267-3361 2673361 Diesel Engine Parts Common Rail Fuel Injector for Ca-t C9 330d 340d 336D Excavator

This industrial-grade electronically controlled HEUI (Hydraulic Electronic Unit Injection) diesel engine injector (OE No.: 267-3361, common Reman remanufactured part No.: 10R-7224) is a high-precision core component of the fuel system specifically developed for Cater-pillar C7 series high-power medium-duty diesel engines. The product is perfectly compatible with Cater-pillar 324D, 325D, and 329D series tracked excavators, M325D series wheeled excavators, as well as classic construction machinery such as the D6N tracked bulldozer and 950H and 962H series wheel loaders. As a precision fuel terminal driving the entire machine, it employs cutting-edge hydraulic servo control and micro-hole machining technology, specifically designed to handle high-intensity, harsh construction site operations. When your equipment is equipped with this precision injector system, the engine's performance will undergo a noticeable change: intermittent misfiring and severe engine vibration caused by fuel supply failures will completely disappear, and the engine will produce a smooth and rhythmic roar. When facing demanding conditions and pressing the accelerator deeply, the horsepower output will be continuous and extremely linear, and the previously persistent thick smoke from the exhaust pipe will be instantly cleared, restoring the machine to its full power potential.

Direct sales from our own factory and ample stock: Many overseas buyers are often constrained by long cross-border shipping cycles and markups from multiple layers of agents, resulting in expensive construction machinery sitting idle on construction sites and incurring huge daily losses. We have a technologically advanced self-built manufacturing base and maintain a large-scale inventory of the classic 267-3361 model. This fully closed-loop, first-hand supply chain model allows for lightning-fast delivery within 24-48 hours of your order, helping you minimize losses from downtime and supply disruptions with factory-direct pricing and efficient delivery speed.

Rigorous Digital Bench Testing and Ultra-Hard Nano-Coating: Addressing the shortcomings of low-end replacement parts on the market, such as insufficient wear resistance and susceptibility to internal leakage or even seizing when faced with diesel fuel of varying quality, every injector we manufacture undergoes multi-dimensional digital bench calibration, including pressure matching, dynamic flow rate, and high-pressure atomization of the hydraulic control unit. Its core control valve needle has been comprehensively upgraded with a high-specification DLC (diamond-like carbon) ultra-hard nano-coating process, structurally resolving the starting weakness caused by early wear and maintaining consistent durability under harsh operating conditions.

Original Factory-Grade Injection Angle Calibration and Outstanding Fuel Efficiency: Addressing the issue of sluggish mechanical power, excessively high cylinder temperatures, and abnormally high fuel consumption caused by flow deviations from original factory calibration, this product undergoes rigorous three-dimensional precision grinding based on CAT OEM parameters. The nozzle's multi-hole design ensures that, under the high-pressure drive of the HEUI system, diesel atomization particles achieve micron-level uniformity and fineness, resulting in excellent mixing with the air in the cylinder. This not only completely eliminates the persistent problem of black smoke from vehicles but also significantly improves fuel conversion efficiency, helping overseas users substantially save on hourly fuel costs during long-term operation.

Municipal Infrastructure and Road High-Load Tunneling Construction: At urban road or bridge construction sites with tight schedules, a Cater-pillar 325D tracked excavator equipped with a C7 engine is continuously breaking and loading heavy loads onto a layer of hard concrete. Due to the large-scale, high-frequency dynamic changes in frontal resistance, the engine is prone to stalling and hesitancy. The 267-3361 injector, with its extremely high hydraulic servo airtightness, opens and closes in microseconds upon receiving electronic control commands, ensuring powerful and efficient injections, making digging movements agile and responsive, and ensuring steady progress of the project.

Large Quarries and Heavy-Duty Earthwork Transportation in Mines: In the heart of open-pit mines, where dust obscures the sky and temperature fluctuations are extreme, Cater-pillar 950H wheel loaders loaded with tens of tons of crushed stone shuttle back and forth along long, steep inclines. Facing heavy loads climbing slopes, operators must maintain high throttle output to prevent engine speed drops. This injector, under extremely high working rail pressure, maintains a stable and perfect fuel mist pattern, ensuring complete fuel combustion and guaranteeing that the loader can continuously extract huge torque even at low speeds, easily traversing steep slopes and preventing misfires caused by fuel supply pulsations.
