Product Number: 18084N
The WAI 18084N is a brand-new 24V 7.5kW OSGR starter motor. It is built by Nikko, designed as a direct replacement for Komatsu original-equipment starter numbers including KOMATSU 600-813-4530, KOMATSU 600-813-4531, and KOMATSU 600-813-4532 — part of a 20-reference cross-reference list covering 12 Komatsu OE numbers in total. It is engineered to fit 32 Komatsu applications, including the D50, D50A, D53, D53A, D53P, D53S, D58, and D58E series spanning production years from the mid-1980s through to 1997.
The OSGR (Off-Set Gear Reduction) design delivers reliable cranking performance in demanding plant and construction environments. Clockwise rotation and a 12-tooth pinion ensure correct engagement with the ring gear on compatible Komatsu engines, while the 24-volt, 7.5kW output provides the sustained starting power these heavy-duty machines require.
Supplied brand new, this is a like-for-like replacement rather than a reconditioned or remanufactured unit, giving you confidence in service life from the moment of fitment.
