Product Number: MS399
The WAI MS399 is a 12V 3.2kW PLGR-design starter motor. It is manufactured by MAHLE, supplied brand new and intended as a direct replacement for the LETRIKA (ISKRA) original-equipment unit 11.131.781. It is engineered for the demanding duty cycles found in plant and agricultural machinery across a broad spread of manufacturers and model lines.
The MS399 delivers 3.2kW of cranking power through a clockwise-rotating, 10-tooth drive pinion — the configuration demanded by the Perkins, Massey Ferguson, JCB, Bobcat, Manitou, Farmtrac, and Hidromek machines it is listed to fit. The PLGR (Permanent Magnet Gear Reduction) architecture uses a permanent-magnet field assembly feeding through an internal gear-reduction stage, producing high torque at relatively low current draw — a characteristic that eases the electrical load on ageing wiring harnesses and batteries in older plant and farm equipment.
In total, fitment data covers 52 applications spanning seven makes, with particularly strong coverage across Manitou (21 applications) and Bobcat (15 applications), including the Bobcat T35100, T35120, T2256, T2566 telehandler and tracked loader ranges built between 2004 and 2009.
