Product Number: 18548N
The WAI 18548N is a brand-new 24V 4.5kW starter motor. It is built to Denso OSGR specification, replacing original-equipment units referenced under Denso numbers 228000-7900, 228000-7901, 228000-7902 and Cummins reference 3957593 — the most searched equivalent for this part. Designed as a direct OE replacement for heavy-duty diesel applications, it delivers the same output and engagement geometry as the units it supersedes.
The OSGR (Off-Set Gear Reduction) design provides a compact, high-torque output well suited to large-displacement Cummins engines. Clockwise rotation and a 10-tooth pinion ensure correct engagement with the ring gear, while the 4.5kW power output meets the cranking demand of 24V electrical systems found on plant and agricultural machinery.
This starter motor crosses directly to Delco Remy reference DRS0357 and Cummins reference 3934119, in addition to the Denso numbers listed above — giving buyers multiple routes to confirm the correct fitment before ordering.
