443-9454: Caterpillar Fuel Injector 443-9454 | New Part No. for 20R-5566 – CAT C175-16/C175-20 CR Injector

This CR1100 common rail fuel injector is a high-quality aftermarket replacement for Caterpillar C175-16 and C175-20 mining diesel engines. It replaces OE part number 443-9454, the new part number for Cat Reman 20R-5566. Each injector is built to OEM specification with a precision-machined nozzle and hardened internals, delivering accurate injection timing, atomization and metering at extreme common rail pressure for stable combustion, full rated power and fuel economy under continuous heavy-load operation. High-grade steel components and hardened valve seats withstand the extreme thermal and mechanical loads of ultra-class mining engines, with sealing surfaces and electrical connections matching the original design for a leak-free, bolt-on fit. Every injector is flow- and leak-tested before shipment. Fits Caterpillar ultra-class mining haul trucks (797F, 797, 793F, 794 AC, 795F XQ, 795F AC, 797B, 798 AC) powered by C175-16/C175-20 engines. Export-packed, 12-month warranty and responsive technical support. Aftermarket replacement part — not a genuine Caterpillar product.
