C-ATerpillar 3116 Series Fuel Injector 0R-3190

A premium mechanical fuel injector exclusively engineered for C-ATerpillar 3114 and 3116 diesel engines, the 0R-3190 integrates rugged alloy steel construction, precise dimensional control, and comprehensive after-sales support to meet the harsh operating demands of C-ATerpillar construction, agricultural, and industrial equipment—including excavators (E200B, EL200B), wheel loaders (910E, 910F), integrated tool carriers (IT12B, IT14B, IT14F), 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-3190 fuel injector, a premium replacement component engineered specifically for C-ATerpillar 3114 and 3116 diesel engines. Manufactured to meet or exceed C-ATerpillar’s original equipment specifiC-ATions and certified by ISO 9001, it is constructed from high-strength alloy steel and high-speed steel to withstand the heavy loads, continuous operation, and harsh environmental conditions of C-AT construction, agricultural, and industrial machinery[1][7]. Every unit undergoes three critical pre-shipment tests to eliminate defects, ensuring seamless integration with 3114/3116 engines, stable fuel delivery, and consistent performance, with in-stock availability for immediate delivery[1][4][7]. The premium core materials, including precision-ground stainless steel nozzles and heat-resistant FKM O-rings, 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-3190, it maintains the performance standards required for C-AT 3114/3116 engines, ensuring reliability and reducing unplanned downtime for critical equipment like E200B excavators and 910E wheel loaders[4].

2. Physical Dimensions & Volume (Focus on Appearance)

The 0R-3190 injector features a rugged, compact physical design specifically optimized for the tight engine compartments of various C-AT equipment powered by 3114/3116 engines, balancing durability with space efficiency and adhering to original size specifiC-ATions[1][7]. At 198 mm in total length and 35.8 mm in maximum diameter, its solid alloy steel and 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 3114/3116 atomization requirements and paired with code 7E-8729, maintains dimensional precision and resists clogging, ensuring consistent fuel delivery under high pressure[4][5]. With a net weight of 0.53 kg and gross weight of 0.60 kg (or 1.5 kg with heavy-duty packaging), it balances robustness and ease of handling during installation and replacement[7]. 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, reducing logistics costs for parts suppliers, with flexible packaging options available[7].

3. Cross Reference & Generic Numbers

This table provides comprehensive cross-reference and generic number data for the 0R-3190 injector, a critical resource for global parts identifiC-ATion, ordering, and replacement. The primary original part number, 0R-3190, directly corresponds to C-ATerpillar’s original equipment numbers (0R3190, CA0R3190), guaranteeing full fitment and compatibility with C-AT 3114/3116 diesel engines[2][4]. The nozzle code 7E-8729 confirms the precision nozzle specifiC-ATion, engineered to deliver optimal fuel atomization in C-AT 3114/3116 fuel systems[4][5]. The listed generic numbers, including 7E-8729, 4P-2995, 0R-8477, and 0R-8473, are widely recognized in the global aftermarket, simplifying replacement sourcing for parts suppliers and field technicians[1][4][5]. 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 3114/3116-powered equipment like E200B excavators and 910E wheel loaders[1][4].
