original Diesel Engine Fuel Injector 20R-4147 for 3412 3408 3142E Engine Fuel Injector Pump Replacement for OEM 20R-0758 198-6877 232-1168 10R-1266 original new injector

Engineered for demanding industrial environments, the 20R-4147 Fuel Injector delivers reliable fuel atomization and consistent combustion performance across the 3412, 3412B, and 3412C diesel engine series. This precision-manufactured injector supports mechanical and common rail configurations, operating within a pressure range of 1200–1600 bar and providing a controlled spray angle of 150°–160° for uniform fuel distribution. Cross-referenced with OE numbers 10R-7222, 331-8770, and 0R-4171, it offers a versatile replacement solution for global industrial operators seeking OEM-certified quality.

Constructed from high-grade alloy steel, the injector features precision-machined nozzle tips, corrosion-resistant materials, and high wear resistance suited for continuous heavy-duty operation. It is compatible with industrial diesel and biodiesel blends, making it ideal for mining and construction equipment such as earth movers, bulldozers, and excavators; marine applications including tugboats, cargo ships, and fishing vessels; industrial power generation systems like diesel generators and compressors; and heavy equipment such as loaders, graders, and large-scale agricultural machines.

For optimal performance, tighten mounting bolts to 35–40 Nm, pre-lubricate with clean diesel oil before installation, and verify the spray pattern on a diagnostic bench prior to engine fitment. Clean fuel filters regularly, inspect spray patterns and nozzle wear periodically, and replace the injector every 20,000–30,000 operating hours. Backed by a 12-month industrial warranty, this component ensures dependable long-term service.
