Perkins original  170-5252 Fuel Injector for C12 C10 Engine 203-3464 229-5918 0R-4987 187-6549 Excavator Aftermarket Parts original new injector

Engineered as a direct OE replacement, the 170-5252 fuel injector is designed to meet the demanding requirements of the Perkins C12 diesel engine platform. Manufactured according to original equipment specifications, this injector ensures accurate fuel atomization, optimal combustion efficiency, lower exhaust emissions, improved fuel economy, and maximum engine performance across heavy-duty trucking, construction equipment, marine propulsion systems, power generation units, and mining machinery applications. Authorized cross references include 10R-0955, 0R-8479, and CAT1705252.

The injector assembly features precision-engineered internal components that deliver consistent and stable injection pressure under all operating conditions. Constructed from high-durability materials with excellent corrosion resistance, it provides long service life even in the harshest industrial and marine environments. The advanced nozzle geometry enhances atomization efficiency, promoting complete fuel burn and reducing soot accumulation within the combustion chamber. OEM fit and function are guaranteed through strict dimensional control and quality verification during manufacturing.

Installation requires cleaning the injector bore thoroughly, inspecting all fuel lines, and replacing sealing components before fitting the new unit. Correct torque specifications must be applied, followed by a complete fuel system bleeding procedure and a diagnostic verification to confirm proper injector operation. Operators should use high-quality diesel fuel, replace fuel filters at recommended intervals, monitor fuel pressure regularly, avoid contaminated fuel sources, and follow standard Perkins maintenance schedules to maximize injector lifespan. Common fault symptoms such as black smoke, white smoke, loss of power, and hard starting can often be traced back to injector nozzle wear, poor atomization, restricted flow, or solenoid malfunction, making timely replacement essential.
