Q 1. Which Ford and Denso part numbers does the WAI 34018N replace?

A. The WAI 34018N is a direct replacement for the following OE references: Ford 4R3T11000AA, Ford 4R3T11000AB and Ford 4R3Z11002AA, plus Denso 2818001, Denso 428000-3290 and Denso 4280003290 — six references in total. If your existing starter carries one of these numbers, the 34018N is the confirmed replacement. To verify fitment for your machine or vehicle, search our cross-referenced catalogue by OEM number, or ask Simon. Every OE cross-reference shown is backed by our Fit Guarantee.

Q 2. What are the key specifications of this starter motor?

A. The WAI 34018N operates on a 12V system with a rated output of 1.4kW. It uses a PMOSGR (permanent-magnet offset-geared reduction) design, rotates clockwise, and has an 11-tooth pinion. It is supplied brand new — not remanufactured.

Q 3. What does PMOSGR mean on a starter motor?

A. PMOSGR stands for permanent-magnet offset-geared reduction. This design uses permanent magnets in place of field windings and incorporates a reduction gear between the motor and the pinion, allowing a more compact and lightweight unit to deliver the torque needed to crank the engine. It is the design type specified for this Denso-pattern unit.

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

A. The WAI 34018N is supplied brand new. It is not a remanufactured or exchange unit.

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.
