476-8769: Caterpillar Hydraulic Injector Pump Group 476-8769 | HEUI Actuating Pump for CAT C9 – Fits 586C 637G D6R

This hydraulic injector pump group (HEUI actuating pump, 12-volt basic) is a high-quality replacement for Caterpillar C9 HEUI fuel injection systems. It replaces OE part number 476-8769, cross-referenced to the remanufactured number 20R-1636 and 384-0678. The pump builds and maintains the high oil pressure required to actuate HEUI unit injectors, delivering precise injection timing and metering for reliable starting, stable idle and full rated power. Hardened pumping gears and precision-machined housing stand up to sustained high-pressure operation, with OEM-spec mounting and sealing surfaces for a leak-free, bolt-on fit. Every unit is bench-tested for pressure and flow before shipment. Fits Caterpillar scrapers (586C, 637E, 637G, 637D), track-type tractors (D6R III, D7R), compactors (814F, 815F, 816F), generator sets (D250GC, D300GC) and hydraulic excavators (330D, 336D). Export-packed, 12-month warranty and responsive technical support. Aftermarket replacement part — not a genuine Caterpillar product.
