Product Number: 6630N
The WAI 6630N is a brand-new 12V 4.5kW starter motor. It is built to the Delco 41MT direct-drive (DD) specification, cross-referenced against Cummins and Remy original-equipment numbers including Cummins 3675208RX, Cummins 3921402, Remy 10461240, Remy 10478818, Remy 10478926, and Remy 10479109. It is engineered as a direct replacement for applications where these OE units were originally fitted, offering workshop-ready reliability straight from the box.
The 41MT DD is a well-established heavy-duty starter design from Delco, specified across demanding industrial and plant applications. This unit delivers a clockwise rotation with a 12-tooth drive, matching the ring-gear engagement geometry of the original equipment. At 4.5kW output it provides the cranking power required by the high-compression engines for which this design was intended.
Fitment data confirms compatibility with the Grimmer Schmidt 800D (1997–2003). With six OE cross-references on record across Cummins and Remy, buyers sourcing by OEM number can verify this unit against their existing part number before ordering.

The best way to find the correct starter motor is to combine the machine and engine details with the OEM or original starter reference, then confirm voltage, rotation, pinion teeth, mounting and terminal position. Do not choose a replacement from appearance alone.
A starter motor usually clicks without cranking because the battery cannot deliver enough current, resistance is present in the battery cables or engine ground, or the starter control circuit and solenoid are not operating correctly. A click does not automatically mean the...
