Starter motor identified by model QDJ1409B-P and published reference 1173240KZ. Exact-model records specify 12V, 3.8kW, a 9-tooth pinion and a three-bolt mounting flange, with applications for Deutz F2L912, F3L912, F4L912 and F6L912 engines. Five exact owned photographs show one consistent starter; the visible product label also reads QDJ1409B-P and 12V 3.8kW. Similar 912-series starters can differ in drive, rotation, flange and terminal layout, so additional catalog numbers seen in broad marketplace lists are not presented as direct interchanges. Confirm the old unit number, pinion teeth, mounting dimensions, rotation, terminals and engine variant before ordering.
