C-ATerpillar 3116 Series Fuel Injector OR-8473

A high-reliability, OEM-standard fuel injector exclusively engineered for C-ATerpillar 3116 diesel engines, the OR-8473 (also marked as 0R-8473, 0R8473) integrates high-strength material construction, precise dimensional craftsmanship, and comprehensive after-sales support to meet the harsh operating demands of C-ATerpillar equipment—including excavators, wheel loaders, backhoes, skid steers, generators, and other industrial power units equipped with the 3116 engine platform. Adhering to strict OEM specifiC-ATions, with ISO 9001, CE, and E-mark certifiC-ATions, and boasting a stable global supply capacity (up to 100 pieces per month), it offers reliable performance, seamless replacement, and flexible service, suitable for global maintenance teams, parts suppliers, and equipment operators. Below is a comprehensive breakdown across 6 detailed tables, each paired with product-specific descriptions, focusing on physical appearance, volume, and after-sales service, with 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 OR-8473 fuel injector, a critical replacement component engineered specifically for C-ATerpillar 3116 diesel engines. Available as genuine C-AT or premium aftermarket/remanufactured variants from trusted suppliers, it adheres to strict OEM specifiC-ATions (ISO 9001, CE, E-mark certified) and is directly interchangeable with 127-8213, 101-8673, 4P-1734, and other listed generic numbers, guaranteeing seamless fitment across a wide range of C-ATerpillar equipment—from excavators and wheel loaders to industrial power units[2][7][9]. As a mechanical injector tailored for 3116 engines, it is designed to work with low-sulfur, low-lubricity fuels, delivering precise fuel atomization (S-type spray pattern) and delivery that avoids power and fuel efficiency losses associated with low-quality alternatives, perfectly matching the 3116 engine’s mechanical injection system and 40-120MPa operating pressure range[11]. Constructed from high-strength alloy steel with precision internal components (needle and valve clearance 1-3μm), it is built to withstand the harsh operating conditions of C-AT 3116 engines, ensuring reliable performance in construction, mining, and industrial appliC-ATions[11]. Every unit undergoes rigorous pre-shipment testing covering spray pattern, leakage, and fuel delivery accuracy to verify reliability, eliminating defects right out of the box. As a direct replacement for the original OR-8473 (with OEM numbers 0R-8473, 0R8473 and CA0R8473), it maintains the performance standards required for C-AT 3116 engines, reducing unplanned downtime, with in-stock availability (2-7 working days delivery) and stable supply (up to 100 pieces per month) to meet global demand[2][6][7].

2. Physical Dimensions & Volume (Focus on Appearance)

The OR-8473 injector features a rugged, compact physical design specifically optimized for the tight engine compartments of various C-AT equipment powered by 3116 engines—from excavators and wheel loaders to industrial power units—balancing durability with space efficiency and adhering to original OEM size specifiC-ATions for the OR-8473 model[1][4]. Its solid alloy steel profile withstands severe vibration, the 40-120MPa operating pressure range, and mechanical stress during heavy-duty operation, critical for equipment used in construction, mining, and industrial appliC-ATions where harsh conditions are common[11]. 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 environments. The polished metal nozzle tip, precision-machined to match C-AT 3116 atomization requirements (S-type spray pattern), maintains dimensional precision and resists clogging, ensuring consistent fuel delivery under high pressure for the mechanical injection design[11]. With a net weight ranging from 0.75 kg to 1.0 kg, it balances robustness and ease of handling during installation and replacement, suitable for professional maintenance teams. The weather-resistant connector bracket (where applicable) ensures reliable performance in wet and dusty environments, while precision-machined threads enable quick, secure mounting. Its streamlined design and compact profile (8.8 inches in length, 5.1 inches in width) make it ideal for the narrow engine bays of C-AT 3116-powered equipment[1]. The flexible packaging configuration (neutral, original, or bulk options) optimizes global shipping and inventory management, with each unit equipped with a nozzle protective cover cap to protect critical components during transit[4][5][7].

3. Cross Reference & Generic Numbers

This table provides comprehensive cross-reference and generic number data for the OR-8473 injector, a critical resource for global parts identifiC-ATion, ordering, and replacement, adhering to industry aftermarket cross-reference standards. The primary original part number, OR-8473, directly corresponds to C-ATerpillar’s original equipment numbers (0R-8473, 0R8473, CA0R8473) and is fully interchangeable with 127-8213, 101-8673, 4P-1734, and other listed generic numbers, guaranteeing full fitment and compatibility with C-AT 3116 diesel engines[2][9]. The mechanical injection design confirms the injector’s precision, engineered to deliver optimal atomization (S-type spray pattern) required for C-AT 3116 fuel systems and perfectly matched to the OR-8473 injector’s design, ensuring efficient combustion, power output, and emission control, even with low-sulfur fuels, while adapting to the 40-120MPa operating pressure range[11]. The listed generic numbers—most notably 127-8213, 101-8673, and 4P-1734, with which OR-8473 is directly interchangeable—are widely recognized in the global aftermarket, as all belong to the same fuel injector group for C-AT 3116 engines, simplifying replacement sourcing for parts suppliers and field technicians[2][9]. Full interchangeability across compatible injector models and engines 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 excavators and wheel loaders[4][6][8].
