Product Number: 19451N
The WAI 19451N is a brand-new 12V 1.2kW permanent-magnet gear-reduction (PMGR) starter motor. It is built to Hitachi specification, cross-referenced against Hitachi S114-940 and S114940, Yanmar 119125-77010 / 119125-77011 / 119125-77012, and Bobcat 7018593 among twelve verified OE references. It is a direct replacement for worn or failed units on equipment that originally carried these Hitachi-design starters.
The PMGR design uses a permanent-magnet field rather than wound-field poles, which reduces internal resistance, lowers current draw at cranking, and delivers reliable torque from a compact, lightweight package. Clockwise rotation, nine-tooth drive, and 12V electrics are fixed by design — confirm these parameters match your existing unit before fitting.
With twelve OE cross-references spanning Hitachi, Yanmar, Bobcat, Polaris, Sando, and AD Kühner, this starter covers a broad spread of compact plant, agricultural, and utility equipment. The WAI brand is a recognised OE-quality remanufacturing and new-parts supplier; this unit is supplied as brand new, not remanufactured.

A. The WAI 19451N crosses to 12 verified OE references including Hitachi S114-940 and S114940, Yanmar 119125-77010, 119125-77011, and 119125-77012 (also listed as Yanmar 11912577010, 11912577011, and 11912577012), Bobcat 7018593, Polaris 3070309, Sando 60202341, and AD Kuhner 255312. To confirm fit for your specific machine, search our cross-referenced catalogue by OEM number or machine model, or ask Simon. Every cross-reference shown is backed by our Fit Guarantee.
A. Fitment is defined by the OE cross-references listed — this starter is designed to replace units carrying Hitachi, Yanmar, Bobcat, Polaris, Sando, or AD Kühner original-equipment part numbers as detailed above. Vehicle-specific application data is not published for this part. Use our cross-referenced catalogue search by OEM number, or ask Simon with your machine make, model, and engine details to confirm suitability.
A. The WAI 19451N is supplied brand new — it is not a remanufactured or reconditioned unit.
A. The 19451N operates at 12V with a power output of 1.2kW. It uses a permanent-magnet gear-reduction (PMGR) design, runs with clockwise rotation, and has a 9-tooth drive pinion. These parameters must match your existing starter before ordering.
A. PMGR stands for Permanent-Magnet Gear Reduction. The design uses permanent magnets in the field rather than wound poles, which reduces internal resistance and current draw at cranking. A gear-reduction mechanism steps down motor speed to deliver higher torque to the ring gear — characteristics that make this design well suited to the compact plant and agricultural equipment it is cross-referenced to.
A. Use the selection widget to match your make, model and engine, or search our cross-referenced catalogue by OEM number, machine model or equivalent part across brands. If your vehicle is not listed, ask Simon. Every fitment shown is backed by our Fit Guarantee.
A. Yes — ask Simon, or WhatsApp our team on 07754 288583 with any questions about specifications, suitability, or compatibility.
