OEX Alternator 12V 90A Mitsubishi Style MXA322

The OEX MXA322 is a new 12V alternator rated at 90A, listed as Mitsubishi style and suited to Mando applications. It is a rotating electrical component supplied as each, with an internal regulator and a twin leg alternator mount.

Key mounting details include 58mm inside mounting legs, a 172mm mount centre-to-centre measurement, an 8mm pivot hole diameter, and an M8 x 1.25 adjusting hole. The pulley outside diameter is 82mm with an A section belt profile, so matching the physical dimensions matters when comparing against the existing unit.

This alternator weighs 5.28kg and carries part number MXA322. OEX lists it under rotating electrical and notes it is backed by a 3yr passenger / 1yr commercial warranty, which is useful to confirm against how the vehicle or machine is used.

Application and Buying Notes

Before buying, compare the MXA322 against the unit already fitted and check the 12V system, 90A rating, and internal regulator arrangement. The physical details are just as important as the electrical rating, especially the 58mm inside mounting legs, 172mm mount centre-to-centre, and twin leg mount.

The pulley specification is another key checkpoint. This alternator uses an 82mm pulley with an A section belt profile, so the belt type and pulley alignment need to match the application. If the pulley or mounting pattern differs from the current part, it may not be a direct replacement.

Because the fitment list covers different machines and vehicles, it is wise to confirm by part number and application details rather than relying on a make name alone. The MXA322 reference, together with the Mando unit make and the listed mounting measurements, gives the most reliable way to verify compatibility.

For commercial use, the warranty term is listed separately as 1 year, while passenger use is listed as 3 years. If the alternator will be fitted to a machine or vehicle that sees heavier duty cycles, confirm the warranty expectation before purchase and keep the installation details on record.

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 MXA322 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 90A Mitsubishi Style. Part number MXA322 should be checked first. Listed voltage is 12. Listed output rating is 90. 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 A. Those physical and electrical details should line up with the original unit before the replacement is approved for fitment.

For part number MXA322, 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 90 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Available application references include BOBCAT 331, BOBCAT 331 2008, BOBCAT 331 2009, BOBCAT 331 2010, KIA SORENTO, KIA SORENTO 2007. Even with application listings, final confirmation should still be based on the exact unit being replaced and the service requirements of the vehicle or machine.

The listed warranty is 3yr Passenger 1yr Commercial. Warranty terms should be considered alongside correct application and part identification, as warranty does not replace fitment confirmation.

Compatibility note: Please confirm fitment using part number MXA322 and the listed application details, including 12V, 90A, internal regulator, twin leg mount, 58mm inside mounting legs, 172mm mount centre-to-centre, and 82mm A section pulley.
