Product Number: 7129N
The WAI 7129N is a brand-new 24V 40A alternator. It is built to the Delco 10SI Series IR/EF specification, replacing Remy original-equipment numbers 1102916, 20038 and 91751, as well as John Deere references SE501377 and TY6752. It is engineered for demanding plant and agricultural applications where a reliable charging system is non-negotiable.
Constructed to Delco 10SI Series standards with internal regulator and external fan (IR/EF) configuration, the 7129N delivers 40 amperes at 24 volts with clockwise rotation — matching the output and direction requirements of the original equipment it replaces. Being supplied brand new, there is no remanufactured core to return and no uncertainty about service history.
The 7129N covers 51 applications across John Deere (35 applications), Case (13 applications) and Fiat-Allis (3 applications), including Case 680G Construction King, Case W14 and Case W18 series machines. John Deere fitment spans a broad range of agricultural and construction models; use the selection widget to match your exact make, model and engine variant.
