Q 1. What does this starter motor replace — which original-equipment numbers does it cross-reference?

A. The WAI 18818N is a direct replacement for Bombardier A31200-179-000 and A31200179000. It also cross-references Pasco S1010529 and Powerite Automotive 18818 — four OE references in total. If you are searching by one of those numbers, this is the corresponding WAI part. To confirm fitment to your specific machine or variant, use the selection widget or search our cross-referenced catalogue by OEM number or machine model.

Q 2. What are the key specifications — voltage, rotation and tooth count?

A. The 18818N runs on a 12V electrical system, turns clockwise (CW), and uses a 9-tooth drive pinion. The design is PMDD (permanent-magnet direct-drive), and the unit is supplied brand new by Mitsuba.

Q 3. What is PMDD, and why does it matter for a starter motor?

A. PMDD stands for permanent-magnet direct-drive. Instead of wound field coils, the stator uses permanent magnets to generate the magnetic field, which results in a more compact and lightweight unit. This design is common in OE applications where packaging space is limited and consistent cranking performance is required.

Q 4. 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.

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.
