Q 1. What does the WAI 18404N replace — which OE part numbers does it cross-reference?

A. The 18404N carries nine OE cross-references: Denso 128000-7050, Denso 128000-7051, Denso 1280007050, Denso 1280007051, Remy RS41272, Bombardier DAW26844, John Deere AW26844, Kawasaki 21163-2089, and Kawasaki 211632089. Search our cross-referenced catalogue by any of these numbers to confirm the match, or ask Simon if you need further guidance.

Q 2. Does this starter motor replace Denso 128000-7050 or 128000-7051?

A. Yes. Both Denso 128000-7050 and Denso 128000-7051 (along with their unhyphenated variants 1280007050 and 1280007051) are listed cross-references for the WAI 18404N. Denso is the highest-demand reference group for this part with four confirmed refs in total.

Q 3. Is the WAI 18404N a genuine new part or a remanufactured unit?

A. It is supplied brand new — not remanufactured, not on an exchange basis. No core return is required.

Q 4. What are the key electrical and mechanical specs of this starter motor?

A. The 18404N operates at 12V with an output of 0.6kW. It uses the Denso DD design, rotates counter-clockwise (CCW), and has a 9-tooth pinion. These figures should be matched against your original unit or workshop manual before fitting.

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. Can I ask questions about this product before ordering?

A. Yes — ask Simon, or WhatsApp our team on 07754 288583 with any questions about specifications, suitability, or compatibility.
