It is fully compatible with a wide range of CCAT 3126-powered equipment, including excavators, loaders, trucks, gensets, combines, and marine machinery, 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 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 135-5459 fuel injector, a critical replacement component specifically engineered for CCATerpillar 3126 7.2L diesel engines, with a primary focus on 3126B, 3126E, and 3116 variants[2][5]. Available in brand new or premium aftermarket variants from trusted manufacturers like Cibo, Ziedel, and Otto[1][2][7], it adheres to strict OEM specifiCCATions and ISO standards[4][8], guaranteeing seamless fitment and consistent performance with the original CCAT 3126 engine components and its HEUI fuel system[3]. As a HEUI-type injector tailored to the 3126 engine’s design[2][3], it leverages high-pressure engine oil to actuate fuel injection, delivering precise atomization and metering controlled by the ECM[3], enhancing engine power, fuel economy, and emission control, while avoiding power and fuel efficiency losses associated with low-quality alternatives. Constructed from high-strength alloy steel with precision internal components[4], it is built to withstand the harsh operating conditions of CCAT 3126-powered equipment, including excavators, loaders, and trucks[5], ensuring durability and reliability in construction, transportation, marine, and industrial environments. Every 135-5459 unit undergoes rigorous pre-shipment testing[6][9], eliminating defects right out of the box and ensuring it is ready for direct installation. With in-stock availability[7] and stable supply capacity[1][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 135-5459 injector features a rugged, durable physical design specifically optimized for the engine compartments of CCAT 3126 7.2L-powered equipment—from excavators (322C, 325C[5]) and loaders (950G II, 962G II[5]) to trucks and marine engines—balancing durability with space efficiency and adhering to original OEM size specifiCCATions[10]. Its solid high-strength alloy steel profile withstands severe vibration, high operating pressure from the HEUI fuel system[3], and mechanical stress during heavy-duty operation, critical for equipment used in harsh construction, transportation, marine, and industrial environments. The 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 and marine operations. The polished stainless steel nozzle tip is precision-machined to match CCAT 3126 HEUI atomization requirements[3], maintaining dimensional precision and resisting clogging, ensuring consistent fuel delivery under high pressure and improved combustion efficiency. With a net weight ranging from 1.8 kg (3.97 lbs) to 2.2 kg (4.85 lbs), it balances robustness and ease of handling, 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, dusty, and marine environments, while precision-machined threads enable quick, secure mounting. Its streamlined design and compact profile (16.54 inches in length, 4.53 inches in width, 7.40 inches in height) make it ideal for the engine bays of CCAT 3126-powered equipment. The flexible packaging configuration (neutral or original options[1][6][7][9]) 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 135-5459 injector, a critical resource for global parts identifiCCATion, ordering, and replacement, adhering to industry aftermarket cross-reference standards. The original part number, 135-5459, directly corresponds to CCATerpillar’s original equipment numbers (1355459) and is fully interchangeable with a range of widely recognized generic numbers, including 10R7053, 0R9439, 1340467, 20R5615, 222-5966, 180-7431, 128-6601[2][6][7][9]. These generic numbers are commonly used in the global aftermarket, as all belong to the same fuel injector group for CCAT 3126 7.2L engines (3126B, 3126E, 3116), simplifying replacement sourcing for parts suppliers and field technicians. The 135-5459 injector features a HEUI design, powered by high-pressure engine oil and controlled by the ECM[3], engineered to deliver optimal atomization required for CCAT 3126 HEUI fuel systems, 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.
