Product Number: 18940N-IK
The WAI 18940N-IK is a brand-new 12V 3.2kW starter motor. It is built to the Letrika (Iskra) PLGR design, supplied as a direct replacement for Perkins original-equipment numbers 2873K405 and 2873K624 — the two most-searched references for this unit. With 75 OE cross-references in total, it also replaces a wide range of Iskra and Letrika part numbers across agricultural, plant, and industrial engine applications.
Engineered to the same PLGR specification as the original Iskra unit, the 18940N-IK delivers 3.2kW of cranking power through a 10-tooth pinion on a 12V system. Brand-new condition means no remanufactured wear risks, and the Letrika (Iskra) PLGR design is a proven, widely fitment-matched architecture across Perkins engine families, JCB telescopic handlers, and Massey Ferguson tractors including the MF-290.
Fitted applications include Perkins 1103C-33, 1103D-33, and 1104D-44 engines (2004–2014), JCB 530 and 540 (2003–2007), and Massey Ferguson MF-290 (1979–1986) — six applications listed from a total fitment base spanning Perkins, JCB, and Massey Ferguson machines. Always verify your engine variant and existing part number before ordering.
