The 320-0688 fuel injector is engineered specifically for the C6 Series diesel engines, including the C6.4 and C6.6 models. As a genuine OE part carrying the 3200688 designation, it is precision-manufactured using high-strength steel and tight-tolerance machining to ensure exact fitment and reliable performance within the original engine architecture. The injector delivers a consistent fuel spray pattern, supporting efficient combustion and stable power output across a wide range of heavy-duty operating conditions.
Built to withstand demanding industrial environments, this injector features anti-corrosion surface treatment and a high-pressure resistant internal structure rated up to 2200 bar. The precision-engineered nozzle and plunger assembly, combined with OEM-standard sealing and spring components, provides long service life and reduced risk of leakage or failure. It operates reliably within a temperature range of -40°C to 120°C, making it suitable for use in construction machinery, agricultural equipment, power generation sets, compressors, and medium-duty marine applications.
Installation follows standard OEM procedures, with recommended mounting torque between 30-35 Nm. Operators are advised to inspect the nozzle for clogging every 500 operating hours, use only clean filtered diesel, and replace injector seals annually. The cross reference number 10R-7220 confirms interchangeability with equivalent units, allowing flexibility in fleet maintenance while preserving the performance integrity of C6.4 and C6.6 engines.
