Q 1. What does the WAI 19942N replace — which OE part numbers does it cross-reference?

A. The WAI 19942N is cross-referenced against eight OE part numbers. Komatsu references covered include 600-863-3110, 600-863-3210 and 600-863-3211. Nikko original references are 0-24000-0030, 0-24000-0040 and 0-24000-0041. Additional cross-references are AD Kuhner 254909 and Farcom 107014. Search our cross-referenced catalogue by your original OE number to confirm a match, or ask Simon if you are unsure.

Q 2. Which machines or vehicles does this starter motor fit?

A. Specific vehicle or machine fitment data is not published for this part. The OE cross-references — Komatsu 600-863-3110, 600-863-3210 and 600-863-3211, along with the Nikko, AD Kuhner and Farcom numbers — are the primary means of confirming fit. Search our cross-referenced catalogue by your OEM number or machine model, or ask Simon. Every fitment shown is backed by our Fit Guarantee.

Q 3. What are the key specifications of the WAI 19942N starter motor?

A. This is a brand-new Nikko-design OSGR starter motor rated at 24V and 3.0kW output. It has clockwise (CW) rotation and an 11-tooth pinion. Confirm that your engine ring gear matches both the tooth count and the rotation direction before fitting.

Q 4. What does OSGR mean, and why does it matter?

A. OSGR stands for Off-Set Gear Reduction. In this design, a reduction-gear stage sits between the motor armature and the drive pinion, allowing the motor to spin faster internally while delivering higher cranking torque at the pinion. The result is a compact unit capable of the sustained output required to crank large diesel engines reliably in heavy plant and machinery applications.

Q 5. 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.

Q 6. 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.
