Product Number: 19939N
The WAI 19939N is a brand-new 24V 7.5kW starter motor. It is built to the Nikko OSGR design, cross-referenced directly against Komatsu original-equipment numbers including KOMATSU 600-813-6410, KOMATSU 600-813-6411 and KOMATSU 600-813-6412 — 20 OE references in total across Nikko, Komatsu and Sawafuji fitments. It is designed as a direct replacement for Komatsu plant machinery applications where heavy-duty starting performance and dimensional accuracy to the original are essential.
Manufactured to the OSGR (Off-Set Gear Reduction) design, this starter delivers its 7.5kW output through a 12-tooth drive gear with clockwise rotation — key parameters to verify against your machine's specification before ordering. The OSGR configuration is widely used across Komatsu's heavier plant range, offering reliable engagement under demanding operating conditions.
This starter is confirmed to fit 12 Komatsu applications, including the EG150BS, GD611A, GD661A, PC300, PC300-5, PC300-6, PC300-JP6 and PC310. Use the selection widget or search by OE number to confirm fitment for your specific model and build year.
