OEX Alternator 12V 90A Mitsubishi Style MXA2090

The OEX Alternator MXA2090 is a 12V, 90A unit in Mitsubishi style, supplied as a new alternator for rotating electrical applications. It uses an internal regulator, a 4 groove pulley, and twin leg alternator mounting, with inside mounting legs measured at 75mm.

This alternator is listed with a Mount Cnt to Cnt of 171mm, an M8x1.25 adjusting hole, and a 10mm pivot hole. The pulley outside diameter is 62.5mm and the unit weight is 5.48kg, so it is important to compare the physical dimensions with the vehicle’s original alternator before ordering.

OEX identifies this unit under part number MXA2090, with product group listings for Alternators and Rotating Electrical. The warranty is 3 years for passenger use and 1 year for commercial use, which is a useful point to check alongside the fitment details for the vehicle being serviced.

Application and Buying Notes

Before ordering, confirm the existing alternator matches the key identifiers on this unit: MXA2090, 12V, 90A, Mitsubishi style, twin leg mount, and internal regulator. Even small differences in mounting style or pulley layout can prevent a direct swap, so the 75mm inside mounting legs and 171mm centre-to-centre measurement should be checked against the vehicle.

The pulley specification matters as much as the electrical rating. This alternator uses a 4 groove pulley with a 62.5mm outside diameter, so the belt system on the vehicle must be matched to that setup. If the original unit uses a different groove count, pulley size, or belt alignment, the alternator may not suit without further comparison.

Fitment is listed for GREAT WALL SA220, including 2009 and 2010 applications, but the safest buying step is still to compare the physical dimensions and part number before purchase. The supplied vehicle names help narrow the application, while the measurements confirm whether the alternator will actually mount and run correctly in place of the existing unit.

For commercial use, the warranty term is 1 year, while passenger use is covered for 3 years. That distinction is worth noting if the vehicle is used for work, delivery, or fleet service, because warranty coverage depends on how the unit is used as well as whether the correct alternator is installed.

When replacing an alternator, it is sensible to inspect the condition of the belt, wiring connections, and mounting hardware at the same time. A new alternator such as this OEX MXA2090 will still rely on the vehicle’s charging circuit, so worn connectors, damaged wires, or incorrect belt tension can affect how the system performs once fitted.

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 MXA2090 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 MXA2090 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 4 Groove. Those physical and electrical details should line up with the original unit before the replacement is approved for fitment.

For part number MXA2090, 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 GREAT WALL SA220, GREAT WALL SA220 2009, GREAT WALL SA220 2010. 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.

Compatibility note: Please confirm compatibility using part number MXA2090, the Mitsubishi style design, and the recorded mounting and pulley measurements before purchase. Vehicle fitment should be checked against the exact application and the existing alternator on the vehicle.
