095000-0800 095000-0801 Injector Ass'y for Komatsu SA6D125E 6D125 Engine

095000-0800 / 095000-0801 Common Rail Injector for Komatsu 6D125 Engine

The 095000-0800 / 095000-0801 common rail injector is supplied for Komatsu diesel engine fuel injection system repair. It is commonly searched as 095000-0800, 0950000800, 095000-0801, 0950000801, 6156-11-3100, fuel injector, common rail injector or injector assembly for Komatsu 6D125 and SA6D125E engine applications.

This page focuses on 095000-0800 and 095000-0801 as the main injector numbers. 6156-11-3100 can be used as a Komatsu checking reference. Final fitment should be confirmed by the old injector number, engine model, injector connector, fuel pipe connection, injector body marking and machine information before ordering.

Engine and Machine Application

The main engine references for this injector are Komatsu 6D125, SA6D125E and SAA6D125E-3. The current product page lists PC400-7, PC450-7 and WA470-5 as application references, which should be kept because they match the heavy equipment search direction of this injector.

For this product page, the SEO Title should cover Komatsu PC400-7 and PC450-7 machine search intent, while the H1 should reinforce the Komatsu SA6D125E engine and common rail injector direction. This gives the page broader search coverage without turning it into a general Komatsu injector catalog.

Machine model alone is not enough for final injector confirmation. Komatsu machines can vary by engine arrangement, production range and fuel system configuration. The old injector marking and physical comparison are more reliable than the model name alone.

Part Number and Reference Notes

095000-0800 and 095000-0801 are the main injector numbers of this product page. The compact formats 0950000800 and 0950000801 should also be included because buyers may search without hyphens.

6156-11-3100 is a useful Komatsu reference number for this injector direction. It should be included in the top parameters and body content, but the page should still keep 095000-0800 / 095000-0801 as the primary injector signal.

Do not add every nearby Komatsu injector number into this page unless the old injector or supplier data confirms interchange. Similar injector numbers can vary by calibration, connector, fuel pipe connection and engine configuration.

How to Confirm the Correct Injector

Common rail injectors can look similar, but small differences in injector code, connector type, body marking, fuel pipe connection and calibration may affect engine performance. Before ordering, compare the removed injector carefully.

• Confirm whether the old injector number is 095000-0800, 095000-0801, 0950000800 or 0950000801.

• Check whether the Komatsu reference number is 6156-11-3100 or 6156113100.

• Confirm whether the engine is Komatsu 6D125, SA6D125E or SAA6D125E-3.

• Compare the connector type, plug position and injector body shape.

• Check fuel pipe connection, nozzle side and mounting position.

• Send old injector photos before quotation if you are not sure.

Common Injector Failure Symptoms

A common rail injector may need replacement when the engine has hard starting, rough idle, black smoke, white smoke, fuel knock, loss of power, high fuel consumption, unstable cylinder performance or abnormal fault codes related to fuel injection.

These symptoms are not always caused by the injector itself. Dirty fuel, blocked fuel filter, weak high pressure pump, air in the fuel line, injector harness problems, ECU control issues or low compression can create similar problems.

During repair, check the fuel filter, fuel line, high pressure pump, return flow, injector harness and cylinder condition together with the injector. Replacing only the injector without checking fuel quality may lead to repeated failure.

Single Injector and Full Set Ordering

This injector can be ordered as a single replacement piece when only one injector has failed. For full engine repair, buyers may also request a matched set according to the number of cylinders and the old injector configuration.

For Komatsu 6D125 and SA6D125E engine repair, confirm whether you need one injector for maintenance replacement or multiple injectors for a complete engine service. The old injector numbers should match before mixing new and existing injectors.

Installation and Maintenance Notes

Before installation, clean the injector seat, fuel pipe connection and surrounding area. Do not allow dust, metal particles or dirt to enter the common rail fuel system.

Use the engine service manual for installation procedure, tightening torque and fuel system bleeding. After installation, check for fuel leakage, abnormal smoke, stable idle and normal engine response.

For common rail systems, clean fuel is critical. Replace the fuel filter on time and inspect the fuel tank if the old injector failed because of contamination, water or metal debris.

Buying Notes for Repair Shops and Parts Distributors

For repair shops, this 095000-0800 / 095000-0801 injector is suitable for Komatsu 6D125 and SA6D125E engine fuel injection repair when the old injector is worn, blocked, leaking or unable to deliver stable injection performance.

For parts distributors, it can be supplied as a Komatsu common rail injector reference for PC400-7, PC450-7, WA470-5 and related heavy equipment service demand. Topvelsun supports small repair orders and bulk inquiries. Please send the required quantity, old injector number, engine model, machine model and photos of the old injector.
