CCATerpillar 3126 Series Fuel Injector 169-7408

The 169-7408 fuel injector is a high-precision, OEM-compatible replacement component exclusively engineered for CCATerpillar 3126 and 3126B diesel engines[4][6], adhering to strict CCAT OEM specifiCCATions and ISO certifiCCATions[7]. It is fully compatible with a wide range of CCAT 3126-powered equipment, including excavators, trucks, and other construction machinery[3][6], 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 169-7408 fuel injector, a critical replacement component specifically engineered for CCATerpillar 3126 and 3126B diesel engines[4][6]. Available as brand new units[1][3][6][7], it adheres to strict OEM specifiCCATions and ISO certifiCCATions[7], guaranteeing seamless fitment and consistent performance with the original CCAT 3126 engine components and its common rail fuel system[9]. As a common rail-type injector[3][4][6], it delivers precise atomization and metering controlled by the ECM, enhancing engine power, fuel economy, and emission control, while avoiding power and fuel efficiency losses associated with low-quality alternatives. Constructed from high-speed steel[1], it is built to withstand the harsh operating conditions of CCAT 3126-powered equipment, including excavators, trucks, and marine vehicles[2][3][6], ensuring durability and reliability in diverse environments. Every 169-7408 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 stable supply capacity (up to 10000 pieces annually[3][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 169-7408 injector features a compact, rugged physical design specifically optimized for the engine compartments of CCAT 3126-powered equipment—from excavators and trucks[3][6] to marine vehicles[2]—balancing durability with space efficiency and adhering to original OEM size specifiCCATions[2][3]. Its solid high-speed steel profile[1] withstands severe vibration, high operating pressure from the common rail fuel system[9], and mechanical stress during heavy-duty operation, critical for equipment used in harsh construction, industrial, and marine 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 saltwater (for marine appliCCATions[2]) commonly encountered in field operations. The polished stainless steel nozzle tip is precision-machined to match CCAT 3126 common rail atomization requirements[9], maintaining dimensional precision and resisting clogging, ensuring consistent fuel delivery under high pressure and improved combustion efficiency. With a net weight of 3.31 lbs (1.5 kg)[2], it is robust yet lightweight, making it convenient for professional maintenance teams to install and replace, even in narrow engine bays or marine engine compartments. The weather-resistant connector bracket ensures reliable performance in wet, dusty, and saltwater environments, while precision-machined threads enable quick, secure mounting. Its streamlined design and compact profile (13.78 inches in length, 3.94 inches in width, 5.12 inches in height) make it ideal for the tight engine bays of CCAT 3126-powered equipment. The flexible packaging configuration (neutral as standard[3][6][10]) 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 (21×8×6 cm[2]) designed to align with global shipping standards.

3. Cross Reference & Generic Numbers

This table provides comprehensive cross-reference and generic number data for the 169-7408 injector, a critical resource for global parts identifiCCATion, ordering, and replacement, adhering to industry aftermarket cross-reference standards. The original part number, 169-7408, directly corresponds to CCATerpillar’s original equipment number (1697408) and is fully interchangeable with a range of widely recognized generic numbers, including 20R-4148[1][2][7], 173-4061, 232-1168[2], 364-8024, 456-3493[3], 174-7527, 222-5967[5], and 1731012, 155-1819[6]. These generic numbers are commonly used in the global aftermarket, as all belong to the same fuel injector group for CCAT 3126 engines, simplifying replacement sourcing for parts suppliers and field technicians. The 169-7408 injector features a common rail design[3][4][6], engineered to deliver optimal atomization required for CCAT 3126 common rail fuel systems[9], ensuring efficient combustion, enhanced engine power, fuel economy, and emission control. 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][6][7].
