Product Number: 16981N
The WAI 16981N is a brand-new 12V 2.5kW Denso-design OSGR starter motor. It is built to replace original Denso equipment across Gradall telescopic handler and excavator applications. Supplied as a direct replacement for Denso references including 128000-2250, 128000-2251, 128000-2252 and 128000-2253, it also cross-references to Bosch USA SR9977X and WHITE 40-2500442 — 11 OE references in total.
The OSGR (Off-Set Gear Reduction) design delivers efficient cranking from a compact, robust package. Clockwise rotation and a 10-tooth pinion ensure correct engagement with the ring gear, while the 2.5kW output provides the starting torque these demanding Gradall machines require.
Fitment covers 7 Gradall applications, including the 534B6, 534B8, 534B9, 544, B, and GW3 — verify your specific model and engine variant using the selection widget or by searching our OEM cross-referenced catalogue. The Fit Guarantee applies to every confirmed application.
