OEX Alternator 12V 160A Mitsubishi Style MXA2111

The OEX Alternator MXA2111 is a 12V, 160A unit in Mitsubishi style, supplied as a new alternator for rotating electrical applications. It is listed with a 6 groove pulley, external regulator, and twin leg alternator mount, so the mounting layout and regulator arrangement are important checks before purchase.

This alternator uses an inside mounting leg measurement of 55mm, a pivot hole diameter of M10x1.5/11, and an adjusting hole diameter of 11.5mm. The pulley outside diameter is 53mm, and the unit weighs 5.94kg, which can help when confirming a match against the existing component.

OEX identifies this part with part number MXA2111 and pin code ER55. It is backed by a 3 year passenger / 1 year commercial warranty, and it is described as a Mitsubishi style alternator with 160 amp output for 12V systems.

Application and Buying Notes

Before ordering, compare the part number MXA2111 and pin code ER55 against the alternator already fitted to the vehicle. The alternator is a Mitsubishi style unit with a 12V, 160A specification, so the replacement needs to match both the electrical output and the mounting style, not just the general appearance.

The physical checks matter just as much as the electrical ones. This unit has a 6 groove pulley, 53mm pulley outside diameter, 55mm inside mounting legs, M10x1.5/11 pivot hole diameter, 11.5mm adjusting hole diameter, and a twin leg mount. Those measurements need to line up with the bracket, belt and wiring arrangement already on the vehicle.

The supplied fitment preview points to BMW 5 and FIAT FREEMONT applications, including BMW 5 1985 to 1987 and FIAT FREEMONT 2011 to 2016. Even when a model appears in the fitment list, confirm the existing alternator details on the vehicle because alternators can vary by engine, electrical system and mount configuration.

This is a new alternator, not a remanufactured unit, and it carries a 3 year passenger / 1 year commercial warranty. Warranty coverage is useful, but it does not replace the need to confirm the voltage, amperage, regulator type and mounting dimensions before fitting.

If the original alternator uses a different regulator arrangement, pulley section, or mounting measurement, the part may not be suitable even where the vehicle model looks close. A direct comparison with the removed unit is the safest way to avoid downtime and unnecessary returns.

For workshop or trade use, it is worth checking the vehicle’s charging system details alongside the part number MXA2111. Matching the 12V system, 160A output, external regulator and twin leg mount is the most reliable way to narrow the choice to the correct alternator.

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 MXA2111 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 160A Mitsubishi Style. Part number MXA2111 should be checked first. Listed voltage is 12. Listed output rating is 160. These details form the core reference points used by parts interpreters when confirming the correct replacement.

Mount style is Twin Leg. Regulator type is External. 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 MXA2111, 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 160 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Available application references include BMW 5, BMW 5 1985, BMW 5 1986, BMW 5 1987, FIAT FREEMONT, FIAT FREEMONT 2011. 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 by matching part number MXA2111, pin code ER55, and all mounting and electrical details against the vehicle and removed alternator before ordering.
