Product Number: 12143N
Find the right Starter Motor & Alternator for your Machine
Starter Motor & Alternator FinderThe WAI 12143N is a brand-new 12V 65A alternator. It is built to Lucas IR/EF specification, replacing original-equipment numbers from Ford, Lucas, Delco Remy, Valeo, Iskra, and Case across 33 confirmed applications. It is a direct-fit replacement for agricultural and plant machinery where the original Lucas unit has worn or failed.
Constructed to IR/EF (internal regulator, external fan) design, the 12143N delivers a clockwise-rotation output of 65 amperes at 12 volts — matching the electrical demands of the vehicles it serves. The unit is supplied without a pulley, so the original pulley is retained during installation, keeping the job straightforward for workshop and field-side technicians alike.
Fitment spans Valtra Valmet (22 applications), Case (6 applications), Massey Ferguson (3 applications) and New Holland Industrial (2 applications), including Case 1294, 1394, 1494, 1594, 1690 and 1694, and Massey Ferguson MF-360 and MF-390. Cross-references include Ford 6173461, Lucas 24049, Lucas 24049A, Lucas 24049D, Delco Remy DRA3940, Valeo 2929190, Valeo 432864, Iskra AAK4118, Iskra IA0276, Case K307720, and Massey Ferguson 3477851M91, among 25 verified references in total.
