Q 1. Which OE part numbers does the WAI 5745N replace?

A. The WAI 5745N cross-references five OE part numbers: Remy 96764 and Remy RS41076, plus Briggs & Stratton 391178, Briggs & Stratton 394807, and Briggs & Stratton 396306. If your existing starter carries any of these references, the 5745N is the correct WAI replacement. For further confirmation, search our cross-referenced catalogue by OEM number or ask Simon.

Q 2. Does this starter motor fit my Briggs & Stratton engine?

A. Vehicle and machine fitment data is not published for this part in our current catalogue. The most reliable way to confirm fit is to match against the OE part numbers listed above — if your original starter is a Remy 96764, RS41076, or a Briggs & Stratton 391178, 394807, or 396306, this is the correct replacement. You can also search our cross-referenced catalogue by OEM number or ask Simon for guidance. Every OE cross-reference shown is backed by our Fit Guarantee.

Q 3. What are the key technical specifications of the 5745N?

A. The WAI 5745N is a 12V PMDD (Permanent Magnet Direct Drive) starter motor with counter-clockwise (CCW) rotation and a 16-tooth pinion. It is supplied brand new and is built to replace the Briggs & Stratton and Remy original-equipment units listed in the cross-references above.

Q 4. What does PMDD mean on a starter motor?

A. PMDD stands for Permanent Magnet Direct Drive. It means the motor uses permanent magnets in place of wound field coils, and the drive engages the ring gear directly without a reduction gear set. This design is compact, efficient, and has fewer moving parts than older wound-field or planetary-gear starters — making it a durable choice for small-engine applications such as those covered by the Briggs & Stratton OE references this unit replaces.

Q 5. 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 6. 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.
