Q 1. What does the WAI 12324N fit or replace?

A. This alternator is cross-referenced against 13 OE numbers, replacing units from Nissan (refs: Nissan 23100-51H00, Nissan 2310051H00), Hitachi (refs: Hitachi LR225-83, Hitachi LR225-84T, Hitachi LR225-84TR), Denso USA (refs: Denso USA 2109003, Denso USA 2119003), Yanmar (refs: YANMAR 119129-77200, Yanmar 11912977200), and Sando (ref: Sando 20206060). Fitment data covers the Nissan F03 (1989–2003). Use the selection widget or search our cross-referenced catalogue by OEM number or machine model to confirm fit for your application. Fitment is backed by our Fit Guarantee.

Q 2. Does this alternator replace Nissan 23100-51H00?

A. Yes. The WAI 12324N cross-references directly to Nissan 23100-51H00 and Nissan 2310051H00. These are the two Nissan OE references listed for this part. To confirm this is the correct unit for your specific machine or engine variant, search our catalogue by your OEM number or use the selection widget.

Q 3. Which Hitachi part numbers does the WAI 12324N replace?

A. The 12324N replaces six Hitachi references: LR225-83, LR225-84T, LR225-84TR, LR22583, LR22584T, and LR22584TR. If your existing unit carries one of these numbers, the WAI 12324N is the corresponding replacement. Confirm via the catalogue widget or ask Simon if you need further assistance.

Q 4. What are the key electrical specifications of this alternator?

A. The WAI 12324N operates at 24 volts with a 25-amp output. It features an IR/EF (internal regulator, external fan) design, clockwise rotation, and a groove pulley. It is supplied brand new.

Q 5. Does this replace a Yanmar or Denso alternator as well?

A. Yes. In addition to Nissan and Hitachi references, the WAI 12324N cross-references to Denso USA 2109003 and Denso USA 2119003, and to Yanmar 119129-77200 and Yanmar 11912977200. There are 13 OE cross-references in total across all brands. Search our catalogue by any of these numbers to verify fit for your machine.

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. 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.
