Mitsubishi Alternator 24V 80A A4TUG081AMA

This Mitsubishi alternator is a 24V, 80A unit identified by part number A4TUG081AMA. It is listed as a new alternator, supplied as each, and it is described as an OE product. For buyers matching a replacement charging unit, the key checks here are voltage, amperage, mounting style, pulley layout, and the part number.

The unit uses a twin leg alternator mount, with inside mounting legs measuring 43mm and mount centre to centre at 190mm. The adjusting hole diameter is M12x1.25, which is a useful checkpoint when comparing against the existing alternator and bracket arrangement. The regulator type is internal, so the regulator is part of the alternator assembly.

This alternator is fitted with a 6 groove pulley, 65mm pulley outside diameter, and pin code IR18. Those details matter when matching the belt drive and electrical connection setup on the vehicle. The unit weighs 9.54kg, which can also help confirm you are comparing like for like when removing the old alternator.

Application and Buying Notes

The most reliable way to confirm compatibility is to compare the part number A4TUG081AMA, the 24V system requirement, and the 80A output against the alternator already fitted to the vehicle. If any of those key details differ, the unit may not be the correct replacement even if it looks similar from the outside.

Mounting measurements are just as important as the electrical rating. This alternator has a twin leg mount, 43mm inside mounting legs, 190mm mount centre to centre, and an M12x1.25 adjusting hole diameter. Those dimensions need to line up with the bracket, adjuster, and fixing points already on the vehicle.

The pulley arrangement also needs to match. This unit uses a 6 groove pulley with a 65mm outside diameter, so the belt profile and pulley size should be checked against the existing alternator before ordering. The internal regulator and IR18 pin code should also be compared carefully where the wiring and connector style are part of the original setup.

Because fitment data has not been supplied for specific vehicle models, it is best to treat this as a part-number and specification match rather than a model-based assumption. A direct visual comparison of the old alternator, along with the mounting and electrical details above, will reduce the chance of ordering the wrong unit.

The listed 2 years / 400,000km warranty applies to the part as supplied, but warranty does not replace the need to confirm fitment. In alternator work, the practical checks are voltage, amperage, pulley section, mounting configuration, and connector type, especially when replacing an OE-style charging unit.

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 A4TUG081AMA 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. A4TUG081AMA, Brand MITSUBISHI, Description Mitsubishi Alternator 24V 80A, Adjusting Hole Diameter M12x1.25, Pin Code IR18, Pulley Outside Diameter 65mm, Regulator Type Internal, Voltage 24, Mount Cnt to Cnt 190mm.

Mitsubishi Alternator 24V 80A. Part number A4TUG081AMA should be checked first. Listed voltage is 24. 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 6 Groove. Those physical and electrical details should line up with the original unit before the replacement is approved for fitment.

For part number A4TUG081AMA, 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 24 and output 80 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Where no verified application list is available, the part number, mounting details, connector style, and published specifications should be used as the primary selection criteria.

In the absence of a verified fitment list, the safest approach is to compare the removed unit directly with the listed product details. That includes checking the housing style, pulley layout, regulator arrangement, and any visible identification numbers before supply is approved.

The listed warranty is 2 Years 400,000km. Warranty terms should be considered alongside correct application and part identification, as warranty does not replace fitment confirmation.

Compatibility note: Confirm compatibility using part number A4TUG081AMA, 24V system voltage, 80A output, twin leg mounting, 6 groove pulley, and the listed mounting dimensions before purchase.
