Product Number: 19851N
The WAI 19851N is a brand-new 12V 5.0kW starter motor. It is supplied as a direct replacement for Denso original-equipment units, including Denso 428000-3320 and Denso DSN2022, as well as John Deere reference RE520634. It is engineered for fitment on John Deere T660 and T670 combine harvesters, covering all engine variants of both machines.
Built to OE specification, the 19851N delivers clockwise rotation and carries an 11-tooth pinion, matching the geometry and engagement characteristics of the Denso units it replaces. At 5.0kW cranking output, it provides the sustained starting power these large agricultural machines demand — particularly important in cold-morning field conditions where a reliable crank is critical to productivity.
As a brand-new unit rather than a remanufactured exchange, the 19851N requires no core return and arrives ready to fit straight from the box.
