OEX Alternator 24V 50A Hitachi Style HXA041

The OEX Alternator HXA041 is a 24V, 50A unit with an internal regulator and a twin leg alternator mount. It is listed as new and is identified as a Hitachi style alternator, so the key checks are the mounting dimensions, pulley section, shaft dimension, and the application details before ordering.

For fitment, the confirmed application data supplied with this part includes ISUZU, MAZDA and UD Nissan Diesel ranges, including ELF, E-Series, T-Series, Titan, Condor and LK Series entries across multiple model years. Because alternators are built around mount style and physical dimensions as much as voltage and amperage, matching the part number HXA041 and the listed measurements is the safest way to confirm suitability.

This alternator is a rotating electrical component sold each, with a weight of 9.08kg. It is described as suitable for a 50cc vacuum pump and includes an adaptor to suit HXK-08, which is important to note if the vehicle uses that accessory arrangement. The product is backed by OEX’s listed warranty terms of 3 years for passenger use and 1 year for commercial use.

Application and Buying Notes

Before buying, compare the alternator mount and dimensions on your vehicle with the listed measurements: inside mounting legs 81mm, mount centre to centre 175mm, pivot hole diameter 10mm, adjusting hole diameter 8mm, and shaft dimension 17. These checks matter because alternators that share a similar appearance can still differ in mounting spacing, pulley setup, or shaft size.

The listed electrical specification is 24V and 50A, so this part suits systems built to that rating. It also has an internal regulator, which should be matched to the vehicle’s charging system design. If your vehicle uses a separate regulator arrangement, the electrical layout needs to be checked carefully before purchase.

The note supplied with this alternator mentions a 50cc vacuum pump and an adaptor to suit HXK-08. That detail can be relevant where the accessory drive or pump arrangement is part of the installation. The pulley section is AAA, so the belt profile should also be checked against the existing unit.

Application data is supplied for ISUZU, MAZDA and UD Nissan Diesel ranges, including ELF, E-Series, T-Series, Titan, Condor and LK Series entries. Even when a vehicle family is shown, confirmation should still be made against the part number HXA041 and the physical specifications, as model-year and build variations can affect alternator fitment.

OEX states that its products are sourced from market leading original equipment manufacturers and aftermarket suppliers, and that its factories are ISO9001 certified for engineering, testing and quality control procedures. The listed warranty is 3 years for passenger use and 1 year for commercial use, so it is worth matching the intended use of the vehicle to those warranty terms when selecting the part.

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 HXA041 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.
