Product Number: 33412N
The WAI 33412N is a brand-new 12V 4.2kW starter motor. It is manufactured by Letrika, designed to the original Iskra specification. It is built to replace worn or failed OE units across 9 Claas Ares applications from the 2003–2005 production window, including the Ares 546, 556, 566, 616 and 656 series. Cross-referenced against Iskra / Letrika numbers 11131191, IS1070 and AZF4562, as well as Mahle MS 110 and MS110, this unit matches the original-equipment specification precisely and installs without modification.
Clockwise rotation and a 10-tooth pinion geometry match the factory ring-gear engagement, ensuring reliable cranking from the moment of fitment. As a brand-new component — not a remanufactured or reconditioned unit — it carries no prior wear, which matters when replacing a starter on a working tractor that cannot afford unexpected downtime.
The starter is also cross-referenced to Letrika 11.131.191, Claas 7700067836, Farcom 105327, and Pasco S920558, giving workshop technicians multiple catalogue routes to confirm suitability before ordering.
