Mitsubishi Alternator 24V 90A A4TA8492AMA

The Mitsubishi Alternator 24V 90A is a new rotating electrical unit with part number A4TA8492AMA. It is rated at 24 volts and 90 amps, with an internal regulator and a single leg alternator mount, so the key matching points are the electrical rating, mount style and the listed pulley and shaft dimensions.

This unit is supplied as each and carries a 2 Years 400,000km warranty. The alternator weighs 7.5kg and uses a 12 groove pulley with a 69mm outside diameter, so it is important to compare the pulley style and mounting measurements against the original unit before ordering.

The listed notes state that an original pulley may be required if needed, and that an adaptor is suitable for HXK-30, HXK-22 and HXK-17. That makes the part number, pulley section and mounting layout especially important when checking replacement suitability on the vehicle.

Mitsubishi is shown as both the brand and the unit make, and the product is described as a Mitsubishi Alternator 24V 90A. If you are replacing a worn alternator, confirming the original alternator details and the application listing is the safest way to avoid installation issues.

Application and Buying Notes

Before ordering, check the part number A4TA8492AMA against the old alternator and compare the 24V 90A rating with the existing unit. The mounting details also matter: this alternator uses a single leg mount, a 58mm mount leg thickness, an 11mm pivot hole and an M8 adjusting hole, so the physical layout needs to line up with the vehicle and bracket.

The pulley arrangement is another key check point. This alternator has a 12 groove pulley with a 69mm outside diameter, and the note advises that the original pulley may be required if needed. If the existing drive setup uses a different configuration, the pulley and adaptor details should be checked carefully before fitting.

For vehicles in the listed application groups, confirm the specific model and year shown in the fitment information, then match that to the original unit on the vehicle. Even where the model family is listed, alternators can differ by bracket style, pulley setup or connector details, so matching by part number and measurements is still the best approach.

The internal regulator and 24V output suit heavy vehicle electrical systems where the charging specification must remain consistent. If the old alternator shows signs of wear, it is still worth confirming the shaft dimension of 17, the 171mm mount centre to centre measurement and the adaptor note before purchase, as these details can affect installation and alignment.

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 A4TA8492AMA 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.

For part number A4TA8492AMA, 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 ASTRA ADT25C, ASTRA ADT25C 2008, ASTRA ADT25C 2009, ASTRA ADT30C, CASE 335B, CASE 335B 2008. 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 compatibility by matching part number A4TA8492AMA, the 24V 90A rating, the single leg mount, and the 12 groove pulley details against the original alternator and vehicle application before ordering.
