Main Features

Power Cylinder Package - Proven single-piece ferrous cast ductile iron pistons and cooling nozzles for maximum 

durability and reliability - combined with an advancedpiston design that uses nitrided liners and cast-iron top rings to handle 

high injection pressures and provide a 10% longer 

life-to-overhaul compared to two-piece pistons.

High Pressure Modular Common Rail (MCR) Fuel System - Cummins high pressure fuel pump and modular 

common rail system provides full-authority electronic control of the fuel pump and injectors for precise control of both 

injection pressure and timing. Each injector includes its own integrated accumulator, which helps to eliminate pressure

pulsation between injectors and improve stability.

Prelub™ System - Eliminates wear from cold and hot starts - increases life-to-overhaul by as much as 25%. 

Integral or remote mounting options.

Quantum System Electronics - High-speed Electronic Control Module (ECM) with a self-cooling mount is 

isolated from detrimental vibration loading. A field-proven, fully-sealed wiring harness with fail-safe connectors integrates 

the ECM with the engine sensors for optimized engine performance, monitoring and protection. Quantum system

technology is ideal for tough mining applications that demand continuous uptime carrying hundreds of tons capacity.

Fleetguard® ES Filtration - The two off-engine first stage (suction-side) filters provide 7 micron filtration and 

include water separation capability. The three second stage (pressure-side) filters are mounted on-engine and provide 

3 micron filtration downstream of the gear pump. Service interval for both filter stages is 250 hours.

Advanced Engine Monitoring - Allows you to monitor engine performance cylinder by cylinder on a real-time basis. 

Also provides trending charts to help you keep preventive maintenance to a minimum without risking engine damage.

Two-Stage Cummins Oil Filters - Combination full-flow and bypass filtration to effectively remove harmful 

sludge and up to three times as many contaminants to reduce engine


Premium Fan Drive – Incorporates large matched and sealed bearings, improved oil seals, and an improved 

idler system. The fan drives have fixed fan centers with tensioning provided by a manually adjusted and maintenance 

free idler. The fan drive is available with or without an electronically controlled oil-actuated fan clutch.
