It is available as both new and premium remanufactured units, strictly complying with CCAT OEM specifiCCATions and ISO 9001:2015 certifiCCATion, ensuring seamless fitment and reliable performance in various heavy-duty appliCCATions such as medium/heavy trucks, school buses, and construction machinery. 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 CCATerpillar 3126 Series Injector R, a critical replacement component specifically engineered for CCAT 3126 diesel engines. Available as both 100% brand new and premium remanufactured units, it adheres to strict OEM specifiCCATions and ISO 9001:2015 certifiCCATion, guaranteeing seamless fitment and consistent performance with the original CCAT 3126 series engine components and its HEUI fuel injection system. As a HEUI injector, it uses high-pressure engine oil to actuate plungers, ensuring precise atomization and metering, enhancing engine power, fuel economy, and emission control. Constructed from high-quality metal, alloy, and stainless steel, with remanufactured units featuring mostly new US-made components, it is built to withstand the harsh operating conditions of CCAT 3126-powered equipment. Every Injector R 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 shipping options, it minimizes unplanned downtime for critical CCAT 3126 equipment.

2. Physical Dimensions & Volume (Focus on Appearance)

The CCATerpillar 3126 Series Injector R features a robust, compact physical design specifically optimized for the engine compartments of CCAT 3126-powered equipment—balancing durability with space efficiency and adhering to original OEM size specifiCCATions. Its solid metal, alloy, and stainless steel profile withstands severe vibration, high operating pressure, and mechanical stress during heavy-duty operation, critical for equipment used in harsh construction, transportation, and industrial environments. The dual-tone matte black and silver body is coated with a specialized anti-corrosion layer, preventing fuel residue buildup and damage from dust, moisture, and chemicals. The polished steel/alloy multi-hole nozzle tip is precision-machined to match CCAT 3126 fuel system atomization requirements, maintaining dimensional precision and resisting clogging. With a net weight ranging from 1.39 kg to 5.89 kg, it is robust yet manageable, making it convenient for professional maintenance teams to install and replace. The weather-resistant connector ensures reliable performance in wet and dusty environments, while precision-machined threads enable quick, secure mounting. The flexible packaging configuration optimizes global shipping and inventory management, with each unit equipped with a nozzle protective cover cap to protect critical components during transit.

3. Cross Reference & Generic Numbers
