OEX Alternator 12V 110A Hitachi Style HXA108

The OEX Alternator HXA108 is a new 12V unit rated at 110A and built in a Hitachi style configuration. It is listed as a twin leg alternator with an internal regulator, a 6 groove pulley, and a pulley outside diameter of 62mm, so the key mounting and drive details are already defined for checking against the vehicle application.

This alternator is supplied under the OEX brand and is described as suited to Hitachi units. Mounting dimensions include 82mm inside mounting legs, a 170mm mount centre-to-centre measurement, a 10.5mm pivot hole diameter, and an M8x1.25 adjusting hole diameter. Those figures are the main points to verify before ordering, especially where the original unit has to match closely.

The unit weighs 5.94kg and carries a 3 year passenger / 1 year commercial warranty. OEX states its products are sourced from market leading original equipment manufacturers and aftermarket suppliers, with ISO9001 certified factory sourcing to support engineering, testing, and quality control procedures.

Application and Buying Notes

For a correct match, compare the alternator’s 12V system, 110A output, and Hitachi style layout with the vehicle’s original unit. The listed twin leg mount, 82mm inside mounting legs, 170mm centre-to-centre mounting distance, 10.5mm pivot hole, and M8x1.25 adjusting hole are the most useful checks when replacing an existing alternator.

The 6 groove pulley and 62mm pulley outside diameter should also be checked carefully, as belt drive detail can differ even when the alternator looks similar. If the original alternator has a different pulley section or mounting arrangement, the part may not be suitable without further verification.

This is a new alternator, and the internal regulator means regulation is built into the unit itself. That matters when comparing it to an existing setup, because external-regulator and internal-regulator systems are not interchangeable without confirming the vehicle’s charging arrangement.

The supplied fitment references Nissan Patrol applications, but the safest approach is still to verify by part number and the physical mounting dimensions. Matching HXA108, the Hitachi style description, and the listed measurements gives a much stronger check than relying on appearance alone.

For commercial use, the warranty is listed as 1 year, while passenger use is listed as 3 years. If the vehicle is used in mixed conditions or for work, it is worth confirming the intended warranty basis before fitting so there is no confusion later.

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 HXA108 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.

OEX Alternator 12V 110A Hitachi Style. Part number HXA108 should be checked first. Listed voltage is 12. Listed output rating is 110. 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 HXA108, 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 110 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Available application references include NISSAN PATROL, NISSAN PATROL 1997, NISSAN PATROL 1998, NISSAN PATROL 1999. 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 compatibility by checking the OEX part number HXA108, the Hitachi style alternator description, the twin leg mount, and the listed pulley and mounting dimensions against the original unit before ordering.
