OEX Alternator 12V 190A Hitachi Style W/cooled HXA112

The OEX Alternator HXA112 is a new 12V, 190A alternator built in a Hitachi style with a cooled design. It is listed as a quad leg alternator mount with a 6 groove pulley, and the unit suits Hitachi applications where those mounting and drive details match.

This alternator is supplied as a new unit, not remanufactured, and carries an internal regulator. The key identifiers are the OEX brand, part number HXA112, 12 volt system voltage, 190 amp output, and a pulley outside diameter of 57mm.

For buyers comparing units, the important checks are the mounting layout, pulley section, and physical dimensions. The listed pivot hole diameter is M8x1.25 / 9, the inside mounting legs measure 61mm, and the mount centre to centre is 127mm.

The unit weighs 7.64kg and is covered by a 3 year passenger / 1 year commercial warranty. OEX describes this range as quality and reliability focused, with ISO9001 certified factories supporting the engineering and testing process.

Application and Buying Notes

Before ordering, compare the part number HXA112 with the alternator already fitted to the vehicle. The confirmed specification here is a 12V, 190A OEX alternator with an internal regulator, Hitachi style casing, 6 groove pulley, and quad leg mounting arrangement.

Physical fit is just as important as electrical output. Check the pivot hole diameter of M8x1.25 / 9, the inside mounting legs at 61mm, the mount centre to centre at 127mm, and the pulley outside diameter of 57mm against the original unit.

The alternator is listed as suited to Hitachi applications, so it is important to match the unit make and mounting layout rather than relying on output alone. A 190A alternator may look similar to lower or higher output units, but the pulley section and bracket arrangement need to line up exactly.

This is a new alternator, so it suits buyers wanting a replacement unit rather than a repairable core. The weight is 7.64kg, which can also help confirm you are comparing like with like when checking an existing alternator against this listing.

Warranty coverage is stated as 3 years for passenger use and 1 year for commercial use. That warranty applies to the supplied OEX unit, but correct fitment still depends on matching the vehicle application, mounting style, and part number before installation.

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 HXA112 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.

Compatibility note: Always confirm compatibility using the part number HXA112, the Hitachi style application, and the listed mounting and pulley measurements before purchase. If the existing alternator differs in regulator type, mount layout, or pulley configuration, it should be checked carefully before ordering.
