Product Number: 17391N
The WAI 17391N is a brand-new 24V 5.5kW starter motor. It is built to Denso OSGR specification, designed to replace original Denso, Remy, and Case equipment on Case and Samsung plant machinery. With 28 Case applications and 2 Samsung applications in the fitment database — covering excavators, crawler dozers, and wheeled loaders from the late 1980s through the early 2000s — this unit is a proven like-for-like replacement for demanding plant environments.
The OSGR (Over-running Starter with Gear Reduction) design delivers efficient, reliable cranking power suited to the high-compression diesel engines found in heavy plant machinery. Clockwise rotation and a 10-tooth pinion ensure correct engagement with the ring gear, while the 24V electrical system matches standard heavy-equipment wiring harnesses without modification.
This starter motor cross-references 12 Denso, Remy, and Case OE part numbers, including Denso 128000-2560, 128000-2561, 128000-2562, 128000-2563, Remy 69026, Case 1987566C1, and Case D129494, among others — making positive identification straightforward when sourcing by OE reference.

A. The WAI 17391N is a brand-new Denso-specification OSGR starter motor rated at 24V and 5.5kW. It features clockwise (CW) rotation and a 10-tooth pinion drive, matching the electrical and mechanical requirements of the original equipment it replaces on Case and Samsung plant machinery.
A. OSGR stands for Over-running Starter with Gear Reduction. This design uses an internal reduction gear set to multiply torque at the pinion, allowing a smaller, lighter motor to deliver the cranking force needed for high-compression diesel engines — the type commonly found in the Case excavators, crawler dozers, and wheeled loaders this unit is designed for.
