Application and Buying Notes

Before ordering, confirm the alternator mounting arrangement on the vehicle matches the twin leg layout, 84mm inside mounting legs, and 157mm centre to centre dimension. Those measurements are the practical checks that help avoid a mismatch even when the application name looks close.

The pulley is a 6 groove type, so belt alignment and groove count need to match the existing setup. The unit also has an internal regulator and an external sense S terminal, which means the electrical connection arrangement should be checked against the vehicle before installation.

If you are comparing this against an existing alternator, use the part number HXA093 as the main reference and then cross-check the physical dimensions, voltage, amperage, and terminal arrangement. The listed 12V 110A output is suitable only where that charging specification is required.

This is a Hitachi style alternator, so fitment should be confirmed by application details as well as the mechanical dimensions. The same model name alone is not enough if the mount type, pulley section, or wiring setup differs from the existing unit.

For commercial use, the warranty listing is 1 year, while passenger use is 3 years. Keep that in mind if the vehicle has heavier electrical demand or sees mixed duty, and make sure the installation is carried out on the correct application to avoid unnecessary downtime.

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 HXA093 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.
