OEX Alternator 12V 110A Mitsubishi Style MXA2031

The OEX Alternator MXA2031 is a 12V, 110A unit in Mitsubishi style, supplied as a new alternator for rotating electrical applications. It is listed with a twin leg alternator mount, 159mm centre-to-centre mounting, 45mm inside mounting legs, and a 10mm pivot hole diameter, so the mounting points need to match the vehicle application before purchase.

This alternator uses an internal regulator and a 6 groove pulley with a 66mm outside diameter. Those details matter because pulley section, pulley size, and regulator type all need to suit the charging system already fitted to the vehicle. The unit weighs 5.8kg and is supplied each.

OEX identifies this part under part number MXA2031, with pin code IR97 and a power rating of 110 amps. It is described as suitable for Mitsubishi applications, and the product is backed by a 3 year passenger / 1 year commercial warranty. That makes it important to confirm the exact fitment details as well as the electrical and mounting specifications before ordering.

Application and Buying Notes

Before ordering, match the part number MXA2031 and the physical mounting dimensions against the unit already fitted. The key checks here are the twin leg mount, 159mm mount centre-to-centre, 45mm inside mounting legs, 10mm pivot hole diameter, and 8mm adjusting hole diameter. If any of these differ, the alternator may not bolt up correctly even if the vehicle appears similar.

The electrical side also needs to line up with the vehicle’s charging system. This alternator is 12V with a 110A output and an internal regulator, so it should only be considered where those specifications suit the original application. Pulley style is equally important: this unit has a 6 groove pulley with a 66mm outside diameter, which must match the belt arrangement in the vehicle.

OEX lists this alternator as suitable for Mitsubishi applications, but fitment should still be confirmed against the existing unit and application details. The supplied fitment data in this listing is limited, so it is safer to verify by part number, mount style, pulley section, and regulator type rather than relying on the vehicle name alone. That is especially important when replacing an alternator that may have been superseded or changed during the vehicle’s life.

Because this is a new unit, it is intended as a replacement alternator rather than a remanufactured assembly. The unit weighs 5.8kg, which can also be a useful cross-check when comparing against the removed part. For warranty support, the coverage listed is 3 years for passenger use and 1 year for commercial use, so it is worth keeping purchase details and installation records.

If you are unsure, compare the old alternator side by side with this listing’s key identifiers: OEX, MXA2031, IR97, 12V, 110A, internal regulator, and 6 groove pulley. A careful match on those points gives the best chance of selecting the correct replacement and avoiding unnecessary downtime or returns.

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 MXA2031 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 MXA2031 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 6 Groove. Those physical and electrical details should line up with the original unit before the replacement is approved for fitment.

For part number MXA2031, 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 110 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Compatibility note: Confirm fitment with the existing alternator part number, mounting measurements, pulley section, and regulator type before purchase. Vehicle application should be checked against the actual unit fitted, as alternator specifications can vary within the same make or model range.
