Q 1. What machines does this alternator fit?

A. The WAI 7256N fits Case, Steiger, and Versatile machines — confirmed applications include the Case 9190 (1987–1991), Steiger Tiger 450 (1982–1985), Steiger Tiger 470 (1982–1985), Steiger Tiger III (1978–1981), Versatile 1150 (1981–1985), and Versatile 1156 (1986–1987), six applications in total. To confirm fitment for your specific machine and engine variant, use the selection widget or search our cross-referenced catalogue by model. Every fitment shown is backed by our Fit Guarantee.

Q 2. Does this replace a Ford original-equipment alternator?

A. Yes. The WAI 7256N cross-references 21 Ford OE numbers, including Ford D7HT-10300-AA, Ford D7HT10300AA, Ford D7HTAA, Ford D8HZ-10346-D, Ford E0HT-10300-AA, Ford E4HT-10300-CA, and Ford Engineering equivalents such as Ford Engineering D7HTAA and Ford Engineering E4HT10300CA. In total there are 43 OE cross-references across brands including Bosch USA, Remy, and Prestolite Electric. Search our cross-referenced catalogue by your OE number to confirm the match, or ask Simon.

Q 3. Does this replace the Bosch USA AL953X or Remy 10459009 alternator?

A. Yes. The WAI 7256N is cross-referenced against Bosch USA AL953X, Remy 10459009, and Remy 1117067, as well as Prestolite Electric 2500LC. All 43 OE references for this part can be searched in our catalogue — if your existing part number matches, this is the confirmed replacement.

Q 4. What are the key specs — voltage, output, and rotation?

A. The 7256N is a 12V, 90A alternator with clockwise (CW) rotation and an internal regulator/internal fan (IR/IF) design, built to the Delco 30SI/TR Series specification. It is supplied brand new and without a pulley, so your original pulley is reused during installation.

Q 5. This is listed without a pulley — do I need to supply one?

A. Yes. The WAI 7256N is supplied without a pulley (w/o pulley). You will need to transfer the pulley from your original alternator or source a suitable replacement separately. This is standard practice for this Delco 30SI/TR Series design.

Q 6. 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 7. Can I ask questions about this product before ordering?

A. Yes — ask Simon, or WhatsApp our team on 07754 288583 with any questions about specifications, suitability, or compatibility.
