OEX Alternator 12V 110A Mitsubishi Style MXA2040

The OEX Alternator MXA2040 is a 12V, 110A unit in Mitsubishi style, supplied as a new alternator for rotating electrical applications. It is listed with a 7 groove pulley, internal regulator, and twin leg alternator mount, so the key installation checks are the mounting style, pulley setup, and electrical system requirements.

This unit suits Mitsubishi and is also shown against Mitsubishi 380, Mitsubishi Pajero, Mitsubishi Triton, Subaru, and Subaru Forester applications in the supplied fitment data. Because alternator fitment can vary by engine, bracket design, and wiring layout, the part number MXA2040 and the measured mounting details should be checked carefully before ordering.

Important physical specifications include 55mm inside mounting legs, M10x1.25 / 10 pivot hole diameter, M8x1.25 adjusting hole diameter, and 177mm mount centre to centre. The pulley outside diameter is 58mm, the unit weighs 5.54kg, and the pin code is IR70.

OEX lists this alternator with a 3 year passenger and 1 year commercial warranty. It is a brand-new unit, not remanufactured, and is part of the rotating electrical product group.

Application and Buying Notes

The most important checks on this alternator are the MXA2040 part number, the 12V system requirement, and the 110A output rating. If your vehicle uses a Mitsubishi style alternator, the 7 groove pulley, internal regulator, and twin leg mount must also line up with the original unit before fitment.

The mounting dimensions are specific: 55mm inside mounting legs, 177mm mount centre to centre, M10x1.25 / 10 pivot hole diameter, and M8x1.25 adjusting hole diameter. These measurements help confirm whether the alternator will physically mount to the bracket and adjust correctly in place.

This alternator weighs 5.54kg and uses a 58mm pulley outside diameter. Those details are useful when comparing against the old unit, especially if there have been previous repairs, pulley changes, or bracket differences. Matching the pulley section and regulator type is just as important as matching the casing shape.

The supplied fitment information includes Mitsubishi, Mitsubishi 380, Mitsubishi Pajero, Mitsubishi Triton, Subaru and Subaru Forester applications, but those names alone are not enough to confirm compatibility. Engine variant, year, and charging system layout can change the required alternator, so compare the existing unit carefully before ordering.

If you are replacing a faulty alternator, check the label on the old unit and compare the part number MXA2040, the pin code IR70, and the visible connector and mount arrangement. A close visual match is helpful, but the safest approach is to verify the part number and all key measurements against the vehicle already fitted.

For workshop or trade use, the warranty coverage is listed as 3 years for passenger use and 1 year for commercial use. That does not replace fitment verification, but it does provide a clear reference point for the intended application type when matching the alternator to the vehicle and duty cycle.

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 MXA2040 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.

OEX Alternator 12V 110A Mitsubishi Style. Part number MXA2040 should be checked first. Listed voltage is 12. Listed output rating is 110. These details form the core reference points used by parts interpreters when confirming the correct replacement.

Mount style is Twin Leg. Regulator type is Internal. Pulley configuration is 7 Groove. Those physical and electrical details should line up with the original unit before the replacement is approved for fitment.

For part number MXA2040, 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.

Compatibility note: Confirm fitment by checking the MXA2040 part number, 12V / 110A rating, Mitsubishi style casing, twin leg mount, 7 groove pulley, and all mounting measurements against the vehicle’s original alternator before purchase.
