Alternator for John Deere Marine Backloaders & Crawlers 4045TFM

John Deere marine, backloader and crawler alternator, fits 4045TFM engines

This alternator is built for John Deere marine engines, backloaders and crawlers, including the 4045TFM engine, engineered to OEM specifications for a direct fit and function replacement across this equipment range.

It runs at 12 volts with a 65 amp output, uses a bi-directional fan and rotation to suit the demands of marine and industrial duty cycles, and is internally regulated (IR) so no separate external regulator is needed. The rotor shaft measures 0.625 inches, matching the original John Deere specification for this application.
