OEX Alternator 12V 100A Mitsubishi Style MXA2118

The OEX MXA2118 is a new 12V alternator rated at 100A, built in a Mitsubishi style with a twin leg alternator mount. It uses an internal regulator and a 6 groove pulley, with a pulley outside diameter of 55mm.

This unit is listed with an inside mounting leg measurement of 67mm, a mount centre to centre measurement of 169mm, a pivot hole diameter of M10x1.25 / 10, and an adjusting hole diameter of M10x1.25. Those dimensions matter when you are comparing brackets, mounts, and belt alignment before ordering.

OEX positions this alternator within its rotating electrical range, and the brand notes ISO9001 certified manufacturing sources. It is covered by a 3 year passenger / 1 year commercial warranty, which is a useful reference point for buyers who want a new replacement rather than a remanufactured unit.

Application and Buying Notes

Before buying, match the part number MXA2118 against your existing alternator details and confirm the mounting style. This unit is a Mitsubishi style alternator with twin leg mounting, so the inside mounting legs measurement of 67mm and the 169mm mount centre to centre measurement should be checked against the vehicle side hardware, not assumed.

The pulley details also need attention. This alternator has a 55mm outside diameter pulley with a 6 groove section, so the belt type and pulley arrangement need to align with the vehicle application. If the belt profile or groove count does not match, the unit may not be suitable even if the electrical rating is correct.

Electrical output is rated at 100A at 12V, which is the key operating specification for charging system replacement work. The internal regulator is another important checkpoint, because regulator style must suit the system the alternator is being fitted to.

The listed fitment preview mentions Mazda and Mazda 2 applications, including Mazda 2 model years from 2007 through 2014, but that preview should still be cross-checked carefully against the part number, mounting dimensions, and pulley configuration before purchase. Variations can occur across engines and charging system layouts.

Because this alternator is new and sold individually as each, it is sensible to compare your original unit’s measurements, connector arrangement, and mount type before fitting. That approach helps avoid delays and reduces the chance of ordering the wrong charging component for the vehicle.

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 MXA2118 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.
