Product Number: 33321N
The WAI 33321N is a brand-new 24V 4.8kW starter motor. It is built to the Denso PA90S design, cross-referenced to Denso original-equipment numbers including 428000-7100, 438000-0060 and DensoEURO DSN2091, as well as Cummins reference 4996707. It is engineered for heavy-duty applications where a high-output 24-volt starter is required, delivering reliable cranking performance in demanding conditions.
Constructed to OE specification, the 33321N features clockwise rotation and a 10-tooth pinion drive, matching the geometry of the original Denso PA90S unit. With 4.8kW of output power, it provides the torque necessary for larger diesel engines commonly found in commercial and plant machinery. The part ships as a complete, ready-to-fit unit — no core exchange required.
With 29 cross-references on file across manufacturers including Cummins, Denso, AD Kuhner, Lester, PIC, AES and others, this starter motor covers a wide range of application equivalents. Always verify fitment against your machine's OE number or engine specification before ordering.
