Product Description

The ATG10677 Alternator is a new aftermarket replacement designed for selected John Deere industrial and marine engine applications. It operates on a 12V electrical system and delivers a 90 Amp output to support battery charging and electrical power requirements in compatible equipment.

This alternator features an internal regulator (IR) and is cross-referenced to John Deere part numbers RE50411 and RE50811. Additional references from ARCO Marine, Arrowhead, Cargo, J & N, Lester, Motorola, and Prestolite help identify potential replacement applications.

Listed applications include John Deere 4039 and 4045 engines, with specific marine fitment records for the 4039DFM engine in 3.9L (239 cu in) four-cylinder configurations. The supplied product title also references 6068 and 6076 marine engines, but detailed fitment records for those models were not provided. Confirm the original alternator number, mounting configuration, pulley, connector, and electrical specifications before ordering.
