3126 Series Injector 153-5938 Product Details

The 153-5938 fuel injector is a premium OEM-compatible replacement component exclusively engineered for 3126, 3126B, and 3126E series diesel engines—widely utilized in heavy-duty equipment such as vocational trucks, excavators, wheel loaders, industrial power units, and construction machinery. Meticulously engineered to meet and exceed rigorous OEM standards, this injector integrates advanced HEUI (Hydraulic Electronic Unit Injection) technology, high-grade wear-resistant materials, and strict quality control protocols, delivering exceptional operational stability, fuel efficiency, and durability in extreme working conditions (high temperature, high pressure, long-term heavy load, and low-quality fuel environments). Available in both brand-new and premium remanufactured variants, it ensures seamless compatibility with the original engine system, providing reliable support for consistent engine power output and reduced maintenance frequency. Below are the detailed specifications, cross reference numbers (common numbers), core performance features, material & craftsmanship, quality testing standards, and application & warranty information, presented in 6 comprehensive tables, each paired with an in-depth description closely related to the product itself.

1. Basic Product Specifications

The table above details the core basic parameters of the 153-5938 injector, which is custom-developed for 3126 series engines and also compatible with 3406E industrial engines to ensure perfect fit and consistent performance. Its 300-450 HP horsepower range is precisely calibrated to match the power output requirements of the target engines, balancing power and fuel efficiency without compromising engine performance or service life. As a HEUI system injector, it integrates hydraulic pressure and electronic control, delivering more precise fuel injection timing (±0.1ms accuracy) and duration compared to traditional injectors, which is crucial for improving combustion efficiency, reducing fuel waste, and lowering exhaust emissions (CO, NOx)—consistent with the functional demands of modern injectors and global environmental standards. With a net weight of 3.0 lbs and OEM-standard dimensions, the injector enables direct, hassle-free installation without any modifications to the engine or fuel system, reducing installation time and labor costs. The injection pressure of up to 29,000 psi ensures ultra-fine fuel atomization for complete combustion, while its compatibility with low-sulfur and low-lubricity diesel fuels enhances its adaptability to diverse regions and harsh fuel conditions, making it suitable for both industrial and construction equipment scenarios.

2. Cross Reference Numbers (Common Numbers)

This table comprehensively presents all cross reference numbers (common numbers) for the 153-5938 injector, covering genuine OEM part numbers (including the CA1535938 variant), high-quality aftermarket equivalents, and direct replacement part numbers—an essential feature for users seeking compatible replacement components. All listed cross references have undergone rigorous compatibility testing, ensuring that the 153-5938 injector can directly replace any component with the corresponding reference number, eliminating the risk of part mismatch during purchase and installation. For users replacing worn or damaged injectors in 3126 series engines or compatible industrial engines, these common numbers provide unparalleled convenience, enabling quick identification of the correct replacement part, minimizing equipment downtime, and reducing overall maintenance costs. Notably, it is fully compatible with widely used OEM numbers such as 153-5939 and 127-8210, as well as aftermarket number 8N7008, ensuring wide applicability across different engine models and equipment types, and aligning with the reliability requirements of genuine injectors.

3. Core Performance Features

The core performance of the 153-5938 injector focuses on precision, durability, and adaptability—key attributes that ensure reliable operation in 3126 series engines and compatible industrial engines. Its HEUI injection technology combines hydraulic and electronic control, delivering precise fuel delivery that promotes complete combustion, reduces fuel waste, and lowers exhaust emissions (CO, NOx), meeting global environmental standards and the efficiency requirements of modern heavy-duty engines. The coated plungers, high-speed steel components with hard chrome plating address the common issue of wear in harsh industrial and construction working conditions, significantly extending the injector’s service life and avoiding the power and fuel efficiency losses associated with reverse-engineered aftermarket brands. The high-sensitivity solenoid valve ensures rapid response to engine operating changes, maintaining stable performance even under heavy load and frequent load fluctuations. Additionally, the dual-variant option provides users with flexible choices based on budget, while the anti-clogging and low-fuel adaptability design enhances its applicability in diverse regions and working environments, making it ideal for heavy-duty equipment.
