Product Number: 19155N
The WAI 19155N is a brand-new 12V 3.1kW direct-drive starter motor. It is manufactured by Letrika (Iskra DD), supplied as a direct replacement for original-equipment units referenced under Case 138207A1, Mahle MS 355, and the Iskra / Letrika family including AZJ3243, IS0705, and 11130705. It is built to OE specification and suited to agricultural and plant machinery applications where these references are called out.
This starter delivers 3.1kW of cranking power at 12 volts with clockwise rotation and an 11-tooth pinion, matching the geometry and electrical characteristics of the original Letrika direct-drive unit it replaces. The brand-new condition means no worn commutators, no reground armatures, and no uncertainty about service life — it leaves the box ready to fit.
The Letrika (Iskra) DD design is well established across agricultural and industrial plant equipment. WAI, as a specialist in rotating electrics, supplies this unit to the same dimensional and electrical specification as the original, covering 5 OE cross-references across the Case, Mahle, and Iskra / Letrika catalogues.

The best way to find the correct starter motor is to combine the machine and engine details with the OEM or original starter reference, then confirm voltage, rotation, pinion teeth, mounting and terminal position. Do not choose a replacement from appearance alone.
A starter motor usually clicks without cranking because the battery cannot deliver enough current, resistance is present in the battery cables or engine ground, or the starter control circuit and solenoid are not operating correctly. A click does not automatically mean the...
