Product Number: 33410N
The WAI 33410N is a brand-new 12V 4.2kW starter motor. It is manufactured by Letrika (Iskra design), built as a direct OE replacement for Remy 19083050, Iskra and Letrika original-equipment units across a wide range of agricultural and industrial machinery. With 44 verified cross-references on file, this unit replaces Remy, Iskra, Mahle, Letrika, Agco and Alpina originals — including the high-demand references Agco 3823 621 M91, Agco 3823 621 M96 and Alpina 3823621M91.
Clockwise rotation and a 10-tooth pinion ensure correct engagement with the ring gear on compatible engines, while the 4.2kW output delivers the cranking power demanded by larger agricultural powerplants. Supplied brand new — not remanufactured — it meets original Letrika specification throughout.
Fitment covers 85 confirmed applications, with 81 Massey Ferguson models (including the MF-3655, MF-4435, MF-4455, MF-5465 and MF-5470), two New Holland Industrial machines and two Perkins engine-based applications. Always verify your engine variant and frame number against the full catalogue before ordering.
