OEX Alternator 12V 110A Mitsubishi Style MXA291

The OEX Alternator MXA291 is a new 12V, 110A unit in Mitsubishi style, supplied as an each item for rotating electrical replacement work. It uses an internal regulator, a 6 groove pulley, and a twin leg alternator mount, so matching the physical mount and pulley layout is just as important as matching the electrical rating.

Key dimensions for checking against the original unit include 55mm inside mounting legs, 178mm mount centre to centre, an 8mm pivot hole diameter, and an M8 x 1.25 adjusting hole. The pulley outside diameter is 70mm, and the unit weighs 6.3kg, which can help when comparing against the alternator already in the vehicle.

This alternator is listed under part number MXA291 and suits Mitsubishi applications, with fitment data also showing Hyundai Lantra and Hyundai Sonata references. Because alternators are model and engine specific in many cases, the safest approach is to compare the part number, mount style, pulley type, and the vehicle application details before ordering.

Application and Buying Notes

Before ordering, compare the alternator currently fitted to the vehicle with the MXA291 mounting and drive details. The important checkpoints here are the 12V system, 110A output, twin leg alternator mount, 6 groove pulley, 70mm pulley outside diameter, and the 178mm mount centre to centre measurement.

The listed fitment data includes Mitsubishi, Mitsubishi 3000 GT, Mitsubishi GTO, Mitsubishi Pajero, Hyundai Lantra, and Hyundai Sonata references, but alternator fit can still vary by engine, build date, and accessory setup. The safest confirmation is to match the part number MXA291 and check the physical dimensions against the old unit before the vehicle is taken apart.

If the original alternator has a different mounting ear spacing, pivot hole size, or pulley style, it may not be the correct replacement even if the vehicle appears in the application list. The 55mm inside mounting legs, 8mm pivot hole diameter, and M8 x 1.25 adjusting hole are practical checks that can prevent ordering the wrong part.

This is a new alternator, not a remanufactured unit, and it carries a 3yr Passenger / 1yr Commercial warranty. That warranty period is useful for identifying the intended use case, but it does not replace fitment checking. Always confirm the vehicle application, regulator type, and pulley configuration before installation.

For workshop use, the 6.3kg weight and internal regulator are also worth noting when planning the job. A direct physical comparison with the existing unit is the most reliable way to confirm whether MXA291 is the correct replacement for the vehicle being repaired.

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 MXA291 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.

Relevant published details for this unit include Type ALTERNATOR, Unit of Measure EACH, Warranty 3yr Passenger 1yr Commercial, Inside Mounting Legs 55mm, Pivot Hole Diameter 8, Pulley Outside Diameter 70mm, Regulator Type Internal, Voltage 12, Mount Cnt to Cnt 178mm, Weight 6.3kg.

Additional published details for cross-checking include Product Group 1 ROTATING ELECTRICAL, Part No. MXA291, Brand OEX, Description OEX Alternator 12V 110A Mitsubishi Style, Adjusting Hole Diameter M8 x 1.25, Pin Code IR49, Power Rating (Amp) 110, Pulley Section 6 Groove, Suits Unit Make Mitsubishi, Alternator Mount Twin Leg.

OEX Alternator 12V 110A Mitsubishi Style. Part number MXA291 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 MXA291, 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 HYUNDAI LANTRA, HYUNDAI LANTRA 1995, HYUNDAI LANTRA 1996, HYUNDAI LANTRA 1997, MITSUBISHI 3000 GT, MITSUBISHI 3000 GT 1992. 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 part number MXA291, the 12V 110A specification, the twin leg mount, and the measured mounting and pulley details before ordering or fitting.
