Product Number: 18051N
The WAI 18051N is a brand-new 12V 2.0kW starter motor. It is built to Hitachi OSGR specification, replacing original-equipment units across Hitachi, Yanmar, Delco Remy, Isuzu, and Mustang references — including Hitachi S13-124, S13-132, and S13-294, and Yanmar 12913677011. It is suited to compact plant machinery and agricultural equipment where a reliable, direct-replacement starter is required.
Constructed to OSGR (Off-Set Gear Reduction) design principles, this unit delivers 2.0kW of cranking power at 12 volts with clockwise rotation and a 15-tooth pinion, matching the geometry and engagement characteristics of the original Hitachi fitment. Supplied as brand new — not remanufactured — it covers 9 confirmed applications across John Deere, Mustang, and Yanmar platforms.
Verified fitment includes John Deere 3325, 35D, 50D, and 50ZTS; Mustang 930, 930A, and 940; and Yanmar 4TN78 engines. Cross-references span 38 OE and aftermarket numbers from Hitachi, Yanmar, Delco Remy, Isuzu, Prestolite Electric, AD Kuhner, DRI, Sando, Unipoint, and Universal.
