Product Number: 11903N
The WAI 11903N is a brand-new 12V 60A alternator. It is built to Denso IR specification, supplied as a direct replacement for Kubota original-equipment numbers including 1661564011, 1661564013, 3A611-74012 and 3A61174012, as well as Denso references 101211-8520 and 101211-8521. Designed for agricultural and compact-utility applications, it fits Kubota models including the L5740 and L5740HST (2007–2008) — 2 Kubota applications in total.
The alternator features an internal regulator (IR) design and a groove pulley, matching the original charging-system architecture without modification. At 60 amps output on a 12-volt system, it delivers the same charging capacity as the Denso original it replaces, making it a like-for-like swap suited to routine maintenance and unplanned failures alike.
With 11 OE cross-references spanning Kubota, Denso, AD Kuhner, and Pasco, the 11903N is a well-documented replacement unit. It is supplied brand new — not remanufactured — ensuring full service life from installation.

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.
