higher output solely because it is available in the dropdown. Check the exact engine model, rated RPM and operating specification before selecting horsepower.
Is matching capacity and horsepower enough to confirm fitment?
No. Matching capacity or horsepower alone is not enough to establish compatibility. The engine’s operating speed, hydraulic pump connection, mounting arrangement, cooling system and external equipment must suit the intended excavator.
What details do you need about my machine?
Provide the machine make, model and serial number, together with a clear photograph of the original engine identification plate.
What should my installer compare?
Your installer should compare the hydraulic pump drive, flywheel housing, coupling, engine mounts and sump arrangement. Cooling connections, intake routing, exhaust position and service access must also be checked.
Are hydraulic pumps or a radiator included?
Do not assume that hydraulic pumps, a radiator, wiring loom, control equipment or every component shown in supplier photographs is included. The quotation and invoice should identify the engine build and its included accessories.
What should the technician check before commissioning?
Have a qualified machinery technician assess the original engine failure and the requirements for the replacement installation. Cooling, fuel, intake and exhaust systems should be checked before the replacement engine is commissioned, and the technician should confirm the required operating speed and compatibility with the machine’s hydraulic controls.
What should I confirm before purchasing?
Confirm the horsepower option, pump-drive compatibility, supplied equipment and freight requirements before purchasing your excavator diesel engine. Engine condition must also be confirmed in writing before ordering.
