Product Number: 12338N
The WAI 12338N is a brand-new 12V 40A alternator. It is built to the Denso IR/IF specification, replacing original-equipment Kubota alternators including 3A011-74010, 3A011-74011, and 3A011-74012, along with Denso references 101211-1180 and 101211-1360 and Bosch Exchange 0986037271 — 23 cross-references in total. It is a direct-fit replacement for Kubota compact tractors, utility tractors, and mini-excavators across 108 confirmed applications.
Constructed to Denso's internal regulator/internal fan (IR/IF) design, the 12338N delivers a clockwise-rotation output at 40 amperes through a groove-type pulley, maintaining the same electrical and mechanical envelope as the factory unit. The IR/IF architecture keeps regulator components inside the housing, reducing external wiring complexity and protecting sensitive electronics from ingress.
Fit coverage spans Kubota models including the KX91-3, L2600DT, L2600F, L2800DT, L2800F, and L2800HST across production years from 1999 to 2010, among 108 verified Kubota applications in total.

Exploring the WAI Starter Motor and Alternator at Partsformachines.com Introduction: In the Plant and Agriculture sector, a starter motor and alternator are parts that ensure a machine runs smoothly. At Partsformachines.com we have partnered with WAI, a global manufacturer of auto and plant machinery parts to off...
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...
