Q 1. Which OE starter motors does the WAI 18010N replace?

A. The 18010N is cross-referenced against seven original-equipment part numbers including Denso 128000-5500, Denso 1280005500, Denso 9712809550, Remy RS41281, John Deere AM105575, Kawasaki 21163-2077, and Kawasaki 211632077. Search our cross-referenced catalogue by any of these OEM numbers to confirm fitment, or ask Simon if you need further guidance. Every OE cross-reference shown is backed by our Fit Guarantee.

Q 2. Does this starter motor replace the Denso 128000-5500?

A. Yes. The WAI 18010N carries Denso references 128000-5500, 1280005500, and 9712809550 as verified cross-references, making it a direct OE-equivalent replacement for those Denso units. Use our catalogue's OEM number search to confirm your application before ordering.

Q 3. What are the key specifications of the WAI 18010N?

A. The 18010N is a 12V, 0.6kW permanent-magnet direct-drive (PMDD) starter motor with counter-clockwise (CCW) rotation and a 9-tooth pinion. It is supplied brand new — not remanufactured — and is built to Denso manufacturer specification.

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

A. The WAI 18010N is brand new. It is not a remanufactured or reconditioned part, so there are no pre-existing wear concerns from a previous service life.

Q 5. What does PMDD mean and why does it matter for a starter motor?

A. PMDD stands for Permanent Magnet Direct Drive. In a PMDD starter the field is generated by permanent magnets rather than wound coils, which simplifies the construction, reduces weight, and provides consistent cranking torque. The WAI 18010N replicates the original Denso PMDD design.

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.

Q 7. Where can I find related spares and accessories for this product?

A. Compatible spares and accessories are shown on the Related Accessories tab of this product page, and common parts across the brands we stock are in our Parts & Spares section.
