Q 1. What does the WAI 12323N replace, and will it fit my Isuzu machine?

A. The WAI 12323N replaces Hitachi original-equipment alternators referenced as LR220-27, LR220-27B, LR22027, and LR22027B, as well as Delco Remy DRA1324 and Isuzu OE numbers 8943388470 and 8943388471 — 12 cross-references in total across brands including AD Kuhner, BTS Turbo, DRI, Farcom, and Sando. Fitment data covers Isuzu industrial equipment produced between 1983 and 2004. Use the selection widget or search our cross-referenced catalogue by OEM number or machine model to confirm your exact application. Fitment shown is backed by our Fit Guarantee.

Q 2. Does this alternator replace Hitachi LR220-27 and LR22027?

A. Yes. The WAI 12323N directly crosses to Hitachi LR220-27, LR220-27B, LR22027, and LR22027B — the four Hitachi references on this part. If you are searching by one of those numbers, this is the corresponding WAI unit. Search our catalogue by OEM number to verify against your existing part.

Q 3. Will this alternator replace a Delco Remy DRA1324?

A. Yes — Delco Remy DRA1324 is one of the 12 OE cross-references carried by the WAI 12323N. If your machine currently runs a DRA1324, the 12323N is the corresponding replacement. Confirm via the selection widget or OEM number search, or ask Simon if you need further guidance.

Q 4. What are the key electrical and mechanical specifications?

A. The WAI 12323N is a 24V, 20A alternator built to the Hitachi IR/EF design, meaning it uses an internal voltage regulator and an external fan. Rotation is clockwise (CW) and the unit is fitted with a groove pulley. It is supplied brand new.

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. 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.
