Product Number: 18422N
The WAI 18422N is a brand-new 12V 3.4kW starter motor. It is built to the Letrika (Iskra) PLGR design, supplied as a direct OE-quality replacement for units originally referenced under Valeo 436 070, Iskra AZF4284 and AZF4521, Mahle Original MS89, Prestolite Electric 35259580, Letrika 11.131.374, and a further 65 cross-referenced part numbers across leading aftermarket and OE catalogues. It is engineered to match the original specification precisely, making it a reliable choice when an ageing starter is reluctant to turn over or has failed outright.
With clockwise rotation, a 10-tooth pinion and a rated output of 3.4kW at 12V, the WAI 18422N delivers the cranking torque and engagement geometry the original equipment demands. The PLGR (Permanent Magnet Gear Reduction) design is known for compact dimensions and efficient power delivery — qualities that make it well suited to the industrial and agricultural plant machinery it serves.
The motor covers 53 confirmed applications across John Deere, Compac Equipment Mfg., Ingersoll Rand, Bobcat, and Clark machines. John Deere fitment alone accounts for 40 applications, with OE references John Deere AJ59342 and AL110503 listed in the cross-reference data. Compac Equipment Mfg. T-series compact tractors from 1997–2000 also feature prominently in the application list.
