OEX Alternator 12V 90A Mitsubishi Style HXA111

The OEX Alternator HXA111 is a 12V, 90A unit with an internal regulator and Mitsubishi suitability. It is listed with a clockwise rotation, AA pulley section, and a 82mm pulley outside diameter, which makes the physical details just as important as the electrical rating when checking replacement suitability.

Mounting dimensions matter on alternators, and this unit is specified with twin leg mounting, 81mm inside mounting legs, 176mm mount centre to centre, a 10mm pivot hole diameter, and a 9mm adjusting hole diameter. Those measurements are the practical checkpoints for confirming whether the alternator will line up correctly in the vehicle.

This alternator is identified as OEX part number HXA111 and is supplied as an each item. It carries a 3 year passenger / 1 year commercial warranty, and the insulated return is listed as No, so it is best matched by verifying the part number, mounting layout, and electrical specification before ordering.

Application and Buying Notes

Before buying, match the existing alternator against the key identifiers on this unit: HXA111, 12V, 90A, internal regulator, and Mitsubishi style. A close visual match is not enough on its own if the mounting points or pulley details differ, so check the 81mm inside mounting legs, 176mm mount centre to centre, and the 82mm pulley outside diameter against the original part.

The rotation is clockwise, and the pulley is listed as AA section. Those details are important where belt alignment and drive configuration need to match the vehicle’s original setup. If the belt profile, pulley section, or drive direction is different from what is fitted now, the alternator may not be suitable even if the plug and casing look similar.

This unit is identified as having a twin leg mount with a 10mm pivot hole and 9mm adjusting hole, so the bracket style needs to line up correctly with the vehicle’s alternator arrangement. The listed weight is 6kg, which can also be a useful comparison point when replacing a removed unit and checking that the replacement is in the expected size range.

Fitment information supplied for this product points to Nissan and Nissan Navara applications, including references to Navara model years from 2002 through 2012. That makes application checking important rather than assuming fitment from the brand or output alone. Use the part number HXA111 and the listed dimensions to confirm the replacement matches the vehicle you are working on.

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 HXA111 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 a alternator in workshop, fleet, trade, agricultural, or construction service, the listed voltage 12 and output 90 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Available application references include NISSAN NAVARA, NISSAN NAVARA 2002, NISSAN NAVARA 2003, NISSAN NAVARA 2004. Even with application listings, final confirmation should still be based on the exact unit being replaced and the service requirements of the vehicle or machine.
