Perkins original  Diesel Fuel Injector 20R-3247 392-0225 20R-1269 Common Rail for 3516B 3512B Excavator 3508B Engine Parts  original new injector

The Perkins 3512B 3512C Fuel Injector is identified by the primary OE number 20R-3247, with the cross references 236-9007 and 10R-7075 ensuring broad interchangeability across the Perkins 3500 series engine platform. Built to OEM quality standards, this remanufactured injector assembly is engineered for the V12, 51.8-liter diesel configuration found in the Perkins 3512B and Perkins 3512C power units. It serves demanding applications including continuous duty generator sets, marine propulsion systems, mining haul trucks and excavators, oil and gas field equipment, and heavy construction machinery operating in remote or harsh environments.

Manufactured with industrial grade components and precision-machined nozzle assemblies, this 20R-3247 injector delivers stable fuel atomization, improved combustion efficiency, and consistent engine response under heavy load conditions. Operators benefit from increased power output, reduced fuel consumption, lower particulate emissions, and extended operating intervals, all of which contribute to reduced downtime and lower total cost of ownership. Each unit is designed for direct compatibility with Perkins fuel systems, providing a reliable replacement solution for the 236-9007 and 10R-7075 part numbers in field service, scheduled overhaul, and emergency rebuild scenarios.

Proper installation requires thorough cleaning of the injector bore, inspection of fuel lines, replacement of all sealing components, and verification of injector seat condition, followed by a post-installation leak check in accordance with Perkins service procedures. For sustained performance, use clean diesel fuel, replace fuel filters at recommended intervals, monitor exhaust smoke levels, conduct periodic injector testing, avoid water contamination, and maintain proper fuel system pressure. This proactive maintenance approach helps prevent common symptoms such as excessive exhaust smoke, engine knock, cylinder imbalance, fuel leakage, reduced power output, increased fuel consumption, difficult starting, and unstable idle, ensuring long-term reliability of the Perkins 3512B and 3512C engine fleet.
