095000-6290 Common Rail Injector for Komatsu 6D170E-5 Engine

6245-11-3100 Fuel Injector for Komatsu 6D170E-5 Engine

The 6245-11-3100 / 095000-6290 fuel injector assembly is used for Komatsu diesel engine fuel injection system applications. It is commonly searched as a common rail injector, injector assy, diesel fuel injector or Denso injector reference for Komatsu 6D170E-5 and SAA6D170E-5 engine repair.

This page focuses on 6245-11-3100 and 095000-6290 as the main part numbers. Before ordering, the removed injector should be checked by injector number, engine model, engine serial number, connector type, sealing parts, fuel system condition and ECU calibration requirements.

Komatsu 6D170E-5 Fuel Injection Application

The main engine references for this injector are Komatsu 6D170E-5 and SAA6D170E-5 series engines. Komatsu PC1250SP-8R is a common machine reference for this injector group, depending on engine configuration and machine serial number.

Some public listings may also mention heavy-duty Komatsu machine references such as HD465-7R. These should be treated as checking references only. Final fitment should be confirmed by the old injector number and engine nameplate before quotation.

Part Number Identification Notes

The main Komatsu part number for this page is 6245-11-3100. The Denso reference number commonly used with this injector is 095000-6290. No-hyphen search formats may include 6245113100 and 0950006290.

These number formats help with catalog checking and buyer inquiries. The injector should still be verified by the removed part, engine model, connector shape and fuel system requirements before shipment.

Common Rail Injector Function

A common rail injector controls fuel delivery into the combustion chamber under high fuel pressure. Correct injector performance affects engine starting, combustion stability, fuel consumption, exhaust smoke and engine power output.

For Komatsu 6D170E-5 engine applications, injector selection should be accurate. A wrong injector, contaminated fuel system or incorrect installation can cause rough running, smoke, engine derating, fuel leakage or repeated injector failure.

How to Identify the Correct 6245-11-3100 Injector

• Check whether the old injector number matches 6245-11-3100 or 095000-6290.

• Confirm the engine model, especially Komatsu 6D170E-5 or SAA6D170E-5 series references.

• Compare the injector connector, body shape and visible marking.

• Check whether sealing washers, O-rings or related installation parts need replacement.

• Confirm whether injector coding or calibration is required after installation.

• Use the engine serial number and machine model for final confirmation when the old number is unclear.

Common Failure Symptoms

• Hard starting caused by poor fuel atomization, low rail pressure or injector leakage.

• Rough idle or unstable engine speed caused by uneven fuel delivery.

• Black smoke caused by poor injection quality, air restriction, fuel system issues or engine load problems.

• Power loss under load when injector performance or fuel supply is insufficient.

• Fuel leakage around injector seat, high-pressure line or return line connection.

• Engine warning, derating or abnormal fuel correction caused by injector or fuel system faults.

Troubleshooting Before Replacement

Before replacing the 6245-11-3100 injector, inspect the complete fuel system. Injector symptoms may also come from poor fuel quality, blocked fuel filters, low rail pressure, wiring problems, ECU control issues or fuel contamination.

• Check fuel filter condition and replace contaminated filters before installing a new injector.

• Inspect fuel tank, fuel lines and fuel supply pump for contamination or air entry.

• Check high-pressure fuel line condition and tighten connections according to service procedure.

• Inspect injector harness connector and wiring condition if the engine reports electrical injector faults.

• Confirm whether the issue is caused by injector wear, rail pressure problems, pump issues or ECU control faults.

• Clean the injector seat and check sealing parts before final installation.

Installation and Maintenance Notes

• Keep the injector, fuel pipe and installation area clean during replacement.

• Replace sealing washers, O-rings or related sealing parts when required.

• Avoid dirt entry into the injector port or high-pressure fuel line.

• Install high-pressure lines carefully and avoid bending or forcing the pipe alignment.

• Complete injector coding or calibration if required by the engine control system.

• After installation, check for fuel leakage, abnormal smoke, idle stability and fault codes.

• Maintain clean diesel fuel and replace filters on schedule to reduce early injector failure.

Fitment Check Before Ordering

To reduce wrong orders, please send the old injector number, engine model, engine serial number, machine model, injector body photo, connector photo, fuel line connection photo and any visible Denso or Komatsu markings before quotation.

FAQ

Q: What is 6245-11-3100?
