Product Number: 17615N
The WAI 17615N is a brand-new 12V 3.0kW starter motor. It is built to Denso OSGR specification, supplied as a direct replacement for Caterpillar Ag. & Ind. 35 Challenger and 45 Challenger machines (1994–2001). It cross-references 28 OE and aftermarket references, including Denso 128000-5720, Caterpillar 0R4318, and Bosch USA SR5058X, making it a well-documented like-for-like swap for workshop and field use.
Constructed to the original OSGR (Over-running Starter Gene Reduction) design, the unit operates at clockwise rotation and carries a 10-tooth pinion — both critical parameters for correct engagement with the ring gear. At 3.0kW, it delivers the cranking authority these agricultural and industrial Caterpillar machines demand, matching the output of the original Denso-manufactured unit it replaces.
Being brand new rather than remanufactured, no core charge applies and there is no need to return an exchange unit — the motor arrives ready to install. With 28 verified OE cross-references spanning Denso, Caterpillar, CAT, and Bosch, fitment confidence is high before the part even arrives at the machine.
