Application and Buying Notes

Before buying, compare the original alternator against the key identifiers on this unit: OEX SXA729, Sawafuji style, 24V, 90A, internal regulator, and twin leg mount. The mounting dimensions are specific, including 86mm inside mounting legs and 235mm mount centre to centre, so a close physical match matters.

The pulley detail is also important. This alternator has a 10 groove pulley with a 70mm outside diameter, so the belt configuration on the vehicle needs to match the replacement unit. The supplied pivot hole diameter is 14mm and the adjusting hole diameter is 10.5mm, which are useful checkpoints when comparing brackets.

If you are replacing a failed alternator, check the electrical system voltage before ordering. This unit is 24V and rated at 90A, so it is not a universal substitute for 12V or different-output applications. The listed 15kg weight can also help with identification when comparing the old part on the vehicle or over the counter.

Warranty is listed as 3 years for passenger use and 1 year for commercial use, so it is worth confirming how the vehicle will be used. The unit is new rather than remanufactured, and the listed OE product note indicates it is sourced from an ISO standards approved company.

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 SXA729 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 90A Sawafuji Style. Part number SXA729 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 10 Groove. Those physical and electrical details should line up with the original unit before the replacement is approved for fitment.

For part number SXA729, 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.

Compatibility note: Confirm fitment using the SXA729 part number, Sawafuji style application, 24V system requirement, 90A output, and the supplied mounting and pulley measurements before purchase.
