OEX Alternator 24V 80A Hitachi Style HXA064

The OEX Alternator HXA064 is a new 24V, 80A unit built in Hitachi style for applications that require a Twin Leg alternator mount and an internal regulator. Key dimensions include 78mm inside mounting legs, 175mm mount centre to centre, an M8 pivot hole, an 8mm adjusting hole, a 17mm shaft dimension, and a 69mm pulley outside diameter.

This alternator is listed as suit unit make Hitachi and uses a 7 groove / A pulley section. It is supplied as each unit, weighs 8kg, and is identified by part number HXA064 and pin code IR49. These details matter when matching brackets, pulley alignment, electrical setup, and physical clearance in the vehicle.

OEX states its products are sourced from market leading original equipment manufacturers and aftermarket suppliers, with factories that are ISO9001 certified to support engineering, testing, and quality control procedures. The alternator is backed by a 3 year passenger and 1 year commercial warranty, which gives you a clear service expectation based on the application class.

Application and Buying Notes

Before ordering, compare the part number HXA064, pin code IR49, and the Hitachi style description against the alternator already fitted to the vehicle. The 24V system voltage and 80A output need to match the electrical system requirements of the application, particularly on commercial and machinery use where regulator type and charging profile matter.

Physical fit is just as important as electrical fit. Check the Twin Leg mount, 78mm inside mounting legs, 175mm mount centre to centre, M8 pivot hole, 8mm adjusting hole, 17mm shaft dimension, and 69mm pulley outside diameter against the original unit. If any of those measurements differ, the alternator may not align correctly or may not install without modification.

The pulley is a 7 groove / A type, so belt profile and alignment should be confirmed before purchase. Because the part is listed for Hitachi unit make and carries multiple application references across CASE, ISUZU and MAZDA, the safest approach is to verify the existing alternator by label, dimensions, and pulley detail rather than relying on the vehicle make alone.

This is a new alternator supplied by OEX and weighs 8kg, so it is appropriate to compare the replacement against the old unit before fitting. The warranty is 3 years for passenger use and 1 year for commercial use, which is useful context when selecting the part for the intended duty cycle, but it does not replace the need to confirm the exact application.

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 HXA064 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. HXA064, Brand OEX, Description OEX Alternator 24V 80A Hitachi Style, Adjusting Hole Diameter 8, Pin Code IR49, Power Rating (Amp) 80, Pulley Section 7 Groove / A, Suits Unit Make Hitachi.

OEX Alternator 24V 80A Hitachi Style. Part number HXA064 should be checked first. Listed voltage is 24. Listed output rating is 80. 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 7 Groove / A. Those physical and electrical details should line up with the original unit before the replacement is approved for fitment.

For part number HXA064, 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 80 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Compatibility note: Confirm compatibility by matching the HXA064 part number, IR49 pin code, 24V / 80A rating, Hitachi style, mount type, and the listed dimensions against the vehicle’s original alternator before purchase.
