In this video, we demonstrate the QDJ2403P starter motor for Nissan FD46 diesel coach and bus applications. Watch a step-by-step bench test, close-up inspection of the 11-tooth pinion and mounting flange, and a direct comparison against OE references 233000T003, 233000T005, M002T78682, M2T78681, and STM3866. We show the practical steps and results so you can judge suitability quickly.
