OEX Alternator 24V 50A Sawafuji Style SXA728

The OEX Alternator SXA728 is a 24V, 50A rotating electrical component built in a Sawafuji style configuration. It is supplied new, uses an internal regulator, and is listed with a twin leg alternator mount for applications that match the stated mounting dimensions and connector arrangement.

Key physical dimensions include 86mm inside mounting legs, 222mm mount centre to centre, a 14mm pivot hole diameter, a 10mm adjusting hole diameter, an 82mm pulley outside diameter, and a 22mm shaft dimension. The pulley section is listed as BB, and the unit weighs 8.6kg.

This alternator is identified with part number SXA728 and pin code IR188. The wiring note provided is GREEN = Neutral, WHT/BLU = Ignition, and WHT/RED = Warning Lamp. As always with alternators, the safest purchase is the one confirmed against the part number, mount style, voltage, and wiring detail before fitment is attempted.

Application and Buying Notes

Before ordering, compare the alternator against the existing unit or service documentation using the part number SXA728, the 24V system voltage, and the 50A output rating. The mount layout matters as much as the electrical rating, so check the twin leg mount, 86mm inside mounting legs, and 222mm mount centre to centre against the vehicle or equipment already fitted.

The pulley and shaft details are also worth confirming. This unit is listed with an 82mm pulley outside diameter, BB pulley section, and 22mm shaft dimension, so the drive setup needs to match the existing arrangement. A mismatch here can stop the alternator from fitting correctly even if the electrical specification is close.

Wiring should be checked carefully as the note supplied is GREEN = Neutral, WHT/BLU = Ignition, and WHT/RED = Warning Lamp. If the plug, terminal layout, or wire functions on the machine do not match these details, the alternator should be verified further before purchase.

The listed fitment references point to specific FRANNA, HINO, and Toyota Industrial applications, including FRANNA AT-15, FRANNA AT-20, HINO FC, HINO FD, HINO RANGER, TOYOTA INDUSTRIAL 5FD/5FG 50-80, and TOYOTA INDUSTRIAL FORKLIFT. Even where a model family is listed, matching the exact build and installed alternator remains important because equipment variants can differ within the same range.

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 SXA728 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 24V 50A Sawafuji Style. Part number SXA728 should be checked first. Listed voltage is 24. Listed output rating is 50. 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 BB. Those physical and electrical details should line up with the original unit before the replacement is approved for fitment.

For part number SXA728, 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 24 and output 50 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Compatibility note: Confirm fitment by checking part number SXA728, the Sawafuji style application, the 24V 50A rating, the twin leg mount dimensions, and the stated wiring note before ordering.
