Product Number: 18440N
The WAI 18440N is a brand-new 12V 1.2kW starter motor. It is built to Hitachi PMGR specification, replacing Hitachi original-equipment references S114-821, S114-821A, S114821, and S114821A. It also cross-references Yanmar part numbers 118400-77010 and 11840077010, DRI 682041112, and John Deere AM879072 — eight OE references in total, giving strong confidence that this is the correct unit for applications originally equipped with these Hitachi or Yanmar starters.
The PMGR (Permanent Magnet Gear Reduction) design uses a permanent magnet field to deliver reliable cranking torque from a compact, lightweight housing. With 11 drive teeth and counter-clockwise rotation, the unit is engineered to mesh correctly with the ring gear configurations associated with these OE applications. At 1.2kW output on a standard 12V circuit, it provides the cranking power required by the engines it was originally specified for.
Supplied brand new — not remanufactured — the 18440N offers a straightforward like-for-like installation path for anyone working from an OE part number.
