Alternator, Denso Style, Without Pulley

This is an aftermarket alternator in the Denso style, supplied without a pulley. It fits John Deere 4050 applications and carries reference number 13143. The Denso style designation describes the mounting and housing configuration, so the existing pulley and any required hardware should be transferred from the original unit where the application calls for it. Because the pulley is not included, the correct pulley diameter and belt alignment for the specific machine should be confirmed during selection.
