Engineered for correct fitment on the Cummins QSK19 platform, injector Y431K05429 targets professional rebuilders and service fleets that need dependable high-pressure fuel delivery. This unit crosses to 0986435903 and 4964170, and supplier listings also cover QSK38 and QSK60 series work, supporting the Modular Common Rail Fuel System used across these 19 L in-line six-cylinder engines with 159 mm x 159 mm bore and stroke.
When correctly matched and installed, this common rail injector supports accurate metering, stable atomization, cylinder balance, reduced smoke, better starting and restored power on high-hour QSK engines. It suits generator sets rated 500–550 kW prime and 550–600 kW standby, mining power units, crushing plants, oilfield pump drives, rail power units, marine auxiliary engines and construction machinery. Typical buyers include diesel repair shops, generator service companies, mining fleets, engine rebuilders and parts distributors.
To protect performance, use clean diesel fuel, replace fuel filters, drain water separators and prevent tank contamination. During service, check ECM fault codes, return flow, rail pressure, cylinder contribution and electrical connectors. For high-hour engines, matched-set testing reduces repeat downtime. Final fitment must be confirmed by engine serial number, CPL, ECM model and old injector number before shipment.
