Product Number: 6405N
The WAI 6405N is a brand-new 24V 4.5kW starter motor. It is built to the Delco 37MT Series DD design, cross-referenced against Remy 10478811, Remy 1993918 and a range of Caterpillar OE numbers including 0R9727, 2049742 and 8C4774. It is engineered as a direct replacement for original-equipment starters fitted to Caterpillar agricultural and industrial machinery across 10 confirmed applications.
The 37MT Series DD is a well-established direct-drive format used widely in heavy plant and industrial equipment. This unit runs clockwise rotation, carries a 12-tooth drive pinion, and is supplied brand new — not remanufactured — making it a reliable choice for planned maintenance or unplanned breakdown replacement on Caterpillar machines.
Confirmed fitments include the Caterpillar 320, 322L, 325 L, 75 Challenger, 85 Challenger, EL240B, IT12B and IT18F, spanning model years from 1989 to 1998. Always verify against your machine's serial number and engine variant before ordering.
