Product Number: 18521N
The WAI 18521N is a brand-new 24V 5.5kW Nikko OSGR starter motor. It is supplied by WAI, designed to replace Komatsu original-equipment starter motors including references 600-813-3320, 600-813-3321 and 600-813-3360, as well as Nikko originals 0-23000-1290, 0-23000-1291 and 0-23000-1292. In total, 11 OE cross-references are held against this part.
This is an OSGR (Off-Set Gear Reduction) design — a configuration commonly specified on heavy plant and construction equipment where a compact, high-torque cranking unit is required. The 11-tooth drive and clockwise rotation are matched to the corresponding ring gear and mounting arrangement of the original Komatsu application. At 5.5kW, this starter delivers the cranking power needed for the larger diesel engines typically found in Komatsu machinery.
The unit is supplied in brand-new condition — not remanufactured — directly sourced from WAI, a specialist in rotating electrics for automotive and plant applications.
