The Perkins 10R-4764 fuel injector is an OEM-specification electronic unit injector engineered for the Perkins C9 and C9 ACERT diesel engine platforms. Manufactured with precision-machined internal components and OEM-calibrated fuel metering geometry, this injector delivers consistent high-pressure injection for reliable combustion across demanding duty cycles found in construction, mining, power generation, marine, and heavy-duty transportation equipment.

Built for industrial reliability, the 10R-4764 incorporates advanced atomization technology, corrosion-resistant construction, and tightly controlled spray patterns to improve combustion efficiency, enhance engine power output, and reduce fuel consumption along with smoke emissions. The robust assembly supports extended piston and cylinder service life while improving cold-start performance under varying environmental and load conditions, ensuring stable engine performance in excavators, wheel loaders, articulated trucks, diesel generator sets, commercial vessels, and vocational heavy equipment.

Routine maintenance practices help maximize injector longevity, including the use of high-quality ultra-low sulfur diesel that meets Perkins specifications, regular replacement of fuel filters, prevention of water contamination, monitoring of fuel rail pressure, and periodic injector diagnostics such as balance testing, ECM fault code verification, return flow measurement, and cylinder cutout testing. Authorized cross reference numbers 254-4339 and 387-9433 support flexible identification and interchange across the Perkins C9 engine family.
