OEX Alternator 12V 65A Mitsubishi Style RXA287

The OEX Alternator RXA287 is a 12V, 65A remanufactured alternator in Mitsubishi style, supplied as unit type ALTERNATOR with part number RXA287 and pin code IR20. It is listed with an internal regulator and a twin leg alternator mount, so matching the physical mounting pattern is just as important as matching the electrical rating.

Key mounting measurements for this unit are 66mm inside mounting legs, 175mm mount centre to centre, a 10.2mm / M10 x 1.25 pivot hole diameter, and an M8 x 1.0 adjusting hole diameter. The pulley is a 73mm A section pulley, which is a useful check when comparing against the unit already fitted to the vehicle.

This alternator suits Mitsubishi unit make and is shown against a range of Ford, Hyundai and Mazda applications in the fitment data provided. Because alternators can vary by bracket style, pulley setup and regulator arrangement, the safest approach is to confirm the part number RXA287 and compare the mounting and pulley details before ordering.

Application and Buying Notes

Before buying, compare the alternator already in the vehicle with the RXA287 mounting pattern and pulley details. The listed measurements of 66mm inside mounting legs, 175mm mount centre to centre, 10.2mm / M10 x 1.25 pivot hole diameter, and M8 x 1.0 adjusting hole diameter are the most practical checks for fitment on the vehicle side.

The 12V, 65A rating tells you the electrical output and system voltage, but it does not override mechanical fitment. A 73mm A section pulley, internal regulator and twin leg mount need to line up with the existing installation, otherwise the alternator may not bolt up or may not suit the drive belt arrangement.

This unit is listed as Mitsubishi style and suits Mitsubishi unit make, with applications shown for Ford, Hyundai and Mazda vehicles. Those application references are useful starting points, but matching by part number RXA287 and confirming the physical dimensions remains the better buying check, especially on older vehicles where alternator changes may have been made previously.

The OEX alternator is remanufactured and carries a 3yr Passenger / 1yr Commercial warranty. Warranty terms are worth noting, but they do not replace application verification. If your original alternator differs in regulator type, pulley section, or mounting ear spacing, compare carefully before placing the order.

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 RXA287 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 RXA287, 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 65 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Available application references include FORD CAPRI, FORD CAPRI 1989, FORD CAPRI 1990, FORD CAPRI 1991, HYUNDAI EXCEL, HYUNDAI EXCEL 1990. 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: Please confirm compatibility using part number RXA287, the 12V 65A rating, internal regulator setup, twin leg mount, and the listed mounting and pulley measurements before purchase. Vehicle applications are provided as guidance only and should be checked against the alternator currently fitted to the vehicle.
