Denso 12V 140A Alternator for AG-CHEM Terragator 6103 & John Deere 6081AFM75 / 6125AFM75 / 6125SFM75

This alternator is designed for high-demand agricultural and industrial equipment, supporting models such as the AG-CHEM 6103 Terragator (1998-2004) and John Deere 6081AFM75, 6125AFM75, and 6125SFM75 engines produced between 2004 and 2007. Built for machines operating in heavy-duty environments, the unit delivers a 12-volt, 140-amp output with an 8-groove pulley configuration, aligning with the original Denso design used in these applications.

It replaces multiple OEM and aftermarket references, including WAI 12658N, Denso 101211-7780, John Deere RE500226, and SE501839, offering direct compatibility for equipment requiring precise electrical performance during continuous operation.

Constructed with 100 percent new components, the alternator provides consistent charging capability for machinery that often runs extended cycles under load. Its manufacturing process follows strict standards to maintain structural reliability, accurate mounting alignment, and stable output comparable to original equipment. This supports dependable electrical supply for essential systems across field operations, power units, and other agricultural work conditions.
