Product Number: 19871N
The WAI 19871N is a brand-new 24V 7.8kW starter motor. It is built to Denso OSGR specification, supplied as a direct replacement for Denso original-equipment references 228000-9630 and 228000-9631, as well as John Deere part number RE505465. Manufactured to Denso design standards, it is suited to the heavy-duty demands of commercial and agricultural machinery where reliable cold-start performance under load is essential.
The OSGR (Off-Set Gear Reduction) design delivers high cranking torque from a compact unit, reducing strain on the ring gear and starter circuit. With clockwise rotation and an 11-tooth pinion, the WAI 19871N matches the engagement geometry of the original Denso unit it replaces. Supplied brand new — not remanufactured — each unit meets the voltage and power output of the OE specification without compromise.

A. The WAI 19871N is a 24V, 7.8kW starter motor with clockwise rotation and an 11-tooth pinion, built to Denso OSGR (Off-Set Gear Reduction) design. It is supplied brand new — not remanufactured.
A. OSGR stands for Off-Set Gear Reduction. This design uses a reduction gear set between the motor and the pinion shaft, which generates higher cranking torque at lower motor speed. The result is a more compact unit that places less stress on the ring gear and starter circuit compared with a direct-drive starter — important for the heavy-duty 24V applications this unit is designed for.
A. The WAI 19871N is supplied brand new. It is not a remanufactured or reconditioned unit.
