This is a Rayfuel aftermarket product for a Denso common-rail system. It is not presented as a genuine Komatsu or genuine Denso boxed component. Injector selection can vary with machine serial number, engine arrangement, market specification and emissions configuration, so the excavator model alone should not determine fitment.

The numbers 095000-6070 and 6251-11-3100 identify this listing. Similar Komatsu injectors, including nearby Denso references, may have a closely related exterior but different internal calibration, connections or application data. Do not assume that a similar-looking number is interchangeable.

095000-6070 Denso diesel fuel injector application and fitment

This injector is listed for selected PC400-8 and PC450-8 excavators equipped with the Komatsu SAA6D125E-5 engine family. Depending on the exact equipment configuration, catalogs may distinguish engine variants and serial-number ranges. Before purchase, compare both 095000-6070 and 6251-11-3100 with the original injector and verify the machine serial number through a reliable parts record.

Also compare the electrical terminal arrangement, spill or return connection, injector body, mounting features and nozzle profile shown in the gallery. These physical checks support identification but do not replace part-number confirmation.

Injector Function and Performance

A common-rail injector meters high-pressure diesel fuel and delivers controlled injection events into the combustion chamber. Correct operation supports dependable starting, stable combustion, responsive hydraulic work under load and consistent engine performance. Results also depend on clean fuel, correct rail pressure, sound wiring, suitable compression and the condition of the wider fuel system.

Common Signs This Injector May Need Replacing

• Hard starting or extended cranking
• Rough running or uneven cylinder contribution
• Reduced engine power under working load
• Increased exhaust smoke
• Abnormal combustion noise
• Excessive injector return flow
• Injector-related diagnostic fault codes

These symptoms do not prove injector failure. Low supply pressure, rail-pressure faults, contaminated diesel, damaged wiring, restricted filters and mechanical engine problems can cause similar complaints. Professional diagnosis and suitable injector testing are recommended before replacement.

Installation and Calibration

Installation should be completed by a qualified diesel technician using clean working practices. Protect all high-pressure connections from contamination, inspect associated pipes and return components, and renew required seals. Follow the correct Komatsu service procedure for the machine serial number. Where injector compensation or calibration data is required, complete the applicable registration process with suitable diagnostic equipment.

Before You Order

Please confirm OE number, engine model, machine serial number or old part photos before ordering. Verify 095000-6070 and 6251-11-3100 rather than relying only on PC400-8 or PC450-8. Komatsu provides general equipment information through its official website; exact injector fitment should follow the correct serial-number-based catalog. Use the Rayfuel contact page for number and photo comparison support.

The 095000-6070 Denso diesel fuel injector is an OE-number-matched aftermarket replacement for confirmed Komatsu SAA6D125E-5 applications and should not be selected solely by machine name.
