Product Number: MS291
The WAI MS291 is a brand-new 12V 4.2kW PLGR-design starter motor. It is manufactured by MAHLE, replacing the LETRIKA (ISKRA) original-equipment reference 11.131.573. Built to OE specification, it is a direct-fit replacement for a wide range of plant and agricultural machinery, with over 85 confirmed applications spanning Ford, Case, Ingersoll Rand, J.C. Bamford, Barber Greene, and Dennis equipment.
The MS291 delivers 4.2 kilowatts of cranking power from a 12-volt supply through a clockwise-rotating, 10-tooth PLGR pinion — a geometry engineered to engage cleanly and reliably under the demanding cold-start and high-cycle conditions common to plant and farm environments. Being brand new rather than remanufactured, it carries no uncertainty around core wear or previous service history.
With a Lester catalogue number of 33407, the MS291 is straightforward to cross-reference within trade and workshop catalogues. Confirmed fitment includes Ford models (61 applications), Case machines (7 applications), Ingersoll Rand equipment (6 applications), J.C. Bamford plant (5 applications), Barber Greene pavers (4 applications), and Dennis vehicles (2 applications) — use the selection widget or search by OEM number to confirm your specific variant.
