C-ATerpillar 3116 Series Fuel Injector 107-7732

A high-performance electromagnetic common rail fuel injector exclusively engineered for C-ATerpillar 3116, 3114, and 3126 diesel engines, the 107-7732 combines durable high-strength material construction, precise dimensional craftsmanship, and comprehensive after-sales support to meet the harsh operating demands of C-ATerpillar construction, industrial, excavator, and truck equipment equipped with the 3116 engine platform. Adhering to OEM standards, it offers reliable performance, seamless replacement, and global availability, 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 107-7732 fuel injector, a critical replacement component engineered specifically for C-ATerpillar 3116, 3114, and 3126 diesel engines. Available as genuine C-AT or premium aftermarket variants from trusted suppliers, it adheres to strict OEM specifiC-ATions and delivers reliable performance across a wide range of C-ATerpillar equipment, including popular excavator models like 320B, 322B, and M320, as well as loaders and asphalt pavers[2][3][4][6]. As an electromagnetic common rail injector, it features advanced electromagnetic control to ensure precise fuel delivery and atomization, critical for optimizing engine efficiency, power, and emission control—key requirements for modern heavy-duty equipment[1][7]. Constructed from high-strength alloy steel and precision components, it is built to withstand the harsh operating conditions of construction and industrial environments, ensuring durability and long-term performance. 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 107-7732 (with OEM numbers 1077732 and CA1077732), it maintains the performance standards required for C-AT 3116 engines, reducing unplanned downtime for critical equipment, with in-stock availability and stable production capacity to meet global demand[5][7].

2. Physical Dimensions & Volume (Focus on Appearance)

The 107-7732 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 OEM size specifiC-ATions for the 107-7732 model[3][4][6]. Its solid alloy steel profile withstands severe vibration and mechanical stress during heavy-duty operation—critical for equipment used in construction and industrial appliC-ATions. 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 match C-AT 3116 atomization requirements, maintains dimensional precision and resists clogging, ensuring consistent fuel delivery under high pressure[1][7]. With a net weight of 0.82 kg (1.8 lbs), it balances robustness and ease of handling during installation and replacement, suitable for professional maintenance teams. The weather-resistant electromagnetic connector bracket ensures reliable electrical connection and 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) make it ideal for the narrow engine bays of C-AT 3116-powered equipment, including excavators and loaders[3][4][6]. The flexible packaging configuration (original or neutral options) optimizes global shipping and inventory management, with each unit packaged to protect critical components, including the electromagnetic module, during transit[5][7].

3. Cross Reference & Generic Numbers

This table provides comprehensive cross-reference and generic number data for the 107-7732 injector, a critical resource for global parts identifiC-ATion, ordering, and replacement, adhering to industry aftermarket cross-reference standards. The primary original part number, 107-7732, directly corresponds to C-ATerpillar’s original equipment numbers (1077732, CA1077732), guaranteeing full fitment and compatibility with C-AT 3116, 3114, and 3126 diesel engines[1][5][7]. The multi-hole nozzle confirms the precision nozzle specifiC-ATion, engineered to deliver optimal atomization required for C-AT 3116 fuel systems and perfectly matched to the 107-7732 injector’s electromagnetic common rail design, ensuring efficient combustion, power output, and emission control[1][7]. The listed generic numbers—most notably OR-8682 and 127-8216, with which 107-7732 is directly interchangeable—are widely recognized in the global aftermarket, as all three parts belong to the same fuel injector group, simplifying replacement sourcing for parts suppliers and field technicians[2][3][4][6]. Full interchangeability across compatible injector models and engines (3116, 3114, 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 loaders[2][3][4][6].
