OEX Alternator 12V 90A Autolite Style AXA978

The OEX AXA978 is a new 12V alternator rated at 90 amps, built in an Autolite style with a pad mount arrangement. It uses an internal regulator, a 6 groove pulley, and a 73mm inside mounting leg measurement, so matching the physical layout is just as important as matching the electrical specification.

This unit is supplied as each and carries a 3 year passenger / 1 year commercial warranty. The listed pin code is IR99, the pulley outside diameter is 59mm, and the mount centre to centre measurement is 175mm, which are the key checks to compare against the removed unit before ordering.

OEX states that its products are sourced from market leading original equipment manufacturers and aftermarket suppliers, with production from ISO9001 certified factories. In practical terms, this alternator is intended for buyers who want a replacement unit identified by part number AXA978 and need to confirm the 12V, 90A specification against the existing application.

Application and Buying Notes

Before ordering, compare the removed alternator with the important identifiers on this unit: AXA978, Autolite style, 12V, 90A, internal regulator, and pad mount. The fitment data provided also points to applications across Alfa Romeo 147, Citroen BX, Ford Focus, Jaguar X-Type and Jaguar XF, but the exact version still needs to match the vehicle and the existing unit.

The physical measurements matter here because alternators that look similar can differ in mounting and pulley details. Check the 73mm inside mounting legs, 175mm mount centre to centre, 10mm adjusting hole diameter, 10 / 13mm pivot hole diameter, 55mm mount leg thickness, and 59mm pulley outside diameter before you buy.

The 6 groove pulley and IR99 pin code are useful checkpoints when comparing the replacement against the original unit. If the car has been changed previously, or if the existing alternator is not original to the vehicle, the part number and measurements are the safest way to confirm the correct replacement.

This alternator is supplied new and is backed by the stated warranty period of 3 years for passenger use and 1 year for commercial use. For a proper match, verify both the electrical specification and the mounting layout, because a 12V 90A alternator can still differ from other Autolite style units in pulley, regulator, or bracket dimensions.

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 AXA978 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.
