Q 1. Does this alternator replace Bosch 0 120 488 296 — and what other Bosch numbers does it cross to?

A. Yes. The WAI 12224N is a direct replacement for Bosch 0 120 488 296 (also listed as 0120488296), along with Bosch 9 120 006 023, 9 120 060 023, 9120006023, 9120060023, Bosch Exchange 0986UR0781, Bosch F 005 A00 026, F005A00026, Bosch USA AL928N and AL928X — 11 Bosch references in total across 51 OE cross-references for this part. To verify fit by OE number, search our cross-referenced catalogue or use the selection widget.

Q 2. Will this fit my Thermo King or John Deere machine?

A. The WAI 12224N fits 30 applications across Thermo King and John Deere, including the Thermo King SB-190, SB-200, SB-210, SB-300, SB-310, LND 50 and SB-II series, as well as the John Deere 650H (1998–2007) — 29 Thermo King models and 1 John Deere application in total. Use the selection widget to match your exact model and year, or search by OEM number. Every fitment shown is backed by our Fit Guarantee.

Q 3. Does it replace Thermoking part number 41-8463?

A. Yes — THERMOKING 41-8463 is one of the 51 OE cross-references carried for the WAI 12224N. Additional Thermo King references include THERMO KING 10415457B, 10449572, 1E32216G01 and 20415457. Search our catalogue by any of these numbers to confirm fit for your unit.

Q 4. Does this replace Remy or Prestolite alternator numbers?

A. Yes. The WAI 12224N cross-references to Remy 50955 and Remy 93070, and to Prestolite Electric 66021606. If you are working from a Remy or Prestolite part number, use our OEM search to confirm the match before ordering.

Q 5. What are the key electrical and mechanical specifications?

A. The 12224N is a 12V, 65A alternator with clockwise (CW) rotation and Bosch IR/EF design (internally regulated, externally fused). It is supplied without a pulley — the original pulley from the unit being replaced should be transferred across during installation. It is brand new, not a remanufactured or exchange unit.

Q 6. Does this come with a pulley, and what does IR/EF mean?

A. The unit is supplied without a pulley (w/o Pulley); you will need to reuse the pulley from the alternator being replaced, or source one separately if required. IR/EF stands for Internal Regulator / Externally Fused — a Bosch design convention indicating that the voltage regulator is built into the alternator body and the excitation circuit is externally fused, which is standard for this OE specification.

Q 7. Is this a new unit or a remanufactured exchange?

A. The WAI 12224N is a brand-new alternator — not reconditioned, remanufactured, or supplied on an exchange basis. No core return is required.

Q 8. 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 9. 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.
