Application and Buying Notes

Before ordering, compare the vehicle’s existing alternator against the key identifiers on this unit: OEX part number HXA049, 12V system voltage, 60A output, twin leg mount, and 73mm pulley diameter. These details are often the quickest way to rule a part in or out before removal and reinstallation work begins.

Mounting dimensions should be checked carefully. This alternator is listed with 80mm inside mounting legs, 176mm mount centre-to-centre, a 10mm pivot hole diameter, and an M8x1.25 adjusting hole. If any of these points differ from the unit already on the vehicle, fitment should be confirmed before purchase.

The pulley and shaft details also need attention. The pulley is an A section type with a 73mm outside diameter, and the shaft dimension is 17mm. The note supplied with the part mentions a 30cc vac pump, so any vehicle or equipment using a vacuum pump arrangement should be checked against the existing assembly rather than assumed to match.

This alternator is described as Hitachi style and suited to Hitachi units, but style alone is not enough for a safe purchase decision. Part number, regulator type, mounting arrangement, pulley size, and vacuum pump requirement should all be matched to the removed component or the vehicle’s parts listing.

The warranty is 3 years for passenger use and 1 year for commercial use. Warranty terms do not replace fitment confirmation, so it is still important to verify the electrical and mechanical specifications before fitting the part.

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 HXA049 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 HXA049, 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 12 and output 60 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Compatibility note: Confirm fitment by matching the OEX part number HXA049, the 12V 60A specification, twin leg mounting details, pulley dimensions, and the 30cc vac pump note against the existing alternator and vehicle application before ordering.
