OEX Alternator 24V 90A Sawafuji Style SXA721

The OEX SXA721 is a new 24V 90A alternator in Sawafuji style, supplied as an alternator each. It is listed with an internal regulator, 8 groove pulley, twin leg mounting, and a 76mm pulley outside diameter.

This unit is identified with Part No. SXA721 and Pin Code IR208. Key mounting dimensions are 85mm inside mounting legs, 235mm mount centre to centre, 14mm pivot hole diameter, and 10mm adjusting hole diameter. Those measurements matter when matching the alternator to the vehicle or machine already fitted.

OEX lists this alternator as OE product, sourced from an ISO standards approved company. It weighs 8kg and is covered by a 3yr passenger / 1yr commercial warranty, which is useful to know when comparing it with other 24V replacement units of the same style.

Application and Buying Notes

Before ordering, compare the part number SXA721, the Sawafuji style application, and the physical mounting measurements against the alternator being replaced. The listed 24V charging system, 90A output, twin leg mount, 85mm inside mounting legs, and 235mm mount centre to centre need to line up with the vehicle or machine installation.

The pulley details are also important. This unit has an 8 groove pulley with a 76mm outside diameter, so the belt type and pulley size should be checked carefully before purchase. If the existing alternator has a different groove count, pulley diameter, or shaft arrangement, it may not be a direct match.

Because fitment is tied to specific applications, the safest check is to confirm both the model family and the physical dimensions. The listed references include Hino 500 Series, Hino FC, Hino FD, Hino Ranger, Hino RG, Kobelco SK series applications, and UD Nissan Diesel and UD Trucks Condor and MK Series applications, but the exact installation still needs to match the unit already fitted.

The internal regulator is another detail worth confirming when replacing a charging component. Some installations rely on the alternator’s built-in regulation arrangement, so it is sensible to verify the existing system before fitting. If the previous alternator has different electrical connections, different pulley layout, or different mounting points, the correct replacement should be checked by part number and dimensions rather than appearance alone.

For commercial use, the warranty listed is 1 year, while passenger use is listed at 3 years. That warranty detail does not replace fitment checking, but it does provide a clear comparison point when reviewing replacement options for a 24V, 90A alternator in this style.

The unit is new, not remanufactured, and weighs 8kg. Those details can help when comparing against removed parts or exchange units, especially where condition, handling, and installation planning matter on larger vehicles or equipment.

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 SXA721 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.

Additional published details for cross-checking include Product Group 2 ALTERNATORS, Part No. SXA721, Brand OEX, Description OEX Alternator 24V 90A Sawafuji Style, Adjusting Hole Diameter 10, Pin Code IR208, Power Rating (Amp) 90, Pulley Section 8 Groove, Suits Unit Make Sawafuji.

OEX Alternator 24V 90A Sawafuji Style. Part number SXA721 should be checked first. Listed voltage is 24. Listed output rating is 90. 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 8 Groove. Those physical and electrical details should line up with the original unit before the replacement is approved for fitment.

For part number SXA721, 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 90 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Available application references include HINO 500 SERIES, HINO 500 SERIES 1995, HINO 500 SERIES 1996, HINO 500 SERIES 1997, KOBELCO SK300LC-10, KOBELCO SK300LC-10 2017. 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: Confirm fitment by matching Part No. SXA721, the Sawafuji style application, and the alternator dimensions and mounting details against the unit currently fitted to the vehicle or machine.
