Product Number: 33407N
The WAI 33407N is a brand-new 12V 4.2kW starter motor. It is manufactured by Letrika (Iskra design), built to replace original-equipment units across a broad range of Ford, Case, Ingersoll Rand, J.C. Bamford and Barber Greene plant and agricultural machines — 57 verified applications in total. It is the direct WAI replacement for LUCAS references 26147, 26189 and 26364, as well as Iskra / Letrika and Mahle equivalents, making it straightforward to identify against an existing part number.
The unit runs at 12 volts with a 4.2kW output, clockwise rotation and a 10-tooth pinion, matching the original specification without modification. Being supplied brand new, there is no core exchange or remanufacturing variability to contend with — the motor leaves the box ready to fit.
