OEX Alternator 12V 70A Denso Style RXA448

The OEX Alternator RXA448 is a 12V, 70A remanufactured unit built in a Denso style with an internal regulator and a single-leg alternator mount. It is supplied as an each item and carries a 5kg weight, which is useful when comparing against the original unit during replacement.

Key mounting details include a 160mm mount centre-to-centre distance, 58mm mount leg thickness, a 10mm pivot hole diameter, and an M8 x 1.25 adjusting hole. The pulley is a 5 groove design with a 74mm outside diameter, so these dimensions should be checked carefully against the vehicle’s existing alternator and belt setup.

This alternator is listed under OEX part number RXA448 and is identified as suited to Denso units. It sits within the rotating electrical group and is backed by a 3 year passenger / 1 year commercial warranty, which is an important consideration for buyers who want a remanufactured replacement with defined support terms.

Application and Buying Notes

Before buying, match the vehicle’s original alternator to the RXA448 part number, because the key identifiers here are 12V, 70A, Denso style, internal regulator, and single-leg mount. The pulley is a 5 groove unit with a 74mm outside diameter, so belt alignment and groove count need to be checked against the existing setup, not assumed from the vehicle badge alone.

The physical measurements are just as important as the electrical rating. This unit has a 160mm mount centre-to-centre distance, 58mm mount leg thickness, 10mm pivot hole diameter, and an M8 x 1.25 adjusting hole. If any of those points differ from the alternator coming off the vehicle, the part may not line up correctly even if the vehicle is listed elsewhere.

Because this is a remanufactured alternator, it is sensible to inspect the existing wiring plug, regulator arrangement, mounting ears, and pulley section before fitting. The product is designed for Denso-style applications, so a close visual comparison with the original alternator is worthwhile when the vehicle has had previous repairs or component swaps.

The warranty is 3 years for passenger use and 1 year for commercial use, which gives a clear reference point for the intended application. That warranty does not replace the need to confirm compatibility, especially on older vehicles where alternator styles, pulleys, and mounts may have been changed over time.

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 RXA448 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 Denso Style. Part number RXA448 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 Single Leg. Regulator type is Internal. Pulley configuration is 5 Groove. Those physical and electrical details should line up with the original unit before the replacement is approved for fitment.

For part number RXA448, 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 HONDA ACCORD, HONDA ACCORD 1985, HONDA ACCORD 1986, HONDA ACCORD 1987. 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 with the RXA448 part number, Denso-style application, 12V 70A rating, single-leg mount, and the listed dimensions before purchasing. Vehicle listings can vary, so the safest approach is to compare the original unit and mounting details carefully.
