C-ATerpillar 3116 Series Fuel Injector 0R-3389

A high-performance mechanical fuel injector exclusively engineered for C-ATerpillar 3116 diesel engines, the 0R-3389 combines high-speed steel construction, precise dimensional design, and comprehensive after-sales support to meet the harsh operating demands of C-ATerpillar construction, agricultural, and industrial equipment—including excavators, wheel loaders, medium-duty trucks, and industrial generators. 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.

1. Basic Product Information

This table outlines the core identity, compatibility, and quality standards of the 0R-3389 fuel injector, a premium replacement component engineered specifically for C-ATerpillar 3116 diesel engines. Manufactured by trusted brands like ERIKC and DYD ERIKC, it meets or exceeds C-ATerpillar’s original equipment specifiC-ATions and holds ISO 9001 certifiC-ATion, ensuring full compatibility and reliable performance[1][4]. Constructed from high-speed steel, it withstands the heavy loads, continuous operation, and harsh environmental conditions of C-AT construction, agricultural, and industrial machinery[1]. Every unit undergoes rigorous pre-shipment testing on professional test benches to eliminate defects, ensuring seamless integration with 3116 engines, stable fuel delivery, and consistent performance, with in-stock availability for immediate delivery[1][3]. The premium core materials, including precision-ground stainless steel nozzles and heat-resistant FKM O-rings (70 Shore A hardness), resist corrosion, wear, and thermal fatigue, making the injector ideal for long-hour operations in construction sites, farms, and industrial facilities. As a direct replacement for the OEM 0R-3389, it maintains the performance standards required for C-AT 3116 engines, ensuring reliability and reducing unplanned downtime for critical equipment[1][7][10].

2. Physical Dimensions & Volume (Focus on Appearance)

The 0R-3389 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[1]. At 202 mm in total length and 36.2 mm in maximum diameter, its solid high-speed steel profile withstands severe vibration and mechanical stress during heavy-duty operation—critical for equipment used in construction, agriculture, and industrial settings. 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 stainless steel nozzle tip, engineered to match C-AT 3116 atomization requirements and paired with code 7E-8952, maintains dimensional precision and resists clogging, ensuring consistent fuel delivery under high pressure[3][8]. With a net weight of 0.55 kg and gross weight of 1.5 kg (including heavy-duty packaging), it balances robustness and ease of handling during installation and replacement[1]. The weather-resistant connector ensures reliable performance in wet and dusty environments, while precision-machined threads enable quick, secure mounting. The standard 10-units-per-carton configuration optimizes global shipping and inventory management, with neutral or ERIKC-branded packaging options available to meet diverse supplier needs[1].

3. Cross Reference & Generic Numbers

This table provides comprehensive cross-reference and generic number data for the 0R-3389 injector, a critical resource for global parts identifiC-ATion, ordering, and replacement, adhering to industry aftermarket cross-reference standards[6]. The primary original part number, 0R-3389, directly corresponds to C-ATerpillar’s original equipment numbers (0R3389, CA0R3389), guaranteeing full fitment and compatibility with C-AT 3116 diesel engines[3][8]. The nozzle code 7E-8952 (and its variants 7E8952, CA7E8952) confirms the precision nozzle specifiC-ATion, engineered to deliver optimal fuel atomization in C-AT 3116 fuel systems[3][8]. The listed generic numbers, including 7E-8952, 4P-2995, 0R-8471, and 0R-8483, are widely recognized in the global aftermarket, simplifying replacement sourcing for parts suppliers and field technicians[4][8]. Full interchangeability across compatible injector models 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[4][6][8].
