Product Number: 12129N
The WAI 12129N is a brand-new 12V 35A alternator. It is built to the Hitachi IR/EF design, supplying the electrical system on a range of agricultural tractors. It replaces Hitachi original-equipment units including LR135-58, LR135-58B, GD204296A and GD204296-A, as well as Bosch Exchange 0986034311 and Delco Remy DRA4311, covering 16 OE cross-references in total.
The unit features a clockwise rotation and a groove pulley, matching the original Hitachi specification precisely. Being supplied brand new rather than remanufactured means no core charge and no worn internals to contend with — the alternator arrives ready to install.
Fitment covers 15 applications across Massey Ferguson, Allis Chalmers and Deutz-Allis tractors, including the Massey Ferguson MF-1030, MF-1035, Allis Chalmers 5015 and 5020, and Deutz-Allis 5220 and 5230. Use the selection widget or search by OE number to confirm your specific model.
