Q 1. What does the WAI 7263N replace, and will it fit my machine?

A. The WAI 7263N is a direct replacement for Cummins original-equipment numbers including Cummins 30000347, Cummins 3000347 and Cummins 3604685RX; Remy numbers including Remy 1117648, Remy 1117734 and Remy 1117735; Caterpillar numbers 0R5203 and 4N3986; Case 104258A1; Prestolite 110-459 and Prestolite Electric 110459; AC Delco 321642 and AC Delco 321645; and others — 20 OE cross-references in total. Confirmed vehicle fitments include the Caterpillar Ag. & Ind. 130G, PR450, PR450C and PR750B (4 applications). Use the selection widget or search our cross-referenced catalogue by OEM number or machine model to verify your exact application. Every fitment shown is backed by our Fit Guarantee.

Q 2. Does this alternator replace Cummins part numbers 30000347 or 3604685RX?

A. Yes. The WAI 7263N cross-references all three Cummins numbers on this part: Cummins 30000347, Cummins 3000347 and Cummins 3604685RX. If you are sourcing against a Cummins OE number, search our catalogue by that reference to confirm the application match, or ask Simon for assistance.

Q 3. Does it replace Remy or AC Delco alternator numbers?

A. Yes. Seven Remy references are cross-referenced to this part — Remy 1117648, Remy 1117734, Remy 1117735, Remy 1117743, Remy 1117746, Remy 1117826 and Remy 1117834 — along with AC Delco 321642 and AC Delco 321645. Search by any of these numbers in our catalogue to confirm fitment for your machine.

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

A. The WAI 7263N operates at 24V with a 60A output. It follows the Delco 30SI Series IR/EF design — internal regulator, external fan — and supports bi-directional rotation. It is supplied without a pulley, so the original pulley is transferred during installation.

Q 5. Why does it come without a pulley, and is that normal?

A. Yes, this is standard practice for this type of replacement alternator. The unit is listed as w/o Pulley, meaning you reuse the pulley from the original unit. This ensures the correct pulley ratio and belt alignment for your specific machine is maintained without any additional parts.

Q 6. Is this a brand-new alternator or a remanufactured unit?

A. This is a brand-new alternator — not remanufactured and not reconditioned. There is no core exchange requirement and no uncertainty about internal condition on arrival.

Q 7. What Caterpillar machines does the WAI 7263N fit?

A. Confirmed Caterpillar Ag. & Ind. fitments are the 130G (1994–1995), PR450 (1992), PR450C (1992) and PR750B (1993) — four applications in total. Use the selection widget or cross-reference the Caterpillar OE numbers 0R5203 or 4N3986 in our catalogue to verify fit for your specific serial range.

Q 8. What does IR/EF mean on this alternator?

A. IR/EF stands for Internal Regulator / External Fan. The voltage regulator is built into the alternator body rather than mounted separately on the machine, and the cooling fan sits on the exterior of the unit. This is the standard 30SI Series configuration used across a wide range of Delco-equipped plant and agricultural machinery.

Q 9. 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 10. 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.
