Caterpillar original 7E-6193 0R-8461 162-0218 Mechanical Fuel Injector 105-1694 for 3116 Engine 320B 322B Excavator Injection Valves 7E6193 new original new injector

The Caterpillar 7E-6193 mechanical fuel injector is engineered for CAT 3116 series diesel engines, with supplier-listed coverage extending to 3114 engine applications. Built to OE-style fitment standards, it delivers a controlled quantity of pressurized diesel fuel into the combustion chamber at the correct timing and in the correct spray pattern, converting that fuel into a fine atomized mist for efficient combustion. Heavy-duty internal construction supports accurate fuel delivery, strong atomization, consistent flow rates, and controlled leakage performance across demanding industrial duty cycles.

This injector carries a wide interchange coverage across the 3116 injector family, including cross references 0R-8473, 0R-8461, 4P-2995, 7E-8727, 0R-8470, 7E-8951, 0R-3388, 127-8220, 140-8413, 9Y-4982, 101-4561, 127-8205, 101-8673, 127-8207, 102-7038, 127-8209, 102-7732, 127-8213, 102-7734, 127-8216, 105-1694, 127-8218, 107-7733, 107-7773, 127-8222, 107-1230, 127-8225, 127-8211, 127-8228, 4P-2233, 127-8230, 4W-6017, 7C-4567, 162-0212, 7E-7607, 162-0218, 173-4647, 10R-8996, 7E-8729, 7E-8952, 0R-0471, 0R-3389, 0R-3580, 0R-4374, 0R-8477, and 0R-8479. It is suitable for medium-duty trucks, excavators, wheel loaders, generator sets, industrial pump sets, marine auxiliary engines, construction machinery, mining support equipment, agricultural machinery, and stationary industrial diesel power units, serving distributors, repair shops, fleet operators, and diesel engine service companies across global markets.

To maximize service life, use clean diesel fuel, maintain fuel filtration, drain the water separator regularly, inspect for external leakage, monitor exhaust smoke, check idle quality, and test return flow when required. Before installation, verify the part number, engine model, serial number, and original injector marking, clean the injector bore, replace sealing components, torque according to the OEM service manual, bleed the fuel system, and confirm idle, acceleration, and warm-up performance.
