Product Number: 18996N
The WAI 18996N is a brand-new 12V 4.8kW starter motor. It is built to Denso OSGR specification, supplied as a direct replacement for Denso original-equipment units referenced as 428000-2860 and TG428000-2860, and for the Cummins application reference 3971603. It is designed for heavy-duty engine starting duties where a reliable, correctly-rated OE-matched unit is essential.
Constructed to OSGR (Offset Gear Reduction) design principles, this starter delivers its 4.8kW output through a 10-tooth drive pinion with clockwise rotation — parameters that must match the ring gear specification of the engine being serviced. The unit arrives ready to fit straight from the box as a brand-new component, requiring no core exchange or rebuilding.
With cross-references covering Denso and Cummins part numbers, this WAI unit is well-suited to workshops and plant operators sourcing a dependable OE-equivalent replacement. Always verify voltage, power rating, tooth count, rotation direction, and mounting configuration against the original unit before fitting.
