Product Number: 19774N
The WAI 19774N is a brand-new 24V 7.5kW OSGR starter motor. It is manufactured by Nikko, designed to replace original-equipment units on Komatsu heavy plant machinery. It cross-references directly against Komatsu OE numbers including 600-813-4680, 600-813-4681 and 600-813-4682, covering 25 verified references in total across both Komatsu and Nikko fitment data. Confirmed applications include the Komatsu WA450, WA470 and WF450T-1 across three Komatsu model lines.
As an OSGR (Off-Set Gear Reduction) unit, this starter delivers reliable cranking performance suited to the demanding duty cycles of construction and plant equipment. The clockwise-rotation motor drives through a 12-tooth pinion, matching the ring gear specification of the original Nikko unit it replaces.
Supplied brand new, this is a direct OE-specification replacement rather than a remanufactured unit, giving confidence in service life from the outset.
