OEX Alternator 12V 170A Mitsubishi Style MXA2079

The OEX MXA2079 is a new 12V alternator rated at 170A and built in Mitsubishi style for applications that match the listed mounting and pulley details. It uses an internal regulator, a twin leg alternator mount, and a 7 groove pulley with a 55mm outside diameter.

Key measurements matter with this unit: inside mounting legs are 80.5mm, mount centre to centre is 150mm, the pivot hole diameter is 8.5mm, and the adjusting hole diameter is 9mm. Those dimensions, together with the Part No. MXA2079 and Pin Code IR203, are the main points to check before ordering.

This alternator is supplied as a new rotating electrical unit and weighs 6.58kg. OEX notes that it suits Mitsubishi units, with a clear instruction to confirm by OE number, and that a 6 groove pulley version is available separately under MXA2126.

Application and Buying Notes

Before ordering, compare the Part No. MXA2079 and Pin Code IR203 with the original unit, because OEX specifically recommends confirming by OE number. That is the safest way to match this 12V 170A alternator to the correct Mitsubishi-style application without relying on appearance alone.

The pulley setup needs close attention. This alternator is listed with a 7 groove pulley and a 55mm outside diameter, and OEX states that if you need a 6 groove pulley version, MXA2126 is the alternate option. Pulley groove count and diameter must match the drive belt system on the vehicle.

Mounting dimensions are just as important as electrical rating. Check the twin leg mount, 80.5mm inside mounting legs, 150mm mount centre to centre, 8.5mm pivot hole, and 9mm adjusting hole before purchase. Even a small difference in these measurements can prevent installation or alignment.

The 170A output and internal regulator suit applications designed for this specification, but output alone is not enough to confirm fitment. The alternator must also match the OE number, mount style, pulley section, and physical measurements listed here. If any of those details differ, the unit may not be the correct choice.

This is a new unit with a 3yr Passenger and 1yr Commercial warranty, so it is suitable for buyers wanting a replacement rather than a repairable core. As with any alternator, correct fitment and charging performance depend on matching the vehicle’s original specification, belt layout, and electrical requirements.

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 MXA2079 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 170A Mitsubishi Style - See Note. Part number MXA2079 should be checked first. Listed voltage is 12. Listed output rating is 170. 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 7 Groove. Those physical and electrical details should line up with the original unit before the replacement is approved for fitment.

For part number MXA2079, 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 170 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Available application references include SUBARU FORESTER, SUBARU FORESTER 2008, SUBARU FORESTER 2009, SUBARU FORESTER 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.

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: Confirm fitment using the OE number, Part No. MXA2079, mounting dimensions, and pulley details before ordering. If the vehicle requires a 6 groove pulley, use MXA2126 instead.
