Product Number: 17639N
The WAI 17639N is a brand-new 12V 2.7kW starter motor. It is built to the Lucas M45G and 2M113 DD design, replacing original-equipment units from Hitachi (including S12-85 and S12-87), Bosch (including 0 001 362 008 and 0 001 362 049), Delco Remy (DRS3286), Perkins (2873A104), and Iskra / Letrika (including IS0408 and IS0711) — 116 OE cross-references in total. It is a direct-fit replacement for agricultural and plant machinery, covering 45 applications including Massey Ferguson models such as the FE-65, MF-135, MF-148, MF-154, MF-165, and MF-174, the J.C. Bamford 406, and Perkins-engined equipment.
The unit delivers 2.7kW of cranking power at 12V with clockwise rotation and a 10-tooth pinion — parameters matched to the Lucas M45G pre-engaged design — so it integrates directly with the original starter circuit without modification. As a brand-new part (not a remanufactured exchange unit), there is no core charge and no uncertainty about the condition of internal components.
With 116 OE cross-references spanning Hitachi, Bosch, Delco Remy, Perkins, and Iskra / Letrika, the 17639N is one of the most broadly cross-referenced starters in the WAI range for this application family, making it straightforward to source whether you are working from a machine model, an OE part number, or an old Lucas reference.
