This 12-volt, 120-amp alternator is built to OEM specifications for Case and New Holland tractors from 2003 onward. It uses the internally regulated (IR) design fitted as standard on these tractors.
The unit is fitted with an 8-groove pulley at 67mm outside diameter, matching the original fitment exactly, so it bolts straight in as a fit-and-function replacement with no wiring or bracket changes required. The internally regulated design keeps the wiring loom identical to the factory alternator it replaces.
