C-ATerpillar 3126 Series Fuel Injector 1OR-9239

The 1OR-9239 fuel injector is a high-precision, OEM-compatible replacement component exclusively engineered for C-ATerpillar 3126 diesel engines, including 3126A, 3126B, and 3126E variants, adhering to strict C-AT OEM specifiC-ATions and ISO 9001 certified standards. It is fully compatible with C-AT 3126-powered equipment, including excavators, wheel loaders, medium-duty trucks, and industrial generators, delivering exceptional performance, seamless fitment, and comprehensive after-sales support. Below is a detailed breakdown across 6 tables, each paired with product-specific descriptions, focusing on physical appearance, volume, and after-sales service, with cross-reference/generic numbers clearly presented in a dediC-ATed table. All content is detailed, product-focused, and fully in English.

1. Basic Product Information

This table outlines the core identity, compatibility, and quality standards of the 1OR-9239 fuel injector, a critical replacement component specifically engineered for C-ATerpillar 3126 diesel engines (including 3126A, 3126B, 3126E variants). Available in brand new, remanufactured, or premium aftermarket variants, it adheres to ISO 9001 certifiC-ATion and strict OEM specifiC-ATions, guaranteeing seamless fitment and consistent performance with the original C-AT 3126 engine components. As an electromagnetic common rail injector tailored to the 3126 engine’s design, it is controlled by the ECU to deliver precise fuel atomization and metering, avoiding power and fuel efficiency losses associated with low-quality alternatives. Constructed from high-strength alloy steel with precision internal components, it is built to withstand the harsh operating conditions of C-AT 3126-powered equipment, ensuring durability and reliability in construction, mining, and industrial environments. Every 1OR-9239 unit undergoes rigorous pre-shipment testing to verify spray pattern, leakage, and electrical performance, eliminating defects right out of the box and ensuring it is ready for direct installation. With stable supply and in-stock availability (3-15 working days delivery), it minimizes unplanned downtime for critical C-AT 3126 equipment, making it a trusted choice for maintenance teams and parts suppliers worldwide.

2. Physical Dimensions & Volume (Focus on Appearance)

The 1OR-9239 injector features a rugged, compact physical design specifically optimized for the tight engine compartments of C-AT 3126-powered equipment—from excavators and wheel loaders to medium-duty trucks and industrial generators—balancing durability with space efficiency and adhering to original OEM size specifiC-ATions. Its solid alloy steel profile (hardness HRC58-62) withstands severe vibration, high operating pressure (up to 2000 MPa), and mechanical stress during heavy-duty operation, critical for equipment used in harsh construction, mining, and industrial environments. The semi-matte black body is coated with a specialized anti-corrosion and anti-carbon layer, preventing fuel residue buildup and damage from dust, moisture, and chemicals commonly encountered in field operations. The polished metal nozzle tip, precision-machined to match C-AT 3126 atomization requirements, maintains dimensional precision (seal surface roughness Ra≤0.1μm) and resists clogging, ensuring consistent fuel delivery under high pressure. With a net weight ranging from 4.5 lbs to 5.0 lbs (and up to 13.0 lbs for some variants), it balances robustness and ease of handling, making it convenient for professional maintenance teams to install and replace. The weather-resistant connector bracket ensures reliable performance in wet and dusty environments, while precision-machined threads enable quick, secure mounting. Its streamlined design and compact profile (12.5 inches in length, 4.9 inches in width, 5.1 inches in height) make it ideal for the narrow engine bays of C-AT 3126-powered equipment. The flexible packaging configuration (neutral, original, or bulk options) optimizes global shipping and inventory management, with each unit equipped with a nozzle protective cover cap to protect critical components during transit, and package dimensions designed to align with global shipping standards.

3. Cross Reference & Generic Numbers

This table provides comprehensive cross-reference and generic number data for the 1OR-9239 injector, a critical resource for global parts identifiC-ATion, ordering, and replacement, adhering to industry aftermarket cross-reference standards. The original part number, 1OR-9239, directly corresponds to C-ATerpillar’s original equipment numbers (1OR9239, CA1OR9239) and is fully interchangeable with a range of widely recognized generic numbers, including 10R-9239, 0R-9350, 222-5972, and 162-9610. These generic numbers are commonly used in the global aftermarket, as all belong to the same fuel injector group for C-AT 3126 engines (3126A, 3126B, 3126E), simplifying replacement sourcing for parts suppliers and field technicians. The 1OR-9239 injector features an electromagnetic common rail design, controlled by the ECU via a solenoid valve, engineered to deliver optimal atomization required for C-AT 3126 fuel systems, ensuring efficient combustion, power output, and emission control, even with low-sulfur fuels. Full interchangeability across compatible injector models and engines reduces inventory complexity and ensures flexible maintenance solutions for C-AT equipment operators, making it easier to source compatible parts in urgent situations. This cross-reference data ensures that users can accurately identify and order the correct injector, minimizing downtime for critical 3126-powered equipment, and aligns with the cross-reference standards of trusted global diesel parts suppliers.
