Alternator for Massey Ferguson MF-231 & MF-261 Tractors

12-Volt 44 Amp IR/EF - Perkins AD3-152 & AD4-236 Diesel

This alternator is built to OEM specifications as a direct fit-and-function replacement for the alternator fitted to Massey Ferguson MF-231 and MF-261 tractors with Perkins AD3-152 and AD4-236 diesel engines. It bolts onto the original mounting points using the factory single-groove pulley.

It is a 12-volt, 44-amp unit with an internal regulator (IR) and external fan (EF), running on a 1-V pulley with a 1/2 inch belt and an M6 x 1.0 B+ output terminal, matching the original Massey Ferguson fitment. This is the later internally regulated version - some modification may be required if you are replacing an earlier externally regulated alternator.

How do I confirm this is the right unit for my tractor?

Check the Massey Ferguson number 1075-447-M91 or 7003-559-M1 on your original alternator, or match the Elmot/Marelli A124-44A reference.

How do I know my old alternator has failed?
