C-ATerpillar 3116 Series Fuel Injector 127-8222

A high-performance, OEM-standard fuel injector exclusively engineered for C-ATerpillar 3114, 3116, and 3126 diesel engines, the 127-8222 integrates precision craftsmanship, durable anti-rust materials, and comprehensive after-sales support to meet the harsh operating demands of C-ATerpillar excavators, wheel loaders, tractors, combine harvesters, and industrial power units equipped with the 3116 engine platform. Adhering to strict OEM specifiC-ATions, with ISO certifiC-ATion and stable global supply capacity (up to 5000 pieces per year), 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 127-8222 fuel injector, a critical replacement component engineered specifically for C-ATerpillar 3114, 3116, and 3126 diesel engines. Available as genuine C-AT, C-AT reman, or premium aftermarket variants from trusted suppliers, it adheres to strict OEM specifiC-ATions (ISO certified) and is directly interchangeable with 0R8461, 4P1731, 4P-1731, 1071230, and 20R-2051, guaranteeing seamless fitment across a wide range of C-ATerpillar equipment—from 325 excavators and 950F wheel loaders to Challenger tractors and 460 combines[2][3][8][10]. As an 8mm plunger size mechanical injector or electromagnetic common rail injector with coated plungers, it delivers precise fuel atomization and delivery, critical for optimizing engine efficiency, power, and wear resistance—key requirements for heavy-duty equipment used in construction, agriculture, and industrial appliC-ATions[2][7]. Constructed from high-strength alloy steel with precision internal components and a 7-orifice nozzle tip, it is built to withstand harsh operating conditions, ensuring long service life and resistance to corrosion[2][7][9]. 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 127-8222 (with OEM numbers 1278222 and CA1278222), it maintains the performance standards required for C-AT 3116 engines, reducing unplanned downtime, with in-stock availability (3-5 working days delivery) and stable supply (up to 5000 pieces per year) to meet global demand[1][2][5][7].

2. Physical Dimensions & Volume (Focus on Appearance)

The 127-8222 injector features a rugged, compact physical design specifically optimized for the tight engine compartments of various C-AT equipment powered by 3116 engines—from 325 excavators and 950F wheel loaders to Challenger tractors and 460 combines—balancing durability with space efficiency and adhering to original OEM size specifiC-ATions for the 127-8222 model[2][7][10]. Its solid high-strength alloy steel profile, with coated plungers, withstands severe vibration, high pressure, and mechanical stress during heavy-duty operation, critical for equipment used in construction, agriculture, and industrial appliC-ATions where harsh conditions are common[2][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 agricultural environments. The polished metal nozzle tip, precision-machined with a 7-orifice design to match C-AT 3116 atomization requirements, maintains dimensional precision and resists clogging, ensuring consistent fuel delivery under high pressure for both mechanical and electromagnetic variants[7][9]. With a net weight of 0.5 kg (1.10 lbs), it balances robustness and ease of handling during installation and replacement, suitable for professional maintenance teams. The weather-resistant electromagnetic connector bracket (for applicable variants) ensures reliable 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[7][10]. The flexible packaging configuration (neutral, original, or bulk options, including wooden pallets) 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][7][9].

3. Cross Reference & Generic Numbers

This table provides comprehensive cross-reference and generic number data for the 127-8222 injector, a critical resource for global parts identifiC-ATion, ordering, and replacement, adhering to industry aftermarket cross-reference standards. The primary original part number, 127-8222, directly corresponds to C-ATerpillar’s original equipment numbers (1278222, CA1278222, CA20R-2051) and is fully interchangeable with 0R8461, 4P1731, 4P-1731, 1071230, 20R-2051, and 127-8216, guaranteeing full fitment and compatibility with C-AT 3114, 3116, and 3126 diesel engines[3][8][10]. The dual-type design (mechanical 8mm plunger or electromagnetic common rail) confirms the injector’s versatility, engineered to deliver optimal atomization required for C-AT 3116 fuel systems and perfectly matched to the 127-8222 injector’s design, ensuring efficient combustion, power output, and emission control[2][7]. The listed generic numbers—most notably 0R8461 and 4P1731, with which 127-8222 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][3][8][10]. 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 325 excavators and 950F wheel loaders[2][3][10].
