Product Number: 18181N
The WAI 18181N is a brand-new 24V 4.5kW starter motor. It is built to Denso OSGR specification, cross-referenced against 25 OE and aftermarket part numbers including Denso 028000-5530, Denso 028000-5690, Toyota 28100-56030, and Delco Remy DRS3184. It is a direct replacement for the original-equipment Denso unit and is confirmed to fit the Toyota BJ42 and Toyota BJ46 (both 1985 applications).
The OSGR (Off-Set Gear Reduction) design delivers efficient cranking power for demanding 24V diesel applications. Clockwise rotation and an 11-tooth pinion gear match the original flywheel ring-gear specification, ensuring correct engagement and reliable starting performance. Supplied as a complete, ready-to-fit unit in brand-new condition, this motor requires no core exchange or refurbishment.
With 25 OE cross-references spanning Denso, Delco Remy, Toyota, DRI, and Unipoint, this starter motor covers a tightly defined set of applications — always verify your vehicle's engine variant and original part number before ordering to confirm fitment.
