OEX Alternator 12V 90A Mitsubishi Style MXA329

The OEX Alternator MXA329 is a 12V, 90A unit built in a Mitsubishi style arrangement and supplied as a new alternator for rotating electrical applications. It uses a 6 groove pulley, a pad mount, and a field control unit regulator type, so it is important to match the replacement against the vehicle’s charging system and mounting layout before ordering.

This alternator is listed with ECU Voltage Control and an adaptor to suit HXK-32 and HXK-24. The mounting measurements supplied are a 174mm mount centre to centre, with 10mm adjusting hole diameter and 10mm pivot hole diameter, which are practical checks when comparing the unit to the original alternator already on the vehicle.

Key identification details for this part are OEX, part number MXA329, voltage 12, power rating 90 amp, and pin code IR29. The pulley outside diameter is 59mm and the shaft dimension is 17, with a stated weight of 6.66kg. These are the details to cross-check when confirming a direct replacement or a like-for-like swap.

As with any alternator replacement, the safest approach is to verify the mount style, pulley section, regulator type, and connector arrangement against the original unit. The fitment information supplied points to Mitsubishi-style applications, and the alternator should only be selected once the part number and physical specifications align with the vehicle already fitted.

Application and Buying Notes

Before buying, compare the MXA329 alternator against the unit currently on the vehicle by checking the 12V system, 90A output, 6 groove pulley, pad mount, and the 174mm centre-to-centre mounting dimension. Those points matter because alternators that look similar can differ in pulley section, regulator type, or mounting spacing even when they are from the same broad family.

The note for ECU Voltage Control and the adaptor to suit HXK-32 and HXK-24 is especially important. If the original alternator uses a different connector or control arrangement, the replacement may not be correct without the matching adaptor and the same control strategy. Confirm the pin code IR29 and the field control unit regulator type against the existing setup before fitting.

Physical measurements are often the quickest way to avoid a mismatch. The adjusting hole diameter and pivot hole diameter are both 10mm, the pulley outside diameter is 59mm, and the shaft dimension is 17. These figures should be checked against the old unit, along with the mounting ears and belt line, so the alternator sits correctly and the belt alignment remains correct.

The supplied fitment information references Ford, Mazda, and UD Nissan Diesel applications, including Escape, Kuga, Mazda 3, Mazda 6, CX-7, Tribute, C Series, and Condor. Even so, vehicle fitment still needs to be confirmed by part number and the alternator’s physical specification set, because the same model range can use more than one charging system configuration.

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 MXA329 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 90A Mitsubishi Style. Part number MXA329 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 Pad. Regulator type is Field Control Unit. 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 MXA329, 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.

Compatibility note: Confirm fitment by matching part number MXA329, 12V 90A output, 6 groove pulley, pad mount, IR29 pin code, and the listed mounting measurements against the vehicle’s original alternator before purchase.
