Sourcing teams working on high-hour Cummins QSK platforms rely on precise part identification, and injector Y431K05246 is cross-referenced to 4089972, 4928104, FO0BJ60578 and F0OBLOJ014 to simplify verification across supplier catalogs. Engineered for the Cummins QSK19-Series inline 6-cylinder 19-liter diesel engine, and also listed for QSK38 and QSK60 units, this common rail injector supports demanding duty cycles in power generation, mining, marine, rail and oilfield service.
Operating within the Modular Common Rail Fuel System (MCRS), the unit delivers high-pressure fuel with accurate metering and stable atomization. When correctly matched and installed, it supports cylinder balance, reduced smoke, improved starting and restored engine power. It addresses common injector-related symptoms such as hard starting, rough idle, black or white smoke, misfire, low power, high fuel consumption, excessive return fuel and injector fault codes.
Recommended service practice includes return flow testing, rail pressure testing, ECM scanning, injector electrical inspection, cylinder cut-out testing and nozzle inspection, supported by clean diesel fuel and regular filter replacement. For high-hour QSK engines, matched-set testing or replacement reduces repeat downtime and cylinder imbalance. Supplied in sealed packaging with nozzle protection, this injector suits diesel repair shops, engine rebuilders, generator service companies, mining fleets and heavy equipment parts distributors for global B2B export.
