Product Number: 19849N
The WAI 19849N is a brand-new 12V 5.0kW Denso PLGR starter motor. It is supplied as a direct replacement for Denso original-equipment units including 428000-0120 and 428000-0121, and for John Deere OE references including RE501862 and RE506825. Eleven references in total are cross-listed for this part. It is designed to fit John Deere equipment across 11 applications — covering large-frame 4WD and tracked models in the 9000 Series as well as the 7700 — making it a dependable like-for-like swap for end-of-life or failed original starters on high-output agricultural machinery.
Built to Denso's PLGR (Permanent Magnet Gear Reduction) design, the 19849N delivers 5.0kW of cranking power from a 12V supply with clockwise rotation and a 13-tooth pinion. The PLGR format is well established in demanding agricultural and construction applications: compact form, high torque output, and strong resistance to the heat and vibration cycles that are a fact of life in the field. Supplied brand new — not remanufactured — every unit leaves the warehouse ready to fit.
Refer to the specification table below for the full verified figures. To confirm fit against your specific John Deere model or engine variant, use the selection widget, search the cross-referenced catalogue by OEM number or machine model, or ask Simon. Every fitment shown is backed by our Fit Guarantee.
