This heavy-duty, electronically controlled hydraulic/unit diesel fuel injector assembly (Part ID: 100-7562 / 1007562; common OE cross-references include 0R-8769, 0R8769, 100-7563, 1007563, etc.) is precision-engineered for the 3116/3126 series of medium-to-heavy-duty diesel engines. It is widely used in 320B, 322B, and 325B series crawler excavators, trucks, construction machinery, and industrial generator sets. As a core component of the fuel system responsible for controlling diesel atomization quality and injection timing, it precisely meters fuel and rapidly disperses it into ultra-fine droplets under high-pressure commands, ensuring thorough mixing with intake air for optimal combustion.
Designed and manufactured to standards emphasizing "micro-level precision fit" and "millisecond-level responsiveness," the assembly features a core valve spool and needle valve set crafted from aerospace-grade, hardened special alloy steel. These components undergo ultra-precise geometric grinding and low-friction polishing, with surfaces finished in a dense, ultra-hard coating that effectively prevents internal scratching and pressure loss caused by fuel impurities. Upon installation, operators and technicians will notice immediate improvements: crisp, reliable cold starts and quiet, vibration-free idling. Whether climbing steep slopes, making frequent stops and starts, or cruising over long distances, the throttle response is sharp and agile, and acceleration is robust yet smooth. Additionally, the unit reduces black smoke emissions, delivering superior fuel efficiency and a stable, satisfying driving experience.
Manufactured and quality-controlled at the source in a standardized, smart factory. By eliminating issues often associated with intermediary distribution—such as excessive fit tolerances, uneven cylinder fuel delivery, and high-pressure leakage risks—this product offers a cost-effective solution that significantly reduces procurement expenses. End-to-end quality control based on standardized production facilities eliminates unnecessary markups and ensures highly consistent fuel injection pressure and flow rates across all cylinders; this reduces maintenance budgets while providing reliable, robust power for vehicle and equipment operations.
Rigorous testing on ultra-high-pressure digital dynamic test benches. To address issues common with low-quality replacements—such as response lag, pressure-release sticking (causing engine misfires and vibration), and wasted labor/costs from repeated installation and adjustment—every injection assembly undergoes automated testing before leaving the factory. Flow rates and sealing integrity are precisely calibrated across various pressure ranges in simulated high-temperature, ultra-high-pressure environments, ensuring "ready-to-install" performance and significantly saving time and costs associated with installation and tuning.
Large-scale warehousing and rapid shipping response. Recognizing that equipment used in daily operations and engineering projects represents high-utilization productivity tools—where fuel system failures lead to costly downtime and financial losses—our warehouse maintains ample stock year-round. Orders are packed and shipped within 24–48 hours of confirmation, drastically reducing logistics wait times and helping fleet operators and equipment owners quickly restore operations to avoid downtime losses.
Specialized quenched alloy needle valves and wear-resistant hardened coatings. Designed to combat premature wear and valve sticking caused by poor diesel lubricity or sulfur impurities in certain regions. Core components utilize high-hardness specialized bearing steel and anti-corrosion surface treatments, offering significantly enhanced fatigue and wear resistance; this ensures stable performance even under harsh conditions and prolonged, high-load operation, thereby reducing the extra expenses associated with frequent repairs.

Open-pit mining and construction excavation: Medium-sized crawler excavators operating continuously at mine sites and earthmoving projects often face prolonged periods of heavy loads and high-dust environments. When equipment experiences slow starting, severe idle vibration, or stalling under heavy loads, maintenance teams install this injector assembly. Precise fuel atomization enables the engine to deliver robust torque at low RPMs, ensuring smooth performance under heavy-load demands. High-load operation scenarios for heavy-duty construction machinery and generator sets: Trucks, construction equipment, and industrial emergency generators often operate continuously for long periods in the field, facing the challenges of heavy loads and harsh environments. When equipment exhibits slow starting, sluggish performance under load, or a noticeable increase in black exhaust smoke, technicians can promptly install this high-specification fuel injection component. Its robust and stable fuel supply enables the engine to deliver consistent torque, ensuring uninterrupted operation.
Q: Can the product be used immediately after installation, or is a correction code required?
A: Each fuel injector undergoes parameter calibration during factory testing. Provided the fuel lines are clean and new sealing rings are used, the unit can be put into service immediately after professional installation to standard torque specifications and the purging of air from the fuel system.
Q: What are the stock levels and lead times for bulk orders?
A: We operate our own factory and large-scale warehouses, maintaining substantial, year-round inventory for this model. Standard orders are typically packed and shipped within 24–48 hours, while bulk orders can be quickly scheduled for production.
Q: How are product quality and performance ensured before shipment?
A: All fuel injectors are assembled in Class 100 cleanroom environments and undergo 100% bench testing across all operating conditions. Tests cover critical metrics such as sealing integrity, pre-injection volume, full-load injection volume, and fuel return volume; our rigorous standards ensure that every unit shipped is of premium quality.
Q: What is the warranty period, and how is after-sales support handled?
A: We offer a 12-month warranty. Should a performance failure occur due to non-human factors within the warranty period, we provide rapid replacement or technical support to ensure your peace of mind.
