Product Number: 12807N
The WAI 12807N is a brand-new 12V 40A alternator. It is built to Denso IR/IF specification, replacing Kubota original-equipment reference 16404-64012 (also listed as 1640464012) and Denso references 101211-1030 and 1012111030. It is designed for Kubota applications, with a confirmed fit for the Kubota RX502 (1980–1999).
Constructed to internal-regulator, internal-fan (IR/IF) design, this alternator delivers a clean 40-amp output at 12 volts — the correct charging specification for the machines it replaces. Clockwise rotation and a groove pulley ensure direct mechanical compatibility with the original drive arrangement, so fitment is straightforward without modification.
Supplied brand new — not reconditioned or remanufactured — the 12807N offers a cost-effective, like-for-like replacement when the original Denso or Kubota unit fails. The Sando cross-reference 20402501 is also carried on this part for catalogue identification.

The best way to find the correct starter motor is to combine the machine and engine details with the OEM or original starter reference, then confirm voltage, rotation, pinion teeth, mounting and terminal position. Do not choose a replacement from appearance alone.
A starter motor usually clicks without cranking because the battery cannot deliver enough current, resistance is present in the battery cables or engine ground, or the starter control circuit and solenoid are not operating correctly. A click does not automatically mean the...
