Q 1. Which machines does the WAI 12169N alternator fit?

A. The 12169N fits Deutz-Fahr, Deutz, Deutz-Allis, Fahr, International, KHD, and Claas agricultural machinery — 60 applications in total. Named models include the Deutz DX130, DX140, DX145, DX160, DX230, DX250, the Deutz-Allis 6265, and the Claas Dominator 100. Use the selection widget to match your exact make, model, and engine, or search our cross-referenced catalogue by OEM number or machine model. Every fitment is backed by our Fit Guarantee.

Q 2. Does this replace the Bosch alternator on my Deutz tractor?

A. Yes — the WAI 12169N crosses to 107 original-equipment references in total, with Bosch numbers including 0 120 400 691, 0 120 400 854, 0 120 400 855, 0 120 400 910, and 0 120 400 911, among others. If your original Bosch unit carries one of those numbers, the 12169N is the confirmed replacement. Search our cross-referenced catalogue by OEM number or ask Simon to verify your exact reference.

Q 3. Does this alternator replace Delco Remy or Iskra units as well as Bosch?

A. It does. Alongside the Bosch cross-references, the 12169N replaces Delco Remy DRB1840 and DRB1840N, and Iskra / Letrika references including IA0570, IA1081, IA1302, Iskra / Letricka tech 11203331, and 11204884 — 107 OE references across all brands in total. Search by your original part number to confirm the match, or ask Simon.

Q 4. Is this a new alternator or a remanufactured one?

A. The WAI 12169N is brand new — not remanufactured or reconditioned. You receive a unit with new brushes, diodes, and bearings as standard, with no service history to account for.

Q 5. Does the 12169N come with a pulley fitted?

A. No — the alternator is supplied without a pulley. You will need to transfer the pulley from the original unit or source one separately before fitting.

Q 6. What is the rotation direction of this alternator?

A. The WAI 12169N rotates clockwise (CW), matching the original Bosch IR/EF specification for the Deutz-Fahr and related applications listed.

Q 7. What does IR/EF mean on this alternator?

A. IR/EF stands for internally regulated and externally fan-cooled. Internal regulation means the voltage regulator is built into the alternator body, eliminating the need for a separate external regulator. External fan cooling means the unit relies on an outside-mounted fan for airflow — consistent with the original Bosch design it replaces.

Q 8. 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.

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.
