Product Number: 12264N
The WAI 12264N is a brand-new 24V 40A alternator. It is built to the Nikko IR/EF design, replacing original-equipment units on Isuzu industrial machinery and Link-Belt construction equipment — including Isuzu miscellaneous industrial equipment and the Link-Belt LS4300. It cross-references Isuzu 1812003970, JCB 40001577, JCB 71436100 and JCB 71440367 among 10 verified OE references, making it a reliable direct replacement for buyers sourcing by OE number.
The IR/EF (internal regulator / external fan) configuration means the voltage regulator is integrated within the alternator body, reducing external wiring complexity on rebuild or swap-out. The groove pulley is ready to accept a standard V-belt drive as fitted to these applications, and the 40A output rating matches the original charging specification for the machines listed.
Fitment covers 2 confirmed applications across Isuzu and Link-Belt platforms spanning model years 1986 to 2007. Buyers with a Komatsu application should note the Komatsu 1812003970 reference is also listed in the cross-reference set, and the AD Kuhner 553031RI and Sando 20506270 numbers are included in the full 10-reference block.

A. The WAI 12264N replaces original-equipment alternators across several brands. Verified references include Isuzu 1812003970, JCB 40001577, JCB 71436100, JCB 71440367, Komatsu 1812003970, NIKKO 0-35000-3370, Nikko 0350003370, AD Kuhner 553031RI, DRI 543145404 and Sando 20506270 — 10 OE references in total. To confirm your number is in the set, search our cross-referenced catalogue by OEM number or ask Simon.
A. Fitment is confirmed on 2 applications: Isuzu miscellaneous industrial equipment (1989–2007) and the Link-Belt LS4300 (1986–2007). Use the selection widget to match your make, model and engine variant, or search by OE number. Every fitment shown is backed by our Fit Guarantee.
A. IR/EF stands for Internal Regulator / External Fan. The voltage regulator is housed inside the alternator body rather than mounted separately on the machine, and the cooling fan sits on the exterior of the unit. This matches the original Nikko design specification for the listed Isuzu and Link-Belt applications, so no external regulator wiring changes are required on a like-for-like replacement.
A. Yes — the alternator is supplied complete with a groove pulley, designed to accept a standard V-belt drive as used on the original Nikko-equipped machines in the fitment list. No separate pulley purchase is needed for a direct replacement.
A. The Komatsu 1812003970 number appears in the verified OE cross-reference set for this part, meaning the alternator is confirmed as a replacement for that original Komatsu part number. To confirm it fits your specific Komatsu machine, search our catalogue by OEM number or ask Simon.
A. Yes — ask Simon, or WhatsApp our team on 07754 288583 with any questions about specifications, suitability, or compatibility.
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.
