OEX Alternator 12V 130A Mitsubishi Style MXA2102

The OEX Alternator MXA2102 is a new 12V, 130A unit with a Mitsubishi-style design, built for rotating electrical applications where the mounting and pulley setup must line up correctly. It uses a twin leg alternator mount, 80mm inside mounting legs, and an internal regulator, so it is important to compare the physical dimensions and connector arrangement before ordering.

This alternator is supplied as an each unit and features a 6 groove pulley with a 52mm outside diameter. The pivot hole diameter is listed as 9 / M8, the adjusting hole diameter is 9, and the mount centre to centre measurement is 152mm. Those figures matter when you are checking whether the unit will physically sit and tension correctly in the vehicle.

OEX identifies this part as part number MXA2102. It is a 12 volt alternator rated at 130 amps and weighs 5.95kg. The unit carries a 3 year passenger / 1 year commercial warranty, which gives a clear reference point for the intended use category, but the key buying step is still confirming the part number and mounting details against the vehicle application.

Application and Buying Notes

The main fitment check for this OEX alternator is the part number MXA2102, together with the physical mounting dimensions: twin leg mount, 80mm inside mounting legs, 152mm mount centre to centre, 9mm adjusting hole, and 9 / M8 pivot hole. If any of those measurements differ from your original unit, the alternator may not mount or tension correctly.

The pulley specification is also important. This unit uses a 6 groove pulley with a 52mm outside diameter, so the belt profile must match what the vehicle requires. A pulley that does not match the existing belt arrangement can cause noise, belt wear, or installation issues, even if the alternator otherwise looks similar.

Because this is a Mitsubishi-style alternator, it should be checked carefully against the vehicle’s existing alternator rather than assumed to suit by appearance alone. The listing also shows Subaru in fitment data, including Forester and Liberty applications, but those applications should still be confirmed against the exact part number and measurements before purchase.

The 130A output, 12V system, and internal regulator make this a straightforward electrical match only when the vehicle specification is the same. If you are replacing an alternator, compare the original unit’s regulator type, mount style, pulley section, and physical dimensions so the replacement is correct for the charging system and belt drive setup.

Warranty cover is listed as 3 years for passenger use and 1 year for commercial use. That is useful when comparing ownership conditions, but it does not replace the need to confirm fitment. In automotive electrical parts, the safest approach is to verify the part number, mount style, pulley layout, and measured dimensions before fitting or ordering.

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 MXA2102 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 130A Mitsubishi Style. Part number MXA2102 should be checked first. Listed voltage is 12. Listed output rating is 130. 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 MXA2102, 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 130 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Compatibility note: Please confirm compatibility using part number MXA2102, the Mitsubishi-style application, and the listed mounting and pulley dimensions before purchase. If the original alternator does not match the twin leg mount, 80mm inside mounting legs, 152mm centre-to-centre measurement, or 6 groove pulley setup, do not assume it will fit.
