original 245-8272 Diesel Engine Parts Injector 246-1854 229-1631 204-2067 for 3512C new injector original new injector

Engineered specifically for the 3512B engine platform, fuel injector 245-8272 delivers consistent atomization and stable fuel delivery across the full operating range of the 3512B, 3512C, 3516B, 3516C, and 3508 engine series. The injector body is CNC machined to original dimensional tolerances, ensuring a precise fit within the cylinder head bore and reliable seating with the combustion chamber. Hardened alloy steel internal components resist wear under continuous high-load operation, while specialized surface coatings protect against sulfur corrosion, moisture ingress, and thermal degradation common in heavy industrial environments.

This injector assembly is widely deployed in G3512 generator sets, marine propulsion engines such as tug boats and cargo vessels, and high-demand equipment including mining haul trucks, drilling rigs, gas compression units, and offshore platform power systems. Cross-referenced against 125-8272 and 10R-1272, the part supports flexible sourcing for fleet operators managing mixed engine inventories across power generation, oil and gas, and marine sectors. Stable injection quantity promotes balanced cylinder performance and reduces vibration in multi-cylinder configurations.

Prior to installation, operators should clean the cylinder head bore, inspect the injector seat surface, and replace the copper washer and O-rings supplied with the unit. Fuel lines must be flushed and the system bled to specification. Following installation, technicians should verify starting behavior, inspect for leaks, and monitor exhaust characteristics to confirm proper injector function. Routine monitoring of fuel consumption and exhaust color helps identify early-stage wear, supporting preventive maintenance and extended service intervals for 3512B powered equipment.
