Alternator for Ford Backhoe & Massey Ferguson 12V 70A Lucas A127 Type
Ford Backhoe & Massey Ferguson - 12-Volt 70 Amp - Lucas A127 Pattern
This alternator is built to OEM specifications as a direct fit and function replacement for Ford Backhoe and Massey Ferguson machines fitted with a 12-volt IR/EF charging system. It uses the original single-groove V-belt pulley with a 74mm outside diameter and the same mounting arrangement, so no modification is required.
Rated at 70 amps with an internally regulated (IR), externally fan-cooled (EF) design and clockwise rotation, this unit follows the Lucas A127 pattern and matches the output and specification of the original alternator it replaces. The regulator sits at the 5 o'clock clock position and the B+ output stud is an M6 x 1.00 thread, negative earth.

Frequently Asked Questions
Will this alternator fit without modification?
Yes. It uses the same mounting, connector and pulley arrangement as the original alternator, so no drilling or wiring changes are needed.
What's included when I order this part?
You receive one fully assembled replacement alternator, ready to bolt on and wire in place of your existing unit.
How can I tell my alternator has failed?
Common signs are a battery warning light on the dash, dimming or flickering lights, a battery that won't hold charge, or a whining/grinding noise from the alternator itself.
How do I confirm this is the right unit for my machine?
Check the Lucas or Massey Ferguson number stamped on your original unit against the cross reference table above, or match the Lester 12096 / PIC 280-327 reference and the 74mm pulley diameter.
