The Perkins 3116 3126 fuel injector, OE 10R-8996 and cross-referenced as 173-4647, is engineered as a direct replacement for the 3116 inline 6-cylinder diesel engine and the 3126 marine and industrial engine platforms. With a displacement of 6.6 L and turbocharged-aftercooled aspiration producing outputs up to 350 bhp at 2800 rpm, these engines depend on precise fuel metering for reliable combustion under heavy-duty operating conditions.
Manufactured to Perkins® Reman standards, this injector GP-fuel delivers consistent flow performance, OE-style fitment, and heavy-duty construction suitable for medium-duty truck repair, construction machinery service, marine engine maintenance, industrial engine rebuilds, generator repair, and fleet maintenance programs. Approximate physical dimensions of 8.8 in length and 4.8 in height ensure proper installation within the original injector bore. The global cross-reference recognition through numbers 10R-8996, 10R8996, 173-4647, and 1734647 simplifies sourcing across North America, South America, Europe, the Middle East, Africa, Southeast Asia, and Australia.
Proper maintenance extends injector service life: operators should replace fuel filters on schedule, use clean diesel, drain the water separator regularly, maintain the air intake system, keep engine oil clean, avoid mixing injectors of different calibration levels, store injectors in sealed packaging, and install them only in a clean repair environment. Common failure symptoms such as hard starting, rough idle, white or black smoke, engine knock, power loss, high fuel consumption, fuel dilution, misfire, and high exhaust temperature can be addressed through systematic diagnostics including fuel pressure, fuel return, cylinder balance, injector sealing, filter condition, air intake restriction, turbocharger performance, and injector calibration checks.
