QDJ254 is a 24V, 4.5kW gear-reduction starter with an 11-tooth pinion and three-bolt mounting for Yuchai 4108 applications. A manufacturer product list records QDJ1408V as the paired model and Foton 4108Q as the application. Independent exact-model technical tables confirm 24V, 4.5kW, three mounting points and 11 teeth. QDJ2692 is not included because no reliable relationship to QDJ254 was found. Confirm the original model label, flange, pinion and engine serial range before shipment.
