Q 1. Which Honda original-equipment starter motor does this replace?

A. The WAI 18667N cross-references directly to Honda OE numbers 31200-HN8-000, 31200-HN8-003, 31200HN8000, and 31200HN8003 — four Honda references in total. It also replaces Remy RS41251. If your existing unit carries any of those numbers, this is the correct replacement. To confirm fit by machine model or engine variant, use the selection widget or search our cross-referenced catalogue by OEM number. Every OE cross-reference shown is backed by our Fit Guarantee.

Q 2. Does this replace the Remy RS41251 starter motor?

A. Yes. Remy RS41251 is one of the five OE cross-references held on this part. The WAI 18667N is a brand-new Mitsuba-manufactured PMDD unit built to the same specification, so it is a direct replacement for that Remy reference.

Q 3. What are the key technical specs — voltage, rotation, and tooth count?

A. The 18667N runs on 12V, rotates counter-clockwise (CCW), and has a 9-tooth pinion. The design is PMDD (permanent-magnet direct-drive). All three of these figures — voltage, rotation direction, and tooth count — should be matched to your application before ordering.

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

A. It is brand new. The WAI 18667N is supplied as a new unit with no prior usage, so there is no core return required and no concern about the condition of internal components.

Q 5. 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.

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.
