OEX Alternator 12V 115A Mitsubishi Style MXA2004

The OEX Alternator MXA2004 is a new 12V unit with a 115A power rating, built in Mitsubishi style for applications that require this mounting and pulley arrangement. It is supplied as a single-leg alternator with an internal regulator, so the electrical and physical match need to be checked carefully against the vehicle or machine already fitted.

Key dimensions to confirm before ordering are the 56mm mount leg thickness, 156mm mount centre-to-centre, 10mm adjusting hole diameter, 10mm pivot hole diameter, and 50mm pulley outside diameter. The pulley is a 6 groove design and the shaft dimension is 17mm, which makes the replacement check more specific than voltage alone.

This alternator is listed as suitable for unit make Mando and is part number MXA2004. It weighs 6.92kg and is covered by a 3 year passenger / 1 year commercial warranty, giving buyers a clear reference point for both application matching and warranty context when replacing a worn charging unit.

Application and Buying Notes

Alternator replacement needs more than a matching voltage figure, so check the part number MXA2004 first, then compare the mounting pattern, pulley layout and regulator type against the unit being removed. This alternator is a 12V, 115A Mitsubishi style unit with a single-leg mount, so the fit needs to line up on both the electrical and mechanical side.

The mounting measurements matter here: 56mm mount leg thickness, 156mm centre-to-centre spacing, and 10mm adjusting and pivot holes. If those points do not match the existing alternator bracket and hardware, the unit may not sit correctly even if the vehicle appears in the application list.

Pulley alignment is another important check. This unit uses a 6 groove pulley with a 50mm outside diameter and a 17mm shaft dimension. Those details should be compared with the old alternator before purchase, particularly where the vehicle has been changed previously or where another charging unit has already been fitted.

The listed fitment applications include a wide range of passenger vehicles and equipment, from AUDI, BMW and MERCEDES-BENZ through to DYNAPAC machinery. That makes the application detail useful, but it is still best to confirm the exact engine or equipment version, belt setup and mounting style against the existing unit, not just the model name.

Because this alternator is specified as new and carries a 3 year passenger / 1 year commercial warranty, it is suited to buyers who want a direct replacement with clear warranty backing. As with any charging system part, the battery, belt condition and wiring should also be checked when diagnosing the fault, because a failed alternator is not always the only issue in the charging circuit.

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 MXA2004 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 115A Mitsubishi Style. Part number MXA2004 should be checked first. Listed voltage is 12. Listed output rating is 115. These details form the core reference points used by parts interpreters when confirming the correct replacement.

Mount style is Single 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 MXA2004, 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 115 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Available application references include AUDI 80, AUDI A4, AUDI A6, AUDI A6 2010, BMW 3, BMW 5. 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 number MXA2004, the 12V 115A specification, the single-leg mount, and the listed mounting and pulley dimensions against the alternator currently fitted to the vehicle or machine.
