C-ATerpillar 3116 Series Fuel Injector 0R-8477

A high-precision electromagnetic common rail fuel injector exclusively engineered for C-ATerpillar 3116 diesel engines, the 0R-8477 integrates high-strength alloy steel construction, precise dimensional craftsmanship, and comprehensive after-sales support to meet the harsh operating demands of C-ATerpillar construction, industrial, and heavy-duty equipment—including excavators (E320B, E325B) and trucks powered by 3116 engines. Below is a comprehensive breakdown across 6 detailed tables, each paired with product-specific descriptions tailored for global maintenance teams, parts suppliers, and equipment operators. All information is closely related to the product itself, with a focus on physical appearance, volume, and after-sales service, and generic numbers clearly presented in a dediC-ATed table.

1. Basic Product Information

This table outlines the core identity, compatibility, and quality standards of the 0R-8477 fuel injector, a premium replacement component engineered specifically for C-ATerpillar 3116 diesel engines. Manufactured by trusted aftermarket brands like HuParts and HK REAL STRENGTH TRADE LIMITED, with origin in China, it meets or exceeds C-ATerpillar’s original equipment specifiC-ATions, holds multiple certifiC-ATions including ISO 9001 and CE, and ensures full compatibility and reliable performance[1][6][9]. Constructed from high-strength metal with precision-ground internal components and high-temperature resistant seals, it withstands the heavy loads, continuous operation, and harsh environmental conditions of C-AT construction and industrial machinery, including excavators (E320B, E325B) and trucks powered by 3114, 3116, and 3126 engines[1][3][9][10][11][12]. Every unit undergoes rigorous pre-shipment testing to eliminate defects, ensuring seamless integration with compatible engines, stable fuel delivery, and consistent performance, with in-stock availability for immediate delivery[1][11][12]. The premium core materials resist corrosion, wear, and thermal fatigue, making the injector ideal for long-hour operations in construction sites and industrial facilities. As a direct replacement for the OEM 0R-8477, it maintains the performance standards required for C-AT 3116 engines, ensuring reliability and reducing unplanned downtime for critical equipment—note that we recommend replacing the entire set of injectors to ensure optimal engine performance, as mixing genuine and aftermarket parts may cause issues due to differences in oil output and atomization concentration[1][12].

2. Physical Dimensions & Volume (Focus on Appearance)

The 0R-8477 injector features a rugged, compact physical design specifically optimized for the tight engine compartments of various C-AT equipment powered by 3116 engines, balancing durability with space efficiency and adhering to original size specifiC-ATions for the 0R-8477 model[1][4][6][9]. Its solid metal profile withstands severe vibration and mechanical stress during heavy-duty operation—critical for equipment used in construction and industrial settings, such as E320B, E325B excavators and trucks powered by 3114, 3116, and 3126 engines[1][3][9][10][11][12]. 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, engineered to match C-AT 3116 atomization requirements, maintains dimensional precision and resists clogging, ensuring consistent fuel delivery under high pressure[3][10]. With a net weight ranging from 0.7 kg to 1.0 kg and gross weight of 1.0 kg (with accessories), it balances robustness and ease of handling during installation and replacement, suitable for professional maintenance teams[4][9]. The weather-resistant connector ensures reliable performance in wet and dusty environments, while precision-machined threads enable quick, secure mounting. The flexible packaging configuration (two standard size options) optimizes global shipping and inventory management, with neutral or original packaging options available to meet diverse supplier needs[4][9].

3. Cross Reference & Generic Numbers

This table provides comprehensive cross-reference and generic number data for the 0R-8477 injector, a critical resource for global parts identifiC-ATion, ordering, and replacement, adhering to industry aftermarket cross-reference standards. The primary original part number, 0R-8477, directly corresponds to C-ATerpillar’s original equipment numbers (0R8477, CA0R8477), guaranteeing full fitment and compatibility with C-AT 3116 diesel engines[1][3][10][11][12]. The OEM-spec nozzle code confirms the precision nozzle specifiC-ATion, engineered to deliver optimal fuel atomization in C-AT 3116 fuel systems and perfectly matched to the 0R-8477 injector’s MUI-type electromagnetic common rail design[3][10]. The listed generic numbers, most notably 127-8211 (with which 0R-8477 is directly interchangeable), along with 1278211 and CA1278211, are widely recognized in the global aftermarket, simplifying replacement sourcing for parts suppliers and field technicians[1][3][10]. Full interchangeability across compatible injector models and engines (3114, 3126) 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 3116-powered equipment like E320B, E325B excavators and trucks[1][3][9][10][11][12].
