This original-type, new injector is offered for heavy-duty fuel-injection repair and replacement, with the formatted Bosch references 0 986 435 912 and 0-986-435-912 supporting catalog and inquiry matching.

Public cross-reference data strongly associates the injector with 4964172 and 4955526, including their NX, PX, RX and KX variants, as well as F00BL0J013 and F00BL0J014.

QSK19 and QSK60 appear in supplier search groups, but these references alone do not confirm universal fitment; QSK19 inquiries, in particular, should be checked against the engine configuration before sale.

Potential equipment coverage includes generator sets, mining equipment, excavators, construction machinery, marine engines, oil and gas equipment, rail-related equipment, industrial power units and agricultural pump sets. Buyers should provide the engine serial number, CPL, original injector number and tag photo, relevant reference numbers, engine and machine models, fuel-system and ECM details, condition requirement, quantity and destination country. Verification against the correct fuel-system version helps reduce wrong-fitment risk for distributors, rebuilders and maintenance buyers.
