OEX Alternator 12V 60A Denso Style RXA402

The OEX Alternator RXA402 is a 12V, 60A remanufactured alternator built in a Denso style configuration. It is specified with an internal regulator, a 3 groove pulley with 64mm outside diameter, and a single leg alternator mount, so those details should be checked against the original unit before purchase or installation.

This unit is identified as part number RXA402 and is suited to Denso applications. Key mounting dimensions include 58mm mount leg thickness, 164mm mount centre-to-centre, a 10mm pivot hole diameter, and an M8 x 1.25 adjusting hole. Those measurements are the main checkpoints when comparing it to the alternator being replaced.

OEX lists this alternator as part of its rotating electrical range and supplies it as an each item at 4.6kg. It carries a 3 year passenger / 1 year commercial warranty, which is useful to note when choosing between a replacement alternator for private use and one going into a commercial vehicle application.

Fitment guidance

• Listed fitment data includes Honda Civic applications across 1991 to 1995 and Honda CRX applications across 1987 to 1991.
• Listed fitment data also includes Toyota Starlet applications across 1996 to 1999.
• Fitment is supported only by the supplied application data and should still be checked against the part number RXA402 and the physical dimensions of the existing alternator.
• The key matching points are the Denso style unit make, single leg mount, 60A output, 12V system, 64mm 3 groove pulley, 164mm mount centre-to-centre, 58mm mount leg thickness, and the stated hole sizes.

Application and Buying Notes

Before ordering, compare the part number RXA402 with the alternator already fitted to the vehicle. Part number matching is the safest starting point, especially where the application list includes more than one model range and several year variations such as Honda Civic, Honda CRX and Toyota Starlet.

The 12V and 60A rating matter because alternators are selected to suit the vehicle’s charging system and electrical load. The internal regulator also needs to match the vehicle’s expected arrangement, so it is worth confirming the original alternator uses the same regulator type before fitting.

Mounting details are just as important as the electrical rating. This unit uses a single leg mount, 164mm centre-to-centre mounting, a 10mm pivot hole, an M8 x 1.25 adjusting hole, and a 3 groove pulley with 64mm outside diameter. If any of those points differ from the old unit, it may not physically align correctly.

Because this is a remanufactured alternator, it should be checked carefully against the vehicle’s original part and installation space. The stated 4.6kg weight, 58mm mount leg thickness, and Denso style configuration give a practical reference when comparing units side by side on the bench or in the vehicle.

For the best result, confirm the vehicle application, inspect the old alternator for matching pulley and mount details, and check whether the replacement wiring and bracket arrangement correspond to the RXA402 specification. That approach is more reliable than relying on appearance alone, particularly with Denso style alternators that can vary in mounting and pulley arrangement.

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 RXA402 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 60A Denso Style. Part number RXA402 should be checked first. Listed voltage is 12. Listed output rating is 60. 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 3 Groove. Those physical and electrical details should line up with the original unit before the replacement is approved for fitment.

For part number RXA402, 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.

Compatibility note: Confirm compatibility using part number RXA402, the Denso style application, and the stated mounting and pulley dimensions before purchase or installation. Do not rely on vehicle name alone, as fitment should always be checked against the existing alternator and bracket setup.
