Perkins original  20R-3247 Common Rail Fuel Injector Assembly for 3516C 3512C 3512B 3516B C35 3508B Excavator Replacement for OEM  original new injector

The Perkins 3512B Fuel Injector 20R-3247 is an OEM-quality remanufactured injector assembly engineered for the Perkins 3500 Series diesel engines, including the 3512B, 3512C, 3512B Marine, and Perkins 3512 Generator Engine configurations. With a 51.8-liter V12 displacement platform, this injector delivers precision fuel atomization and stable combustion across continuous-duty power generation, marine propulsion, mining, oil and gas, and heavy construction equipment applications. Each unit is produced to industrial-grade manufacturing standards, ensuring high durability construction and extended operating life under demanding operational loads.

This reman injector assembly is designed as a direct replacement for OE numbers 20R3247, 236-9007, 2369007, 10R-7075, and 10R7075, and is fully compatible with the Perkins fuel system architecture. The injector improves combustion efficiency, increases engine power output, reduces fuel consumption, and lowers particulate emissions. Enhanced engine response and improved reliability make it a dependable solution for reducing downtime in continuous-duty generator sets and emergency backup power systems operating in harsh industrial and marine environments.

Proper installation and maintenance are essential for optimal injector performance. Before installation, operators should clean the injector bore thoroughly, inspect fuel lines, replace sealing components, verify injector seat condition, and follow Perkins service procedures, followed by a post-installation leak inspection. Best maintenance practices include using clean diesel fuel, replacing fuel filters regularly, monitoring exhaust smoke levels, performing periodic injector testing, avoiding water contamination, and maintaining proper fuel pressure to prevent excessive exhaust smoke, engine knock, cylinder imbalance, fuel leakage, reduced power output, increased fuel consumption, difficult starting, and unstable idle.
