Mitsubishi Alternator 24V 110A A4TR5591AMA

The Mitsubishi Alternator A4TR5591AMA is a new 24V, 110A unit supplied as each and identified as part number A4TR5591AMA. It is listed with an internal regulator, Twin Leg alternator mount, 8 groove pulley, and a pulley outside diameter of 82mm.

This alternator is described as a Mitsubishi unit and suits Mitsubishi applications. Key mounting measurements supplied are 104mm between the inside mounting legs, 198mm mount centre to centre, a 13mm pivot hole diameter, and an 11mm adjusting hole diameter. Those dimensions matter when comparing against the existing alternator before ordering.

The unit weighs 7.52kg and is specified with a low-noise design focus, including reduced wind and electromagnetic noise. The listed feature set also notes small size/high output and a minimum number of parts, which are practical points to check when matching a replacement alternator to an existing electrical system.

Application and Buying Notes

This alternator is a 24V, 110A unit with an internal regulator, so the first check is whether the vehicle or equipment uses the same charging system voltage and mounting arrangement. The supplied dimensions — 104mm inside mounting legs, 198mm mount centre to centre, 13mm pivot hole diameter, and 11mm adjusting hole diameter — should be compared directly with the removed unit.

The 8 groove pulley and 82mm pulley outside diameter are important when matching belt alignment and pulley style. If the existing alternator uses a different pulley section or a different mounting style, the part may not line up correctly even if the connector appears similar.

This unit is listed as a Mitsubishi alternator with part number A4TR5591AMA and pin code IR154. The part number is the most reliable reference point for ordering, particularly where multiple alternators may look alike but differ in output, regulator type, or mounting details.

At 7.52kg, this is not a lightweight accessory item, so handle and install it with proper support during fitting. It is supplied new and carries a 2 Years / 400,000km warranty, which gives a clear service-life expectation, but the alternator still needs to be matched correctly to the application for the warranty and installation to make sense in practice.

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 A4TR5591AMA 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.
