Q 1. Which Kubota machines does the WAI 12726N fit?

A. This alternator fits six Kubota applications, including the M110DT, M110DTC, M110FC, M120DT, M120DTC and M120FC (model years 1999–2004). To confirm fit for your specific machine, use the selection widget to match by make, model and engine, or search our cross-referenced catalogue by OEM number or machine model. Every fitment shown is backed by our Fit Guarantee.

Q 2. Does this alternator replace Kubota part number 3F261-64010?

A. Yes. The WAI 12726N carries four Kubota OE cross-references: 3F261-64010, 3F261-64011, 3F26164010 and 3F26164011. If your machine is fitted with any of these original-equipment numbers, the 12726N is the corresponding replacement. You can also search our catalogue by OEM number to verify fit for your application.

Q 3. Which Mitsubishi OE numbers does this alternator cross-reference?

A. The WAI 12726N cross-references two Mitsubishi original-equipment numbers: A005TA5999 and A5TA5999. These confirm the Mitsubishi IR/IF design specification this unit is built to.

Q 4. What does IR/IF mean on this alternator?

A. IR/IF stands for Internal Regulator, Internal Fan. It means the voltage regulator is built into the alternator body — no separate external regulator is needed — and the cooling fan is also housed internally. This self-contained design simplifies installation and is the original Mitsubishi specification for the supported Kubota applications.

Q 5. Is this a new alternator or a remanufactured unit?

A. The WAI 12726N is supplied brand new — it is not a remanufactured or reconditioned unit. There is no core deposit and no old-unit return required.

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. 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.
