Product Number: 12204N
The WAI 12204N is a brand-new 12V 45A alternator. It is built to Denso IR/IF specification, supplied as a direct replacement for original-equipment Kubota and Denso alternators across five Kubota agricultural tractor applications spanning 1988 to 2007. It carries verified OE cross-references including Kubota 16451-64011, Kubota 16541-64011, and Denso 100211-6780, making identification straightforward for workshop and fleet buyers alike.
Constructed to the internal regulator, internally fanned (IR/IF) design standard, the unit delivers 45 amps at 12 volts with clockwise rotation and is fitted with a groove pulley — matching the original Denso charging-system geometry without modification. Being brand new rather than remanufactured, it arrives ready to fit without the uncertainty of exchange core conditions or unknown service history.
Fitment covers Kubota models including the M7580DT and the M8580DT range (M8580DT, M8580DTC, M8580DTM), with full OE cross-referencing across seven Kubota and Denso part numbers. Use the selection widget or search the cross-referenced catalogue by OEM number to confirm fit for your specific machine variant.
