Alternator for Case, Ford & New Holland Tractors
Case, Ford & New Holland tractors, skid steers and front mowers
This replacement alternator is built to OEM specifications for Case, Ford and New Holland machines produced between 1987 and 2002, and is also the correct unit for later New Holland LS-series skid steer loaders, TC-series compact tractors and MC-series front mowers. It is a direct fit and function replacement for the original unit, restoring reliable charging output without any modification to the existing wiring or mounting points.
It replaces the SBA18504-6320 / 18504-6320 unit and the Mitsubishi A7T03877 original. The alternator uses a single-groove V-belt pulley (V1), an internal fan (IF) and an internal regulator (IR), matching the specification of the original equipment fitted by the machine manufacturer, and rotates clockwise (CW), the same direction as the alternator it replaces.

What is included?
You receive one new alternator, ready to install using your existing bracket, belt and wiring loom.
How can I tell my old alternator has failed?
Common signs include a battery warning light, dim or flickering lights, a battery that won't hold charge, or a whining or growling noise from the alternator itself.
