Q 1. Which Komatsu OE references does this starter motor replace?

A. The WAI 19932N crosses to eight OE references in total. The Komatsu references include 600-813-3171, 600-813-4190, 6008133171, and 6008134190. The Nikko references include 0-23000-0450, 0-23000-0451, 0-23000-0452, and 0-23000-0455. If your machine carries any of these numbers on its existing starter, the 19932N is the listed replacement. To verify fitment by machine model, use the selection widget or search our cross-referenced catalogue by OEM number — and every cross-reference shown is backed by our Fit Guarantee.

Q 2. What are the key electrical and mechanical specs of this starter motor?

A. The WAI 19932N operates at 24V and produces 2.8kW of output power. It uses an OSGR (Off-Set Gear Reduction) design, rotates clockwise, and engages via a 9-tooth pinion. It is supplied brand new — not remanufactured or exchange.

Q 3. What does OSGR mean, and why does it matter for my machine?

A. OSGR stands for Off-Set Gear Reduction. In this design, an internal gear train reduces the motor speed and multiplies torque before it reaches the pinion, allowing a smaller, lighter motor to deliver strong cranking force. This is the same design as the original Komatsu/Nikko unit, so the WAI 19932N matches the physical envelope, mounting arrangement and ring-gear engagement of the part it replaces.

Q 4. Is this starter motor brand new or remanufactured?

A. It is brand new. The WAI 19932N is manufactured new by WAI to OE specification — it is not a remanufactured core or an exchange unit.

Q 5. How do I confirm this part fits my vehicle or machine?

A. Use the selection widget to match your make, model and engine, or search our cross-referenced catalogue by OEM number, machine model or equivalent part across brands. If your vehicle is not listed, ask Simon. Every fitment shown is backed by our Fit Guarantee.

Q 6. Is this part covered by your Fit Guarantee?

A. Yes. Every vehicle and OE cross-reference shown for this part is checked against manufacturer data and backed by our Fit Guarantee. If it is not right, our Fit Guarantee or hassle-free returns have you covered.
