The Caterpillar CAT 557-7627 fuel injector (also written 5577627) is a heavy-duty diesel injector built for Caterpillar engine fuel systems, where accurate fuel metering, stable injection, clean atomization, and efficient combustion directly affect machine uptime and fuel cost. It is cataloged mainly around CAT C7 and C7 ACERT diesel engines and is also widely listed for C9 and C9.3 applications across construction and industrial equipment.
For sourcing and cross-reference, 557-7627 is the main confirmed part number, and 20R-9079 / 20R9079 is the confirmed Cat Reman alternative shown in the public Cat parts channel. Frequently listed interchange numbers include 387-9427 / 3879427, 10R-7225 / 10R7225, 20R-8066 / 20R8066, 268-1835 / 2681835, 295-1411 / 2951411, and 328-3585 / 3283585, plus aftermarket references 713431AT, CA5577627, and CA3879427. Buyers should use 557-7627 and 20R-9079 as the strongest verification numbers.
Typical applications cover Caterpillar excavators 324D, 325D, 326D L, 328D LCR, and 329D; wheel loaders 950H, 962H, 966D, 966E, and 966F; and motor graders 12K, 12M, 120K, 140K, 140M, and 160K, along with material handlers, skidders, asphalt pavers, and industrial or petroleum engines. Because Caterpillar fuel systems vary by arrangement and serial number, final fitment should be confirmed against the engine serial number, machine serial number, and original injector tag before ordering; send your serial details for a fast compatibility check and quotation.
