OEX Alternator 12V 110A Mitsubishi Style MXA315

The OEX MXA315 is a new 12V alternator rated at 110A, supplied in Mitsubishi style configuration and sold as each. It is listed with a twin leg alternator mount, internal regulator, AA pulley section, and a 60cc aluminium vac pump note, so matching the mounting and accessory layout matters before ordering.

This unit uses an 84mm pulley outside diameter, 55mm inside mounting legs, 11mm pivot hole diameter, M8 x 1.25 adjusting hole, and 183mm mount centre to centre. Those measurements are the key checks when comparing against the existing alternator in the vehicle.

OEX positions this alternator range as quality aftermarket rotating electrical equipment, with factories that are ISO9001 certified and a warranty stated as 3 years for passenger use and 1 year for commercial use. The listed part number is MXA315, and the pin code shown is IR49.

Application and Buying Notes

Before ordering, compare the part number MXA315 and the physical dimensions against the alternator already fitted to the vehicle. The important checks here are the 12V system, 110A output, twin leg mount, 55mm inside mounting legs, 11mm pivot hole, M8 x 1.25 adjusting hole, and 183mm centre-to-centre measurement.

The pulley details matter as well. This alternator is listed with an 84mm pulley outside diameter and AA pulley section, so the belt type and pulley layout need to align with the existing installation. If the vehicle uses a different pulley arrangement, that should be confirmed before purchase.

The note about a 60cc aluminium vac pump and adaptor suitability for HXK-32 and HXK-24 is also important. If the vehicle setup differs in vacuum pump style or adaptor requirement, the alternator may look similar but still be incorrect for the application.

OEX lists this as a new unit rather than remanufactured, and the warranty is stated separately for passenger and commercial use. That warranty wording should be read alongside the vehicle use case, especially where the alternator is being fitted to a work vehicle or commercial application.

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 MXA315 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.

For part number MXA315, 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.

Compatibility note: Confirm compatibility by checking the MXA315 part number, the 12V 110A specification, the twin leg mount, pulley measurements, and the specific vehicle application details before ordering.
