Q 1. What Kubota part numbers does the WAI 12656N replace?

A. The WAI 12656N cross-references eight Kubota original-equipment numbers, including Kubota 16615-64011, Kubota 16615-64012, Kubota 12905277220, Kubota 1661564011, Kubota 1661564012, Kubota 3A61174011, Kubota TA043-74011, and Kubota TA04374011. In total, 19 OE cross-references are verified for this part across multiple brands. Use the selection widget or search our cross-referenced catalogue by OEM number to confirm fitment for your machine, or ask Simon. Every cross-reference is backed by our Fit Guarantee.

Q 2. Which machines does this alternator fit?

A. The WAI 12656N has three confirmed vehicle applications: the Massey Ferguson MF-1547 (2005–2015), the Iseki TG5390 (2005–2015), and the Thomas Equipment T95 (1994–2007). Use the selection widget to match your make, model, and engine variant, or search our catalogue by machine model. If your machine is not listed, ask Simon — fitment is backed by our Fit Guarantee.

Q 3. Does this replace Denso and Delco Remy alternator numbers too?

A. Yes. In addition to the Kubota references, the WAI 12656N cross-references six Denso numbers including Denso 101211-2490, Denso 101211-2850, and Denso 1012112490, as well as Delco Remy DRA0316, Komatsu TA04374012, Farcom 113702, DRI 583109602, and Sando 20401770 — 19 verified OE references in all. Search our catalogue by any of these numbers to confirm suitability.

Q 4. Is this a remanufactured unit or brand new?

A. The WAI 12656N is supplied brand new — not remanufactured, not reconditioned. There is no core return or exchange requirement.

Q 5. What is the output and rotation of this alternator?

A. The 12656N is rated at 12V and 60A output, with clockwise (CW) rotation, a groove pulley, and a Denso IR/IF (internal regulator, internally fused) design. These specifications are confirmed in the technical data above.

Q 6. What does the IR/IF design mean for installation?

A. IR/IF stands for Internal Regulator / Internal Fan. The voltage regulator is housed inside the alternator casing, so there is no separate external regulator to wire or replace — the unit mounts directly in place of the original Denso-spec alternator.

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

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

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.
