OEX Alternator 12V 100A Mitsubishi Style MXA325

The OEX Alternator MXA325 is a 12V, 100A unit in Mitsubishi style, supplied new as an alternator for rotating electrical applications. It is listed with an internal regulator, a 6 groove pulley section, and a twin leg alternator mount, so those key physical details are important when matching it to the vehicle and the existing setup.

This unit carries a 52mm pulley outside diameter, 68mm inside mounting legs, an M10x1.25 / 10 pivot hole diameter, and an 11mm adjusting hole diameter. The mount centre to centre measurement is 174mm, and the alternator weighs 5.32kg, which are all useful checks when comparing the replacement to the original unit already fitted to the vehicle.

OEX identifies this alternator as part number MXA325, pin code IR49, with a power rating of 100 amps at 12 volts. It is backed by a 3 year passenger and 1 year commercial warranty, which gives buyers a clear warranty benchmark when assessing the purchase for private or trade use.

The listed brand application is Mitsubishi, and the product is described as Mitsubishi style rather than a universal replacement. That makes the part number, mounting layout, pulley section, and electrical specification the safest reference points before ordering.

Application and Buying Notes

When replacing an alternator, the safest approach is to compare the existing unit against the listed details rather than relying on appearance alone. The MXA325 is a Mitsubishi style alternator with a twin leg mount, 12V system voltage, and 100A output, so the electrical and mounting details both matter.

The pulley and bracket measurements are especially important here. A 6 groove pulley section, 52mm pulley outside diameter, 68mm inside mounting legs, and 174mm mount centre to centre need to line up with the vehicle’s original arrangement if you want a straightforward installation.

The internal regulator is another point to confirm before purchase. If the vehicle or charging system is set up for a different regulator type, the alternator may not be a direct swap even if the physical mount looks close, so it is worth checking the original part number, plug arrangement, and mounting points carefully.

This alternator is listed as new and carries a 3 year passenger and 1 year commercial warranty. That does not replace fitment checking, but it does give a clear warranty context for private or trade use once the part number MXA325 and application details have been confirmed.

Before supply, the safest approach is to confirm the original unit details against the listed part number, voltage, output rating, mounting arrangement, and pulley configuration. That checking process is standard practice in the parts trade because visually similar units can still differ in service-critical ways.

For workshop, fleet, and equipment applications, accurate identification of part number MXA325 helps avoid unnecessary freight, additional labour, and vehicle or machine downtime. Where the application is not straightforward, the original unit, OEM reference, or workshop records should be used as the primary confirmation point.

For part number MXA325, the normal identification sequence is part number, electrical rating, mounting arrangement, connector or terminal style, and pulley or drive details. Using those checkpoints helps confirm that the listed unit matches the service requirement rather than only looking similar.

For a alternator in workshop, fleet, trade, agricultural, or construction service, the listed voltage 12 and output 100 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Compatibility note: Please confirm compatibility using the part number MXA325, pin code IR49, and the exact mounting and pulley measurements from your original alternator before ordering. Fitment is only confirmed here for Mitsubishi style application details supplied, so the vehicle should be checked carefully against the listed specifications.
