C-ATerpillar 3116 Series Fuel Injector 7E-8729

A high-performance fuel injector exclusively engineered for C-ATerpillar 3114, 3116, and 3126 diesel engines, the 7E-8729 combines rugged alloy steel 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 (E200B, EL200B), wheel loaders, asphalt pavers, and marine tracked 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 7E-8729 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 Shanghai Bocheng Auto Parts, Wuxi Welben Auto Parts, and DXM, it adheres to strict OEM specifiC-ATions and holds ISO 9001, CE, and CCC certifiC-ATions, guaranteeing seamless fitment and reliable operation across a wide range of C-ATerpillar equipment[1][2][3][5]. Constructed from high-strength alloy steel with precision-ground internal components and a hardened nozzle tip, it is built to withstand extreme pressures (up to 2000 MPa) and thermal stress inherent in 3116 engine operation, boasting a cycle life of over 1,000,000 injection cycles under load[2][4]. Every unit undergoes rigorous pre-shipment testing to verify precise fuel delivery, electrical performance, and zero leakage, eliminating defects right out of the box and ensuring consistent performance upon installation. As a direct replacement for the original 7E-8729 (with OEM numbers 7E8729 and CA7E8729), 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[1][4][7].

2. Physical Dimensions & Volume (Focus on Appearance)

The 7E-8729 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-8729 model[4][6][8]. Its solid alloy steel profile withstands severe vibration and mechanical stress during heavy-duty operation—critical for equipment used in construction and marine settings, such as excavators (E200B, EL200B) and marine tracked engines[1][3][7]. 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 and marine 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 (up to 2000 MPa)[2][4]. With a net weight ranging from 0.5 kg to 0.75 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][6][8][10].

3. Cross Reference & Generic Numbers

This table provides comprehensive cross-reference and generic number data for the 7E-8729 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-8729, directly corresponds to C-ATerpillar’s original equipment numbers (7E8729, CA7E8729), guaranteeing full fitment and compatibility with C-AT 3116 diesel engines[4][7][10]. The multi-hole nozzle confirms the precision nozzle specifiC-ATion, engineered to deliver optimal fuel atomization in C-AT 3116 fuel systems and perfectly matched to the 7E-8729 injector’s electromagnetic common rail design[4][6]. The listed generic numbers—most notably 0R-3190 and 127-8205, with which 7E-8729 is directly interchangeable—along with 0R-8479 and 162-0212, are widely recognized in the global aftermarket, simplifying replacement sourcing for parts suppliers and field technicians[3][5][7][10]. Full interchangeability across compatible injector models and engines (3114, 3116, 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 excavators and marine tracked engines[1][3][4][7].
