Product Number: 21009N
The WAI 21009N is a brand-new 12V 80A alternator. It is built to Denso IR/IF specification, replacing Kubota original-equipment references 1J757-64011 and 1J757-64012 along with Denso references 102211-6230 and 102211-6231. It is supplied as a direct replacement unit for applications where the original Denso-design alternator has reached the end of its service life.
The IR/IF (internal regulator / internal fan) design integrates the voltage regulator within the alternator body, removing the need for an external regulator and simplifying installation. Clockwise rotation matches the drive orientation of the original Denso unit, ensuring correct belt engagement without modification.
At 80 amperes output on a 12-volt system, this alternator provides the same charge capacity as the Kubota original-equipment part it replaces. Being brand new — not remanufactured — it carries no prior service hours and requires no core return.
