C-ATerpillar 3116 Series Fuel Injector 7E-8727

A high-performance Mechanical Unit Injector (MUI) exclusively engineered for C-ATerpillar 3114 and 3116 diesel engines, the 7E-8727 combines rugged construction, precise dimensional craftsmanship, and comprehensive after-sales support to meet the harsh operating demands of C-ATerpillar construction, industrial, and marine equipment—including excavators (205B, 213B, 214B, 224B, E110B, E120B, E240B, E240C), asphalt pavers (AP-1000, AP-1050), backhoe loaders (446, 446B), and vibratory compactors (CB-434, CP-533). 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 7E-8727 fuel injector, a critical replacement component engineered specifically for C-ATerpillar 3116 diesel engines. Available as genuine C-AT or premium aftermarket variants from trusted suppliers like Guangzhou Cibo Diesel, Dongguan Truth Diesel, and Wuhan Jin Hong Auto Parts, it adheres to strict OEM specifiC-ATions and holds ISO 9001 certifiC-ATion, guaranteeing seamless fitment and reliable operation across a wide range of C-ATerpillar equipment[3][7][9]. Constructed from high-speed steel with a case-hardened needle seat and hardened nozzle tip, it is built to withstand the extreme pressures (40-120MPa) and thermal stress inherent in 3116 engine operation, leveraging a dual-spring structure to ensure precise injection control and optimal performance[8][9]. Every unit undergoes rigorous pre-shipment testing to verify precise fuel delivery and zero leakage, eliminating defects right out of the box and ensuring consistent performance upon installation. As a direct replacement for the original 7E-8727 (with OEM numbers 7E8727 and CA7E8727), it maintains the performance standards required for C-AT 3116 engines, reducing unplanned downtime for critical equipment, with in-stock availability to meet urgent maintenance needs[3][5][6][9].

2. Physical Dimensions & Volume (Focus on Appearance)

The 7E-8727 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 7E-8727 model[6]. Its solid high-speed steel profile withstands severe vibration and mechanical stress during heavy-duty operation—critical for equipment used in construction and industrial settings, such as excavators, asphalt pavers, and backhoe loaders[3][5][6]. 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 deliver C-AT’s patented S-type spray pattern, maintains dimensional precision and resists clogging, ensuring consistent fuel delivery under high pressure (40-120MPa)[8]. With a net weight of 0.78 kg, it balances robustness and ease of handling during installation and replacement, suitable for professional maintenance teams. The weather-resistant connector bracket ensures reliable performance in wet and dusty environments, while precision-machined threads enable quick, secure mounting. The flexible packaging configuration (neutral, original, or customized options) optimizes global shipping and inventory management, with each unit packaged in a high-strength box to prevent damage during transit[1][4][9].

3. Cross Reference & Generic Numbers

This table provides comprehensive cross-reference and generic number data for the 7E-8727 injector, a critical resource for global parts identifiC-ATion, ordering, and replacement, adhering to industry aftermarket cross-reference standards. The primary original part number, 7E-8727, directly corresponds to C-ATerpillar’s original equipment numbers (7E8727, CA7E8727), guaranteeing full fitment and compatibility with C-AT 3116 diesel engines[3][5][7]. The multi-hole mechanical nozzle confirms the precision nozzle specifiC-ATion, engineered to deliver C-AT’s patented S-type spray pattern for optimal fuel atomization in C-AT 3116 fuel systems and perfectly matched to the 7E-8727 injector’s dual-spring mechanical unit design[8]. The listed generic numbers—most notably 0R-3002 and 107-7732, with which 7E-8727 is directly interchangeable—along with 127-8216 and 127-8222, are widely recognized in the global aftermarket, simplifying replacement sourcing for parts suppliers and field technicians[3][7][9]. Full interchangeability across compatible injector models and engines (3114, 3116) 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 asphalt pavers[3][5][6].
