Product Number: 6633N
The WAI 6633N is a brand-new 24V starter motor. It is built to the Delco 41MT direct-drive (DD) design, replacing original-equipment units from Delco Remy, Remy, AC Delco, and Caterpillar across 42 cross-referenced part numbers. It is engineered for heavy-duty plant and agricultural machinery running 24-volt electrical systems, where reliable cold-start performance and long service life are non-negotiable.
Designed to the proven 41MT direct-drive specification, the 6633N features clockwise rotation and a 12-tooth pinion, matching the geometry of the original Delco unit. Being brand new rather than remanufactured means there is no core charge and no worn internal components — the motor leaves the box ready to install and perform from the first crank.
Verified fitment covers Caterpillar Ag. & Ind. models including the 322L, 938F, and 950F, plus the Atlas Copco XAMS355 compressor — four confirmed applications in total. OE cross-references include Delco Remy DRS3544, Remy 10461085, Remy 10461153, Remy 10461239, CAT 104-7040, CAT 106-8557, and AC Delco 323864 among the 42 listed numbers.
