OEX Alternator 12V 75A Mitsubishi Style MXA226

The OEX MXA226 is a new 12V alternator rated at 75A, built in Mitsubishi style and supplied as an each unit for rotating electrical replacement work. It uses an internal regulator and a 5 groove pulley with a 69mm outside diameter, so the physical layout and drive setup should be checked carefully before ordering.

This alternator is listed with a twin leg mount, 175mm centre to centre mount spacing, 55mm inside mounting legs, an 8mm pivot hole and an M8 x 1.25 adjusting hole. Those measurements are the key checks for confirming whether the unit will suit the vehicle and bracket arrangement already in place.

OEX identifies this part as Part No. MXA226 and Pin Code IR49, with a weight of 5.4kg. The stated application support includes Mitsubishi and selected Hyundai models, so the part number and mounting dimensions should be matched against the original unit before fitment is attempted.

Application and Buying Notes

This alternator is designed around a 12V, 75A specification, so it is important to compare the charging output and physical mount details with the unit being replaced. The twin leg mount, 175mm centre to centre spacing, 55mm inside mounting legs and 69mm pulley diameter are all practical checkpoints that help determine whether the unit will physically line up.

The pulley section is 5 groove, which needs to match the belt system on the vehicle. If the belt arrangement, pulley offset or bracket style differs from the original alternator, the part may not suit even if the vehicle is shown in the fitment data. The internal regulator is also relevant when matching electrical setup.

OEX lists this as a new unit under Part No. MXA226, which is the safest reference to use when comparing against an existing alternator or parts catalogue. If you are working from an old part, check the pin code IR49, the 8mm pivot hole and the M8 x 1.25 adjusting hole before committing to the purchase.

The weight is listed at 5.4kg, which can be a useful comparison point when identifying whether the replacement is the same style as the original assembly. For mixed vehicle listings such as Mitsubishi and selected Hyundai applications, the correct model, year and engine arrangement should be confirmed against the vehicle, not assumed from the brand alone.

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 MXA226 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 75A Mitsubishi Style. Part number MXA226 should be checked first. Listed voltage is 12. Listed output rating is 75. 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 5 Groove. Those physical and electrical details should line up with the original unit before the replacement is approved for fitment.

For part number MXA226, 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 75 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Available application references include HYUNDAI LANTRA, HYUNDAI LANTRA 1991, HYUNDAI LANTRA 1992, HYUNDAI LANTRA 1993, MITSUBISHI 3000 GT, MITSUBISHI 3000 GT 1992. 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: Confirm fitment by matching Part No. MXA226, the Mitsubishi style mounting layout, the 12V 75A rating, and the listed measurements against the original alternator and vehicle application details before ordering.
