222-5965 0r-9348 Diesel Fuel Injector for Cater-pillar 3126 Engine 0r-9348

This high-pressure common rail injector assembly (standard part identification code: 222-5965 / 2225965, common cross-reference and OE interchangeable numbers include 10R-1258, 10R1258, 222-5963, etc., mainly matched with 3126B, 3126E, and C7 series 7.2L diesel engine platforms, widely installed in tracked excavators, wheel loaders, graders, and heavy-duty engineering trucks) is precision-manufactured. As the core of micro-metering and ultra-fine spray execution in the electro-hydraulic injection system, it is responsible for accurately metering and dispersing high-pressure diesel fuel into micron-level atomized particles under microsecond-level electrical signal commands, promoting full mixing and combustion of fuel and intake air.

The product adheres to the manufacturing standards of "micron-level high-pressure atomization and millisecond-level ultra-fast response." The core needle valve assembly and internal valve core are made of aerospace-grade quenched special alloy steel, coated with a high-density, anti-coking hardened plating layer that effectively resists abrasion and jamming caused by diesel impurities. After installation, operators and maintenance personnel will experience a remarkably clear and intuitive improvement: cold starts are instantaneous, and vibrations at low idle speeds are completely eliminated; when facing high-load tunneling and heavy-load climbing conditions, the control lever and accelerator pedal respond swiftly and sensitively, providing rapid acceleration and continuous bursts of power, while significantly reducing black smoke from exhaust fumes, resulting in satisfactory fuel efficiency control and a smooth driving experience.

Open-pit mining and heavy loading operations: Wheel loaders and excavators continuously shovel and transport large blocks of ore in harsh, dusty, and high-load environments in mining areas, requiring extremely high stability in fuel supply and explosive power. When operators notice a decrease in digging force, severe idling vibration, or black smoke from the exhaust pipe, maintenance personnel should promptly replace the fuel injector with this high-precision model. After replacement, fuel injection atomization is extremely uniform, and the hydraulic system power output is restored to ample and stable levels, ensuring efficient progress in mining operations.

Construction and Heavy Transport Vehicle Scenarios: Construction trucks and heavy-duty dump trucks frequently start and climb hills in complex road conditions and dusty construction sites. When vehicles experience starting difficulties, severe idling vibrations, or uneven cylinder operation, the maintenance team replaces the entire set of high-specification fuel injection components. Precise electronic injection control allows the engine to instantly release high torque at low speeds, smoothly handling frequent start-stop cycles and heavy loads, ensuring efficient and smooth transportation operations.

Q: Can I use the product directly after installation? Is it necessary to enter a correction code?

A: Each injector has a unique flow correction code (IMA code) generated during factory testing. It is recommended to use a diagnostic tool to flash the correction code into the engine ECU after installation to achieve optimal fuel efficiency and smoothness.

Q: What is the inventory and delivery time for bulk purchases?

A: We have our own factory and large warehouse, and maintain a large inventory of this model year-round. Standard orders can be packaged and shipped within 24-48 hours, and large-volume orders can also be quickly scheduled for production line setup.

Q: How do you guarantee the quality and performance of your products before they leave the factory?

A: All injectors undergo assembly in a Class 100 cleanroom and 100% full-condition bench testing, covering key indicators suchs as sealing, pre-injection volume, full-load injection volume, and return oil volume. These stringent testing standards ensure that they are high-quality products from the outset.

Q: How long is the warranty period? What about after-sales service?

A: We offer a 12-month warranty period. If a performance failure occurs within the warranty period due to non-human factors, we provide rapid replacement or after-sales technical support to ensure your peace of mind when using our products.
