Alternator for Massey Ferguson Compact Tractors

MF1030, MF1035, MF1040, MF1045, MF205, MF210, MF220 - 12V 35A IR/EF

This alternator is built to OEM specifications as a direct fit and function replacement for the Hitachi LR135-series unit fitted to Massey Ferguson compact tractors, as well as Gehl and Isuzu industrial equipment using the same charging system. It is an IR/EF unit - internally regulated with an external fan - rated at 12 volts and 35 amps.

The unit rotates clockwise (CW) and uses a single-groove (V1) pulley, matching the original factory configuration so it fits straight into place without modification. It replaces Massey Ferguson 3282-883-M91 and Hitachi LR135-58, LR135-58B and LR135-126 directly.

Frequently Asked Questions

Will this alternator fit my tractor without modification?

Yes. This is a direct OEM-fit replacement built to the same specification (12V, 35A, IR/EF, CW rotation, V1 pulley) as the original unit, so no modification is required.

What's included with this part?

You receive the alternator unit only. Mounting hardware, brackets and pulleys are not included unless already fitted to the original unit you are replacing.

How can I tell my old alternator has failed?

Common signs include a warning light staying on, dimming or flickering lights, a dead or slowly draining battery, unusual whining noises, or the engine stalling when electrical accessories are switched on.

What does IR/EF mean?

IR/EF stands for Internally Regulated, Externally Fan-cooled - the voltage regulator is built into the alternator body and cooling air is drawn in by an external fan rather than through the housing.
