OEX Alternator 12V 60A Hitachi Style HXA038

The OEX Alternator HXA038 is a new 12V, 60A unit built in Hitachi style for applications that use a Hitachi alternator pattern. It is a twin leg mount alternator with a 175mm centre-to-centre mounting measurement, 80mm inside mounting legs, and an 8mm pivot hole diameter.

This alternator is supplied with an internal regulator and a pulley outside diameter of 72mm with an A section pulley. The unit weighs 5.5kg and includes a P terminal for stator phase output or tacho signal, with an adaptor to suit HXK-18 noted for installation checking.

OEX lists this alternator under part number HXA038, and the unit is described as a new replacement for rotating electrical applications. As with any alternator change, the key checks are the mounting arrangement, pulley dimensions, connector style, and whether the vehicle or machine uses a Hitachi-style unit.

OEX states its products are sourced from Original Equipment Manufacturers and aftermarket suppliers, with ISO9001-certified factory support and a nationwide warranty program. Warranty on this alternator is listed as 3 years for passenger use and 1 year for commercial use.

Application and Buying Notes

Before ordering, check that your existing alternator is a Hitachi style unit and that the mounting layout matches the twin leg design, 175mm centre-to-centre measurement, and 80mm inside mounting legs listed here. The pivot hole diameter is 8mm and the adjusting hole is M8x1.25, so those measurements need to line up with the bracket and adjuster arrangement on the vehicle or machine.

Pulley fitment matters just as much as electrical output. This alternator uses a 72mm outside diameter pulley with an A section belt profile, so the belt section and pulley size should be confirmed against the unit being replaced. If the belt line, pulley offset, or shaft dimension of 17 differs from the original unit, it may not be a direct swap.

The alternator is rated at 12V and 60A, which is suitable where the original charging system specification calls for that output. The internal regulator and P terminal also need to match the vehicle’s wiring and any tacho or phase output requirements, especially where the original alternator connector layout is specific.

The listed application groups cover a wide range of equipment and vehicles, including Hitachi, Ford Maverick, Holden Astra, Isuzu 4JB1, JCB JS70, John Deere 17ZTS, Nissan Navara, and others. That range is helpful for cross-referencing, but the safest approach is still to confirm the part number HXA038 and compare the physical measurements before purchase.

If you are replacing an alternator on commercial equipment, pay attention to the listed warranty difference between passenger and commercial use. The product is new and carries OEX warranty coverage, but the correct application match remains the buyer’s responsibility before installation.

The note about an adaptor to suit HXK-18 is important for anyone matching connectors or mounting accessories. That adaptor reference does not replace the need to compare your original alternator, but it does give a useful checkpoint when assessing the installation hardware and plug arrangement.

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 HXA038 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 12V 60A Hitachi Style. Part number HXA038 should be checked first. Listed voltage is 12. Listed output rating is 60. 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 A. Those physical and electrical details should line up with the original unit before the replacement is approved for fitment.

For part number HXA038, 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.

Compatibility note: Confirm fitment by comparing part number HXA038, Hitachi-style application details, twin leg mount measurements, pulley size, regulator type, and the P terminal/adaptor note before ordering.
