The c-aterpillar 10R-1265 injector is a high-precision core component exclusively developed for c-aterpillar 3412 series engines, perfectly compatible with 3412E, 3412C, 3412TTA and 3408E engines. It adopts advanced electronic control monomer injection (MEUI) technology, integrates c-aterpillar's original precision manufacturing process with high-strength wear-resistant materials, and is specially designed for the high-load, high-pressure and harsh working conditions of construction, mining, marine and industrial power fields. Featuring pencil-type needle valve design and high-pressure atomization technology, it can directly replace original parts, quickly restore engine power performance, reduce equipment downtime and long-term operation costs, and fully meet the operation needs of heavy-duty equipment under complex working conditions[1][2].
Core Parameters & Compatibility
| Parameter Item | Specific Specific-ations | Core Value |
| Applicable Engine Models | 3412E, 3412C, 3412TTA, 3408E, 3412 | 100% matches the original engine's injection parameters, avoiding power fluctuation, difficult startup and fuel leakage caused by mismatched injectors, ensuring seamless adaptation and stable operation, especially suitable for c-aterpillar D8 bulldozers, 345C excavators and other heavy equipment[4][6]. |
| Technology Type | Advanced Electronic Control Monomer Injection (MEUI) Technology | Equipped with pencil-type needle valve and porous nozzle design, realizes precise control of injection timing, fuel volume and pressure through ECM, supports multi-stage injection strategy (pre-injection + main injection + post-injection), and ensures stable power output for long-term high-load operation[1][2]. |
| Product Material | Tungsten carbide coated nozzle, high-strength precision alloy plunger, surface anti-corrosion hardening treatment, hardness up to HRC70[1][3]. | Enhances wear resistance, corrosion resistance and high-temperature resistance, prevents damage from dirty fuel and harsh working conditions, avoids needle valve jamming, and its service life is 3 times that of ordinary injectors[1][3]. |
| Product Status | New (Original Standard)/Remanufactured (ISO 9001 & c-at Certified) | New parts fully comply with c-aterpillar original factory standards; remanufactured parts pass strict multi-channel testing and 1000-hour salt spray test, with reliable quality and high cost performance, meeting different budget needs of enterprises[1][3]. |
| Replacement Compatible Models | 178-0199, 222-5966, 3920206, 10R-1262 | Multi-model cross-compatibility, reducing the difficulty of spare parts procurement and inventory pressure for enterprises, improving maintenance efficiency, and suitable for cross-border e-commerce supply[1][5]. |
| Warranty Service | 15 months warranty for new parts; 12 months warranty for remanufactured parts (unlimited mileage) | Covers parts quality, needle valve jamming, injection pressure deviation and installation-related faults, providing professional technical support and after-sales maintenance services, eliminating use worries[3]. |
Core Performance Advantages
| Advantage Dimension | Technical Highlights | Practical Applic-ation Effect |
| Precision Injection & Uniform Atomization | Pencil-type needle valve (low inertia), precision-drilled spray holes, 100% flow balance test, injection error ≤ ±1.0%, atomized particle diameter ≤ 50μm, maximum injection pressure up to 2000bar[1][2]. | Ensures full fuel combustion, reduces carbon deposition in the cylinder (residual carbon ≤ 0.1mg/hole), avoids needle valve jamming, makes the engine run smoothly with low noise, and optimizes power output stability[1][3]. |
| Superior Durability & Reliability | Strict heat treatment process, anti-erosion nozzle design, high-pressure resistant sealing structure, IP68 sealing grade, compatible with high-sulfur and low-sulfur diesel, can withstand 200 million injection cycles[1][3]. | Service life is up to 7200 hours, adapting to high-temperature, high-pressure and high-dust harsh working conditions, reducing maintenance frequency and downtime loss, and withstanding 1-meter water immersion for 30 minutes[1][3]. |
| Efficient Energy Saving & Emission Reduction | Optimized injection structure, efficient combustion design, adapting to low-lubricity fuels and biofuels, solenoid valve opening time ≤ 0.15ms[1][6]. | Reduces fuel consumption by 12%-16%, saves long-term operation costs, and meets Euro V emission standards (NOx emission ≤ 3.5g/kWh), complying with global environmental protection requirements[1][3]. |
| Intelligent Control & Easy Maintenance | Built-in pressure sensor, real-time communic-ation with ECM, fault self-diagnosis function, compatible with c-at ET4.9 diagnostic instrument, original factory size and interface for direct replacement[1][3]. | Installation time is shortened to 20 minutes per unit, easy to diagnose and maintain, can quickly loc-ate faults through fault codes, reducing maintenance time and labor costs[3]. |
