OEX Alternator 12V 130A Hitachi Style HXA097

The OEX Alternator HXA097 is a new 12V, 130A unit designed in a Hitachi style configuration. It suits Hitachi applications and uses an internal regulator, a 7 groove pulley, and a twin leg alternator mount. For a replacement alternator, those details matter as much as the amp rating, because pulley, mounting and regulator style all need to match the vehicle setup.

Key measurements on this unit include an 80mm inside mounting leg spacing, a 156mm mount centre-to-centre dimension, a 60mm pulley outside diameter, an M10x1.25 / 10.5 pivot hole diameter, and an M8x1.25 adjusting hole diameter. The unit weighs 6.66kg and is supplied as each.

OEX states its products are sourced from market leading original equipment manufacturers and aftermarket suppliers, with ISO9001 certified factory sourcing and a comprehensive nationwide warranty. For buyers comparing alternators, that gives a clear starting point, but the safest match is still to check the part number HXA097, the Hitachi style layout, and the listed dimensions against the vehicle or removed unit.

Application and Buying Notes

This alternator is specified as a 12V, 130A OEX unit with a Hitachi style layout, so the most important checks are voltage, amp output, mounting style, pulley groove count and regulator type. The twin leg mount and 7 groove pulley are not small details; they need to align with the vehicle’s belt system and bracket arrangement for the alternator to sit and run correctly.

The physical dimensions are also worth checking against the original unit. The 80mm inside mounting legs, 156mm centre-to-centre mount measurement, M10x1.25 / 10.5 pivot hole, and M8x1.25 adjusting hole give you useful reference points when comparing against the removed alternator or vehicle bracketry. If the old alternator has been changed previously, measuring it before purchase is a sensible step.

Although the fitment list includes Infiniti QX80, Nissan Navara, Nissan Pathfinder and Nissan Patrol references, the exact vehicle match still depends on the alternator fitted to the vehicle. Alternators can vary within the same model range, so the safest approach is to confirm the part number HXA097, the Hitachi make reference, and the mount and pulley details before fitting.

The unit is new, not remanufactured, and weighs 6.66kg. That weight and construction detail can help when comparing against a removed unit, especially if you are sorting through multiple alternator options. The warranty is 3 years for passenger use and 1 year for commercial use, so it is still important to follow correct installation practice and make sure the charging system is in good order before and after fitting.

For commercial or high-use vehicles, the 130A output may be relevant where electrical load is higher, but it should still be matched to the vehicle’s intended application. If the belt setup, plug arrangement or mounting offsets are different, do not rely on the amp rating alone. Use the listed dimensions and the part number HXA097 as the primary confirmation points.

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 HXA097 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.
