original 418-8820 162-0218 127-8228 127-8230 162-0212 Diesel Engine Fuel Injector for Excavator Marine original new injector

Engineered specifically for the 3116 Series diesel engine, the 418-8820 / 4188820 unit injection pump group delivers OE-style fitment, precision fuel metering, and reliable high-pressure injection performance. The assembly receives fuel from the supply circuit, meters the correct quantity per cycle, builds injection pressure internally, and atomizes the fuel directly into the combustion chamber at the correct timing before sealing the circuit and resetting. This integrated design supports stable combustion, consistent power output, and efficient fuel economy for engine rebuilders, diesel repair shops, machinery owners, and parts distributors.

The injector is listed with an extensive cross-reference database, including 20R-4179, 224-9090, 184-2527, 137-4729, 7E-5645, 7C-3854, 6I-4401, 20R-1923, 10R-1252, 0R-8575, 0R-3815, 0R-6130, 0R-5510, and 0R-0471, making it easy to locate when sourcing replacements for heavy-duty equipment, generator sets, and industrial power applications. Strong database searchability ensures the part can be quickly identified through OE numbers, reman numbers, and old numbers. Final compatibility must always be confirmed by existing injector number, engine serial number, engine arrangement number, machine model, and service manual.

Proper service life depends on clean fuel, correct filtration, water separation, careful handling, and correct installation. Fuel contamination is one of the most common causes of diesel injector failure, so regular fuel filter replacement, water separator draining, and tank cleanliness are essential. Common injector-related symptoms include hard starting, long cranking, rough idle, misfire, black smoke, white smoke, knocking, power loss, high fuel consumption, leakage, and high exhaust temperature. A complete diagnosis should also check fuel pressure, fuel pump, compression, timing, turbocharger, and air intake.
