Compatible Machines and Applications

• s. It ensures accurate fuel delivery under extreme operating conditions, making it ideal for construction, mining, and large agricultural machinery.
• Equivalent / OEM Codes:
• Delphi: 400903-00074C
• Delphi: 40090300074C
• Alternate formats may appear as: 400903 00074C (spacing variation in catalogues)
• Engine Compatibility:
• Doosan DL06, DL06P series diesel engines
• Some compatibility with Perkins industrial platforms, depending on engine control calibration and injector mapping
• Compatible Equipment (examples):
• Doosan DX Series excavators (e.g. DX225LC, DX255LC with DL06 engines)
• Doosan wheel loaders and construction machinery
• Select Perkins-powered generators or pumps (limited, based on setup)
• Other industrial-grade stationary engines or power units requiring Delphi high-pressure systems
• Technical Notes:This injector is part of a Delphi electronic common rail system, capable of delivering fuel at extremely high pressures with exceptional precision. It contributes to lower fuel consumption, enhanced power output, and reduced emissions, especially in Tier 3 / Stage IIIA emissions-compliant systems. ECU coding and calibration is often required during replacement to ensure proper synchronization with the fuel management system.

Installation Advice

For the best engine performance we recommend replacing the complete set of injectors at the same time. New and worn injectors deliver fuel differently, and mixing them can cause uneven running. Please compare the part number on your old injector before ordering.
