Product Number: 18105N
The WAI 18105N is a brand-new 24V 7.5kW starter motor. It is built to the Nikko OSGR design, supplied as a direct replacement for Komatsu original-equipment numbers including KOMATSU 600-813-3660, KOMATSU 600-813-3661, and KOMATSU 600-813-3662. Engineered for heavy plant equipment, it is confirmed to fit the Komatsu PC200 and Komatsu PC220 — covering 2 Komatsu applications in total.
The OSGR (Off-Set Gear Reduction) design delivers reliable, efficient cranking in demanding site conditions. With a clockwise rotation, 13-tooth pinion, and a full 7.5kW output at 24 volts, this unit is built to the same operating specification as the Nikko originals it replaces, with cross-references including NIKKO 0-23000-6510, NIKKO 0-23000-6513, and NIKKO 0-23000-7911 (13 OE references in total).
Every unit is supplied in brand-new condition — not remanufactured — giving you a clean, out-of-the-box installation without the risk associated with rebuilt cores.
