C-ATerpillar 3116 Series Fuel Injector 101-4561

A high-performance common rail fuel injector exclusively engineered for C-ATerpillar 3116 diesel engines, the 101-4561 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, and truck equipment—including excavators, trucks, and other heavy machinery equipped with the 3116 engine platform. 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 101-4561 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, 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[1][3][6][8]. Constructed from high-strength alloy steel with precision-ground internal components and a hardened nozzle tip, it is built to withstand the high pressure and thermal stress inherent in 3116 engine operation, ensuring durability and long-term performance in harsh construction, industrial, and commercial vehicle environments[3][6][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 101-4561 (with OEM numbers 1014561 and CA1014561), it maintains the performance standards required for C-AT 3116 engines, reducing unplanned downtime for critical equipment, with in-stock availability and large supply capacity to meet urgent maintenance needs[1][3][6][8].

2. Physical Dimensions & Volume (Focus on Appearance)

The 101-4561 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 101-4561 model[3][7]. Its solid alloy steel profile withstands severe vibration and mechanical stress during heavy-duty operation—critical for equipment used in construction, industrial, and commercial vehicle appliC-ATions, such as excavators and trucks[1][3][6][8]. 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[3][6][9]. With a net weight of 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 (original or neutral options) optimizes global shipping and inventory management, with each unit packaged to protect critical components during transit[1][3][6][7].

3. Cross Reference & Generic Numbers

This table provides comprehensive cross-reference and generic number data for the 101-4561 injector, a critical resource for global parts identifiC-ATion, ordering, and replacement, adhering to industry aftermarket cross-reference standards. The primary original part number, 101-4561, directly corresponds to C-ATerpillar’s original equipment numbers (1014561, CA1014561), guaranteeing full fitment and compatibility with C-AT 3116 diesel engines[2][3][6]. 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 101-4561 injector’s common rail design, ensuring efficient combustion and reliable performance[3][9]. The listed generic numbers—most notably 102-7038, 105-1694, 0R-3190, and 0R-4374, with which 101-4561 is directly interchangeable—are widely recognized in the global aftermarket, simplifying replacement sourcing for parts suppliers and field technicians[3][4][6]. Full interchangeability across compatible injector models and engines (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 trucks[1][3][4][6].
