OEX Alternator 12V 80A Mitsubishi Style RXA356

The OEX RXA356 is a 12V, 80A alternator in Mitsubishi style with an internal regulator and a twin leg mount. It is listed as remanufactured and carries a 3yr passenger / 1yr commercial warranty, which gives a clear buying reference for owners and workshops comparing alternator replacements by specification rather than appearance alone.

Key mounting and drive details matter on alternators, and this unit includes a 60mm pulley with a 4 groove section, 55mm inside mounting legs, a 10mm pivot hole, a 9mm adjusting hole, and 180mm mount centre to centre. Those measurements are the details that should be checked against the vehicle’s original unit before ordering.

This alternator is described as OEX Alternator 12V 80A Mitsubishi Style, with part no. RXA356 and pin code IR70. It weighs 4.84kg and is sold each. For electrical replacement work, matching the part number, voltage, amp rating, and mounting layout is the most reliable way to narrow the correct option.

Application and Buying Notes

Before ordering, compare the RXA356 part number, 12V system voltage, 80A output, and the twin leg mounting pattern with the alternator already fitted to the vehicle. The 55mm inside mounting legs, 180mm mount centre to centre, 10mm pivot hole, and 9mm adjusting hole are the practical dimensions that can make the difference between a direct fit and an alternator that looks close but does not line up correctly.

The pulley details also need checking. This alternator uses a 60mm outside diameter pulley with a 4 groove section, so belt type and pulley alignment should be confirmed against the original unit. If the belt arrangement or pulley profile does not match, the alternator may not suit the application even where the electrical rating appears suitable.

This unit is listed for Mitsubishi style applications and the supplied fitment references include Mitsubishi, Mitsubishi FTO, Mitsubishi Galant, Mitsubishi Legnum, Mitsubishi Sigma, Chrysler Sigma, Datsun 620, International Harvester CM-Series, and Subaru Leone. Those references are useful as a guide, but alternator fitment can still vary by build date, engine, and existing bracket setup, so the vehicle-specific details should always be verified.

Because this is a remanufactured alternator, it is sensible to inspect the mounting faces, wiring plug arrangement, belt path, and clearance around the rear of the unit before installation. The weight is listed at 4.84kg, which can also help when comparing against the removed alternator if the original unit is available for direct comparison.

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 RXA356 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 80A Mitsubishi Style. Part number RXA356 should be checked first. Listed voltage is 12. Listed output rating is 80. 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 4 Groove. Those physical and electrical details should line up with the original unit before the replacement is approved for fitment.

For part number RXA356, 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 80 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Available application references include CHRYSLER SIGMA, CHRYSLER SIGMA 1977, CHRYSLER SIGMA 1978, CHRYSLER SIGMA 1979, DATSUN 620, DATSUN 620 1970. 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 matching the RXA356 part number, 12V 80A rating, twin leg mount, pulley section, and mounting dimensions to the original alternator and vehicle application before purchase.
