OEX Alternator 12V 110A Mitsubishi Style MXA2044

The OEX Alternator MXA2044 is a new 12V, 110A alternator built in a Mitsubishi style configuration. It is listed with a twin leg alternator mount, 80mm inside mounting legs, an 8.5mm pivot hole diameter, and an M8x1.25 adjusting hole. Those mounting details matter when you are checking replacement part matching, especially where the original unit has the same leg spacing and pulley arrangement.

This alternator is fitted with a 6 groove pulley with a 55mm outside diameter and clockwise rotation. A specific note applies to pulley use: for 5 groove applications, the rear 5 grooves on the pulley are used. That makes the pulley detail important to confirm before ordering, because the drive setup must suit the vehicle’s belt arrangement and accessory drive layout.

The unit is identified as OEX part number MXA2044 and pin code IR50. It is a 12 volt alternator rated at 110 amps, supplied new, and backed by a 3 year passenger / 1 year commercial warranty. For buyers comparing units, those electrical and mounting details are the key points to match rather than relying on appearance alone.

Application and Buying Notes

The most important checks on this alternator are the part number MXA2044, the 12V 110A electrical rating, and the mounting dimensions. The unit has 80mm inside mounting legs, a 175mm mount centre to centre measurement, an 8.5mm pivot hole and an M8x1.25 adjusting hole, so those dimensions should be compared carefully against the existing alternator before purchase.

Pulley and rotation details also need to match. This unit is supplied with a 6 groove pulley measuring 55mm outside diameter and it rotates clockwise. The note about using the rear 5 grooves for 5 groove applications is important, but it should only be relied on where the belt arrangement and pulley match the vehicle’s setup.

The alternator is described as a Mitsubishi style unit with an internal regulator and pin code IR50. Those identifiers are useful when comparing against the removed unit or a parts listing. If the existing alternator differs in mount style, regulator arrangement, pulley section or pin code, a visual match alone is not enough to confirm compatibility.

Fitment information supplied for this item references Subaru applications, including Forester, Impreza, Impreza WRX, Legacy, Liberty, Outback and Tribeca. Even with those references, buyers should still confirm the exact application against the vehicle and the original alternator details, because the practical match depends on the full set of electrical and mounting specifications.

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 MXA2044 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 MXA2044 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 MXA2044, 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.

Available application references include SUBARU FORESTER, SUBARU FORESTER 1998, SUBARU FORESTER 1999, SUBARU FORESTER 2000. 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 compatibility using OEX part number MXA2044, the Mitsubishi style designation, the 12V 110A rating, and the stated mounting and pulley measurements before ordering.
