Engineered as a direct OEM replacement, the 961-4357 fuel injector assembly is specifically designed for Caterpillar 3500 series diesel engines, including the 3512A, 3512B, 3508, 3508B, 3516, 3516B, and 3516C models. Built from heat-treated alloy steel with precision-grade machining, each injector is factory calibrated and 100% performance tested to meet strict OEM specification standards, ensuring reliable fitment, consistent high-pressure fuel delivery, and stable combustion efficiency across demanding heavy-duty operating environments.

This injector serves a broad range of global industrial applications, including generator sets, marine propulsion systems, mining trucks, drilling rigs, oilfield power units, construction machinery, offshore platforms, rail power systems, and utility power stations. The heavy-duty design delivers high temperature resistance, corrosion resistance, optimized fuel consumption, and low emissions performance, contributing to extended service life, reduced fuel dilution risks, and minimized unplanned downtime for fleet operators, shipyards, mining contractors, and power generation facilities.

Routine maintenance supports long-term reliability and includes using clean diesel fuel, replacing fuel filters at recommended intervals, monitoring injector balance rates, avoiding fuel contamination, and performing periodic engine diagnostics. Compatible with cross references 0R-8479, 10R-0957, 211-3028, 217-2570, CAT9614357, 3512B, 3508B, 3516B, and 3516C, the 961-4357 injector is available in brand new or remanufactured options, backed by a 12-month warranty and export-standard packaging for worldwide B2B distribution.
