Caterpillar original Wholesale Diesel Engine Spare Part 0R-8475 Fuel System Component Replacement for Repair Shops Importers and Distributors original new injector

The Caterpillar 0R-8475 Cat Reman fuel injector is engineered as a direct replacement unit for the CAT 3116 inline-six diesel engine and the CAT 3114 engine family, covering applications such as the CB-434 and CS-531 vibratory compactors. Built to Cat Reman remanufactured standards, the injector features a 7mm body with a 0.195 orifice, providing accurate diesel fuel metering, stable high-pressure injection, and a clean atomized spray pattern that supports balanced cylinder performance across the 6.6L platform.

Designed for heavy-duty industrial, road construction, and engine-rebuild service environments, this unit injector delivers reliable combustion control and supports consistent engine starting, idle quality, and fuel economy on aging high-hour engines. It can be ordered as a single replacement or as a complete matched six-cylinder set for full engine refurbishment. Related service components include the 6V-6228 O-ring, 119-2940 gasket, 119-3061 injector sleeve, 032-8970 FKM O-ring, and 1R-0750 secondary fuel filter, allowing a complete injector service with approved sealing and filtration hardware.

Routine maintenance of the 0R-8475 injector depends on clean fuel, proper filtration, regular water-separator draining, correct installation torque, and inspection of the injector sleeve and seals at every removal. Operators should monitor exhaust smoke, fuel consumption per machine hour, and engine oil for fuel dilution, using fuel pressure testing, cylinder balance testing, and injector synchronization to confirm diagnosis. When multiple injectors show wear-related symptoms on high-hour engines, replacing all six injectors as a matched set helps maintain engine balance and long-term reliability.
