The official Cummins storefront identifies 4984042 as a Cummins starting motor, and five independently reachable exact-number pages passed live revalidation. Repeated exact-number application records support a 24V, 10-tooth starter for Cummins ISDe and ISBe engine families, with additional exact-number listings for ISDe6.7 and QSB6.7. Five owned photographs show one consistent starter, three mounting holes and the matching 10-tooth pinion geometry. Published power ratings conflict between 5.5kW, 6.0kW and one 8kW headline, so power is intentionally omitted from the verified specification rather than guessed. Confirm 4984042, voltage, tooth count, flange, rotation, terminals and engine serial before shipment.
Send the machine model, engine model or nameplate photo so our team can confirm compatibility before shipment.
