OEX Alternator 24V 50A Sawafuji Style SXA709

The OEX SXA709 is a new 24V alternator rated at 50 amps and listed as Sawafuji style. It is a twin leg mount unit with an internal regulator, a BB pulley section, and a pulley outside diameter of 82mm, so those physical checks matter alongside the part number when confirming a match.

Key dimensions include 87mm inside mounting legs, a 220mm mount centre to centre measurement, a 14mm pivot hole diameter, a 10mm adjusting hole diameter, and a 17mm shaft dimension. The unit weighs 9.2kg and is supplied as a new alternator, not remanufactured.

The listed pin code is IR34, with the note: 28.7V - BK/W, 14V - Y/W, R ignition - W, L warning lamp - R/W. That wiring detail is important when comparing the alternator to the existing unit and the vehicle’s charging circuit before purchase.

Application and Buying Notes

When comparing this alternator to your existing unit, start with the part number SXA709 and the fitment style listed as Sawafuji. The physical mounting details are just as important: 87mm inside mounting legs, 220mm centre to centre, a 14mm pivot hole, and a 10mm adjusting hole all need to align with the original arrangement.

The alternator is a 24V, 50A unit with an internal regulator, so it should only be considered where those electrical details match the vehicle’s charging system. The pin code IR34 and the note covering 28.7V - BK/W, 14V - Y/W, R ignition - W, and L warning lamp - R/W are useful reference points when checking the connector and wiring before fitting.

Pulley details can also decide whether a replacement is suitable. This unit uses an 82mm outside diameter pulley with a BB pulley section and a 17mm shaft dimension, so pulley alignment and belt compatibility should be checked carefully against the original alternator.

For commercial and industrial applications, it is worth matching more than just the broad vehicle family. The listed application data spans Hitachi, Isuzu, Mitsubishi Fuso, Nissan Industrial, Nissan UD, UD Nissan Diesel, and UD Trucks, but the exact engine or machine application still needs to be confirmed against the part number and the physical unit on the vehicle.

The warranty listed is 3yr Passenger 1yr Commercial. That is a useful buying reference, but it does not replace fitment confirmation. Alternators in this category are sensitive to mounting style, regulator type, wiring pin code, and pulley dimensions, so those checks should be completed before ordering.

If you are replacing a charging component on a truck, excavator, or industrial vehicle, keep the old alternator on hand when comparing. The 9.2kg weight, twin leg mount, and Sawafuji style listing can help narrow it down, but the safest approach is still to confirm the full application details against the existing unit and vehicle requirements.

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 SXA709 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.
