OEX Alternator 12V 70A Hitachi Style RXA015

The OEX Alternator RXA015 is a 12V, 70A remanufactured unit in Hitachi style, supplied as an alternator for rotating electrical applications. It uses an internal regulator and is listed with a twin leg alternator mount, with inside mounting legs measuring 81mm and a mount centre to centre dimension of 177mm.

This unit is specified with a 64mm pulley outside diameter and a 4 and 6 groove pulley section. The pivot hole diameter is 11mm and the adjusting hole is M8 x 1.25, so those mounting and drive details should be checked carefully against the original alternator before ordering.

The stated part number is RXA015, with pin code IR49 and a note that it suits Hitachi units. It is also noted as remanufactured and supplied with an adaptor to suit HXK-32 and HXK-24, which may be relevant where the existing setup uses those adaptor requirements.

Application and Buying Notes

Before buying, compare the RXA015 part number, Hitachi style design, and the physical dimensions against the unit being replaced. The most important checks here are the 12V system, 70A output, twin leg mount, 81mm inside mounting legs, 177mm mount centre to centre, and the 11mm pivot hole and M8 x 1.25 adjusting hole.

The pulley details also matter. This alternator uses a 64mm pulley with a 4 and 6 groove pulley section, so belt type and groove count need to match the vehicle’s existing setup. If the belt layout differs, the alternator may not be a direct replacement even if the general style looks similar.

Because this is a remanufactured alternator, it is sensible to inspect the mounting brackets, pulley alignment, plug arrangement, and any adaptor requirements before installation. The note advising an adaptor to suit HXK-32 and HXK-24 should be considered where the existing application depends on those parts.

The listed warranty is 3 years for passenger use and 1 year for commercial use. That warranty does not remove the need to confirm compatibility first, especially with alternators where the regulator type, mounting leg spacing, and pulley section all need to line up with the original component.

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 RXA015 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 70A Hitachi Style. Part number RXA015 should be checked first. Listed voltage is 12. Listed output rating is 70. 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 4 and 6 Groove. Those physical and electrical details should line up with the original unit before the replacement is approved for fitment.

For part number RXA015, 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 70 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Available application references include FORD CORSAIR, FORD CORSAIR 1989, FORD CORSAIR 1990, FORD CORSAIR 1991, NISSAN EXA, NISSAN EXA 1983. 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 the RXA015 part number, Hitachi style application details, 12V 70A rating, twin leg mount, mounting measurements, pulley specification, and any adaptor requirement before purchase.
