The Perkins C9 HEUI fuel injector bearing OE number 266-4446 is engineered as a direct OEM replacement for the Perkins C9 and C9 ACERT diesel engine platforms. It cross-references with 236-0962, 235-2888, 217-2570, 188-8739, 10R-7224, 20R-8063, 387-9434, 328-2573, 293-4071, and 267-9734, providing a reliable interchange solution for inventory consolidation and aftermarket replacement across multiple equipment lines including excavators 330C, 330C L, and 973C, track type tractors D6R, D6R II, and D6T, wheel loaders 627G and 637G, and motor graders such as the 160M.
Manufactured from hardened alloy steel with precision-ground valve assemblies and high-performance nozzle technology, this electronically actuated unit injector delivers injection pressures above 23,000 PSI (1,600 Bar). The HEUI design integrates hydraulic actuation with electronic ECM control, ensuring optimized fuel atomization, stable combustion, and consistent power output while supporting emissions compliance over extended service intervals. Each unit is factory calibrated and tested to meet OEM performance standards.
During installation, technicians should clean the injector bore, install new sealing washers, lubricate O-rings with clean diesel fuel, and conduct a leak-off test after fitting. To preserve long-term performance, operators should use ultra-clean diesel, replace fuel filters on schedule, avoid water contamination, monitor fuel pressure, and verify return flow rates along with ECM calibration parameters.
