Heavy-duty 24V starter motor identified by primary part number 4297448. The exact user-owned unit label identifies part number 4297448 and 24V. Independent exact-number records consistently identify it as a heavy-duty starting motor for Cummins NT855/NTA855, K19, K38, K50 and related QSK engine families. Public catalogues conflict between 9kW and 11kW, so rated power is deliberately withheld rather than guessed. Confirm the complete 4297448 number, 24V system, mounting flange, pinion, solenoid and terminal layout, plus the engine CPL and serial range before ordering.
Send the machine model, engine model or nameplate photo so our team can confirm compatibility before shipment.
