Product Number: 12351N
The WAI 12351N is a brand-new 12V 55A alternator. It is built to Denso IR/IF specification, replacing Denso original-equipment references 101211-2200 and 101211-2201 and their Yanmar equivalents 129052-77220. It is designed as a direct replacement for the alternator fitted to the John Deere 4100 compact utility tractor, restoring charging performance to the original specification without modification.
Constructed to Denso's internal-regulator, internally-fused (IR/IF) design, the unit incorporates an integral voltage regulator — eliminating the need for an external regulator and simplifying installation. The groove pulley drive is compatible with the standard belt arrangement on supported applications, and the brand-new condition means no core exchange, no reconditioning risk and no unknown service history to contend with.
With nine cross-referenced OE numbers catalogued against this unit — including Denso, Yanmar, AD Kuhner, DRI and John Deere — sourcing confidence is high for workshops verifying the correct part against their workshop management system or parts catalogue.

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...
