CCATerpillar 3126 Series Fuel Injector 222-5966

The 222-5966 fuel injector is a high-precision, OEM-compatible replacement component exclusively engineered for CCATerpillar 3126B, 3126E diesel engines (also compatible with CCAT C7 engines[6]), strictly complying with CCAT OEM specifiCCATions and industry quality standards. It is fully compatible with a wide range of CCAT 3126-powered equipment, including excavators, wheel loaders, and trucks[1][3][4], delivering stable 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 dediCCATed 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 222-5966 fuel injector, a critical replacement component specifically engineered for CCATerpillar 3126B, 3126E diesel engines (and CCAT C7 engines[6]). Available as 100% brand new aftermarket units[2][6], it adheres to strict OEM specifiCCATions, guaranteeing seamless fitment and consistent performance with the original CCAT 3126 series engine components and its common rail fuel system. As a common rail injector, it uses ECM-controlled solenoid valves for precise atomization and metering, enhancing engine power, fuel economy, and emission control. Constructed from high-quality steel/metal[2], it is built to withstand the harsh operating conditions of CCAT 3126-powered equipment, including excavators, wheel loaders, and trucks[1][3][4], ensuring durability and reliability in diverse environments. Every 222-5966 unit undergoes rigorous pre-shipment testing, eliminating defects right out of the box and ensuring it is ready for direct installation. With in-stock availability and prompt delivery[1][4][5][6], it minimizes unplanned downtime for critical CCAT 3126 equipment, making it a trusted choice for maintenance teams and parts suppliers worldwide.

2. Physical Dimensions & Volume (Focus on Appearance)

The 222-5966 injector features a robust, compact physical design specifically optimized for the engine compartments of CCAT 3126B, 3126E-powered equipment—balancing durability with space efficiency and adhering to original OEM size specifiCCATions (22×13×13 cm[7], 29×12.5×12.5 cm[6] package dimensions). Its solid steel/metal[2] profile withstands severe vibration, high operating pressure from the common rail system, and mechanical stress during heavy-duty operation, critical for equipment used in harsh construction and industrial environments, including excavators, wheel loaders, and trucks[1][3][4]. The dual-tone matte black and silver 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 steel multi-hole nozzle tip is precision-machined to match CCAT 3126 common rail fuel system atomization requirements, maintaining dimensional precision and resisting clogging, ensuring consistent fuel delivery under high pressure and improved combustion efficiency. With a net weight of 1.5 kg (3.31 lbs)[2][6] to 1.85 kg (4.08 lbs)[7], it is robust yet manageable, making it convenient for professional maintenance teams to install and replace, even in narrow engine bays. 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 make it ideal for the tight engine bays of CCAT 3126B, 3126E-powered equipment. The flexible packaging configuration (original, neutral, or customized[1][2][4][5][7]) 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[2][6][7].

3. Cross Reference & Generic Numbers

This table provides comprehensive cross-reference and generic number data for the 222-5966 injector, a critical resource for global parts identifiCCATion, ordering, and replacement, adhering to industry aftermarket cross-reference standards. The original part number, 222-5966, directly corresponds to CCATerpillar’s original equipment numbers (2225966[6][7]) and is fully interchangeable with a range of widely recognized generic numbers, including 10R-0781, 10R0781[1][6], 135-5459, 173-9268, 173-9379, 174-7526, 179-6020, 180-7431, 198-7912, 20R-4148, 204-2467, 232-1168, 232-1171, 232-1183, and 156-3895[3][4][5]. These generic numbers are commonly used in the global aftermarket, as all belong to the same fuel injector group for CCAT 3126 series engines, simplifying replacement sourcing for parts suppliers and field technicians. The 222-5966 injector features a common rail design, engineered to deliver optimal atomization (via multi-hole nozzle) required for CCAT 3126B, 3126E, and C7 common rail fuel systems[6], ensuring efficient combustion, enhanced engine power, fuel economy, and emission control, while being compatible with low-sulfur, low-lubricity diesel fuels. Full interchangeability across compatible injector models and engines reduces inventory complexity and ensures flexible maintenance solutions for CCAT 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[3][4][6].
