Perkins original Perkins 0R-0471 Mechanical Fuel Injector for 3116 Engine Excavator 320B 325B Replacement for OEM new injector original new injector

The Perkins 3116 Fuel Injector 0R-0471 is a precision-engineered mechanical unit injector designed specifically for the Perkins 3116 inline six-cylinder diesel engine. Manufactured to meet original equipment tolerances, this injector delivers consistent fuel atomization through a multi-hole sacless nozzle, supporting the engine's 205 to 350 HP output range. The mechanical plunger, barrel, and spring assembly operates directly from camshaft motion, providing reliable fuel delivery timing and quantity without reliance on electronic control modules. This robust construction makes it well suited for demanding heavy equipment operations in construction, mining, marine propulsion, and generator set installations.

Featuring hardened nozzle tips and thermal-resistant internal components, the 0R-0471 injector is built for extended service life in harsh industrial environments. Broad cross-reference compatibility with part numbers including 0R-0471, 0R0471, OR0471, 4P-9077, 9Y-4982, 101-4561, 127-8205, 0R-3389, 0R-8467, 0R-8682, 127-8220, 4P-2995, 7E-8952, 105-1694, 7E-8727, 162-0212, and 127-8230 simplifies sourcing for fleet operators and service facilities. Each unit is assembled with precision components that maintain OEM specifications for seating height, pop pressure, and spray pattern consistency.

This injector is compatible with Perkins excavators such as the 200B, 205B, 320B, 322B, and 325B, the 446B backhoe loader, medium-duty trucks, marine engines, and industrial machinery including pumps and compressors. Proper installation following Perkins torque specifications, combined with scheduled fuel system maintenance, ensures optimal engine performance, reduced smoke emissions, and stable idle characteristics throughout the injector's operational life.
