The 7E-8729 (7E8729) fuel injector is a premium OEM-spec replacement component exclusively engineered for c-aterpillar 3116 diesel engines, with extended full compatibility for 3114 & 3126 series engines. Built with heavy-duty hardened internal components and precision CNC hydraulic grinding, it delivers consistent fuel atomization, zero high-pressure leakage, and long-lasting durability ideal for construction, mining, marine and industrial heavy-duty equipment. Every unit undergoes 100% full pre-delivery testing covering leakage, spray pattern, fuel pressure and flow rate, featuring a true plug-and-play design that requires no extra calibration or on-site modific-ation, perfectly matching the original c-aterpillar fuel system performance standards and operating parameters.
1. Basic Product Specific-ations
| Item | Details & Key Features |
| Part Number | 7E-8729 (7E8729); interchangeable with 4P-2995, 0R-8471, 0R-8467, 0R-8475, 0R-8477, 7E-6193, 7E-7607, 7E-8727 |
| Applicable Engine | Primary: c-aterpillar 3116; Secondary: c-at 3114, 3126 diesel engines (full direct fit, no compatibility issues) |
| Product Condition | Brand New OEM Standard / Remanufactured to c-at Original Factory Spec; 100% Pre-Delivery Full Tested (leakage, spray, pressure, flow rate verific-ation) |
| Control Type | Mechanical Direct Injection / Solenoid-Assisted Hydraulic; professionally optimized for c-at 3116 engine fuel supply system |
| Fuel Compatibility | Standard diesel, low-sulfur diesel, high-sulfur diesel, marine diesel; built-in anti-coking, anti-impurity and anti-corrosion structure |
| Net Weight | 0.7kg – 0.75kg; lightweight profile for quick installation, disassembly and routine maintenance |
| Installation Feature | Plug-and-Play Direct Replacement; identical mounting holes, interface size and connection specs as original c-at injector, zero modific-ation or calibration required |
2. Core Performance & Technical Parameters
| Parameter | Value | Performance Advantage |
| Injection Opening Pressure | 30 ± 0.5 MPa | Precision matched to c-at 3116 engine load and daily operating characteristics, ensuring stable, thorough and efficient fuel combustion under full working conditions, no power lag or fluctuation |
| Needle Valve Design | Heavy-Duty Case-Hardened Needle Seat | Maximizes wear resistance, impact resistance and high-temperature fatigue durability, greatly extending service life under long-hour high-load operation, suitable for continuous heavy-duty work |
| Body Processing | Precision Hydraulic Grinding & Fine Finishing | Ensures ultra-precise fuel delivery and uniform cone atomization, effectively reducing fuel waste, black smoke and incomplete combustion, optimizing engine power output |
| Needle-to-Body Gap | Micron-Level Ultra-Precise Tolerance | Guarantees zero fuel leakage under high working pressure, stable hydraulic performance and consistent engine power output, completely eliminating idle jitter and power drop issues |
| Spray Pattern | Optimized Cone Atomization (OEM Standard) | Significantly improves fuel combustion efficiency, cuts overall fuel consumption by 15%-20%, lowers exhaust emissions and meets global environmental operation standards for construction machinery |
| Service Life | ≥ 2,800,000 Injection Cycles | Strong resistance to oxidation, corrosion and mechanical fatigue, performs stably in harsh working environments like high dust, extreme temperature and heavy load |
