Q 1. Which Generac engines does the WAI 5788N fit?

A. This starter motor fits 5 Generac engine applications: the GN191, GN220, GN320, GN360, and GN410 (all variants). Use the selection widget or search our cross-referenced catalogue by machine model to confirm your exact application. Every fitment shown is backed by our Fit Guarantee.

Q 2. Does the WAI 5788N replace Generac part number 0D9004A or 0E0601?

A. Yes. The WAI 5788N is a direct replacement for Generac OE references including 0D9004A, 0D9004B, 0E0601, 0E06010SRV, 0E0601ASRV, 0E0601SRV, D9004A, D9004B, and E0601 — 9 Generac references in total across 11 cross-references overall. If you are matching by OE number, search our cross-referenced catalogue or ask Simon to confirm.

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

A. The 5788N runs at 12 volts, has counter-clockwise (CCW) rotation, and carries a 10-tooth pinion. It is a PMDD (Permanent Magnet Direct Drive) design supplied brand new by United Technologies.

Q 4. What does PMDD mean and why does it matter for a generator starter?

A. PMDD stands for Permanent Magnet Direct Drive. Instead of wound field coils, the motor uses permanent magnets, which reduces the number of wear components and results in a lighter, simpler assembly. In standby and portable generator applications, this makes for a more dependable starting unit over the long term.

Q 5. Does this replace the Pasco or Powerite Automotive reference for this starter?

A. Yes. In addition to the Generac OE numbers, the WAI 5788N also cross-references Pasco S160227 and Powerite Automotive 5788. Search our catalogue by any of these references to locate the part or ask Simon if you need further confirmation.

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. 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.
