C-ATerpillar 3116 Series Fuel Injector 127-8220

A premium, OEM-standard fuel injector exclusively engineered for C-ATerpillar 3114, 3116, and 3126 diesel engines, the 127-8220 integrates high-strength anti-rust steel construction, precise dimensional craftsmanship, and industry-leading after-sales support to meet the harsh operating demands of C-ATerpillar construction machinery, excavators, wheel loaders, industrial power units, and heavy-duty equipment equipped with the 3116 MUI engine platform. Adhering to strict OEM specifiC-ATions, with ISO certifiC-ATion and stable global supply capacity, 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 127-8220 fuel injector, a critical replacement component engineered specifically for C-ATerpillar 3114, 3116 (MUI), and 3126 diesel engines. Available as genuine C-AT or premium aftermarket variants from trusted suppliers, it adheres to strict OEM specifiC-ATions (ISO certified) and is directly interchangeable with 0R8467, 0R8682, 9Y-4982, 0R0471, and 101-4561, guaranteeing seamless fitment across a wide range of C-ATerpillar equipment—from excavators to wheel loaders and industrial power units[1][3][6][9]. As an electromagnetic common rail injector tailored for 3116 MUI engines, it delivers precise fuel atomization and delivery, critical for optimizing engine efficiency, power, and emission control—key requirements for modern heavy-duty equipment used in construction and industrial appliC-ATions[1][3][6]. Constructed from high-grade anti-rust steel with precision internal components, it is built to withstand harsh operating conditions, ensuring long service life and resistance to corrosion, a common concern in heavy-duty environments[2][3][5]. Every unit undergoes rigorous pre-shipment testing covering multiple performance aspects to verify reliability, eliminating defects right out of the box. As a direct replacement for the original 127-8220 (with OEM numbers 1278220 and CA1278220), it maintains the performance standards required for C-AT 3116 engines, reducing unplanned downtime, with timely shipping (3-4 working days for genuine variants) and stable supply to meet global demand[5][8].

2. Physical Dimensions & Volume (Focus on Appearance)

The 127-8220 injector features a rugged, compact physical design specifically optimized for the tight engine compartments of various C-AT equipment powered by 3116 (MUI) engines—from excavators to wheel loaders and industrial power units—balancing durability with space efficiency and adhering to original OEM size specifiC-ATions for the 127-8220 model[3][5][6]. Its solid high-grade anti-rust steel profile withstands severe vibration, high pressure, and mechanical stress during heavy-duty operation, critical for equipment used in construction and industrial appliC-ATions where harsh conditions are common[2][3][5]. 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 MUI atomization requirements, maintains dimensional precision and resists clogging, ensuring consistent fuel delivery under high pressure for the electromagnetic common rail design[2][3][6]. With a net weight of 1.0 kg (2.20 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 performance in wet and dusty environments, while precision-machined threads enable quick, secure mounting. Its streamlined design and compact profile (8.46 inches in length) make it ideal for the narrow engine bays of C-AT 3116-powered equipment[5][6]. The flexible packaging configuration (neutral, original, or bulk options) optimizes global shipping and inventory management, with genuine variants packaged in original C-ATerpillar packaging and each unit equipped with a nozzle protective cover cap to protect critical components during transit[5][8].

3. Cross Reference & Generic Numbers

This table provides comprehensive cross-reference and generic number data for the 127-8220 injector, a critical resource for global parts identifiC-ATion, ordering, and replacement, adhering to industry aftermarket cross-reference standards. The primary original part number, 127-8220, directly corresponds to C-ATerpillar’s original equipment numbers (1278220, CA1278220, CA0R8467) and is fully interchangeable with 0R8467, 0R8682, 9Y-4982, 0R0471, 101-4561, and 127-8218, guaranteeing full fitment and compatibility with C-AT 3114, 3116, and 3126 diesel engines[1][3][6][9]. The electromagnetic common rail design confirms the injector’s precision, engineered to deliver optimal atomization required for C-AT 3116 MUI fuel systems and perfectly matched to the 127-8220 injector’s design, ensuring efficient combustion, power output, and emission control[1][3][6]. The listed generic numbers—most notably 0R8467 and 0R8682, with which 127-8220 is directly interchangeable—are widely recognized in the global aftermarket, as all belong to the same fuel injector group for C-AT 3114, 3116, 3126 engines, simplifying replacement sourcing for parts suppliers and field technicians[1][6][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[3][5][6][9].
