OEX Alternator 12V 90A Hitachi Style HXA080

The OEX Alternator HXA080 is a new 12V unit rated at 90A and built in a Hitachi style configuration. It is listed with a twin leg alternator mount, 6 groove pulley section, internal regulator, and a 17mm shaft dimension, so the physical dimensions matter as much as the electrical rating when checking replacement suitability.

Key mounting dimensions for this alternator include 82mm inside mounting legs, 157mm mount centre to centre, 10mm pivot hole diameter, and 10mm adjusting hole diameter. The pulley outside diameter is 63mm, which is important to confirm against the original unit before ordering.

This alternator is identified as part number HXA080 and is marked for Hitachi application. It is a new unit, weighs 4.94kg, and is sold as each. Where the vehicle application is not being confirmed by VIN or direct part match, the safest approach is to compare the part number and all listed dimensions before purchase.

Application and Buying Notes

Before ordering, compare the part number HXA080 with the original alternator and check the mounting pattern carefully. The listed dimensions of 82mm inside mounting legs, 157mm mount centre to centre, 10mm pivot hole diameter and 10mm adjusting hole diameter are the key physical checks for a correct swap.

The electrical side also needs to match. This unit is 12V and rated at 90A with an internal regulator, so it should only be considered where the original alternator shares those same basic requirements. The 6 groove pulley section and 63mm pulley outside diameter must also line up with the drive arrangement on the vehicle.

Because alternators can look similar while still differing in mount spacing, shaft size or pulley setup, rely on the listed measurements rather than appearance alone. The shaft dimension is 17mm and the unit is described as Hitachi style, which makes direct comparison with the removed part the most reliable way to confirm suitability.

If you are fitting to a Nissan or UD Nissan Diesel application, use the application list as a guide only and confirm against the vehicle’s original alternator details. Matching the make family is not enough on its own; the part number, mount style, pulley section and hole diameters should all be checked 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 HXA080 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.

Additional published details for cross-checking include Product Group 2 ALTERNATORS, Part No. HXA080, Brand OEX, Description OEX Alternator 12V 90A Hitachi Style, Adjusting Hole Diameter 10, Pin Code IR49, Power Rating (Amp) 90, Pulley Section 6 Groove, Suits Unit Make Hitachi.

OEX Alternator 12V 90A Hitachi Style. Part number HXA080 should be checked first. Listed voltage is 12. Listed output rating is 90. These details form the core reference points used by parts interpreters when confirming the correct replacement.

Mount style is Twin Leg. Regulator type is Internal. Pulley configuration is 6 Groove. Those physical and electrical details should line up with the original unit before the replacement is approved for fitment.

For part number HXA080, the normal identification sequence is part number, electrical rating, mounting arrangement, connector or terminal style, and pulley or drive details. Using those checkpoints helps confirm that the listed unit matches the service requirement rather than only looking similar.

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 200SX, NISSAN 200SX 1994, NISSAN 200SX 1995, NISSAN 200SX 1996, UD NISSAN DIESEL PK SERIES, UD NISSAN DIESEL PK SERIES 1995. 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.

The listed warranty is 3yr Passenger 1yr Commercial. Warranty terms should be considered alongside correct application and part identification, as warranty does not replace fitment confirmation.

Compatibility note: Confirm fitment by matching part number HXA080, the Hitachi style application, and the listed dimensions and electrical specifications against the original alternator and vehicle application details before purchase.
