Mitsubishi Alternator 24V 100A A4TRG691AMA

The Mitsubishi A4TRG691AMA alternator is a new 24V, 100A unit supplied as an OE product for applications that use a pad-mount alternator layout. It suits Mitsubishi units and is identified by part number A4TRG691AMA, with an internal regulator and IR98 pin code.

This alternator uses a 10 groove pulley with an 88mm outside diameter, 8mm mount hole diameter, 87mm mount leg thickness, and 157mm mount centre-to-centre measurement. Those dimensions matter when matching the alternator to the bracket, pulley alignment, and belt setup on the vehicle.

At 7.42kg, this is a rotating electrical component built for proper system matching rather than a universal fit. The listed warranty is 2 years or 400,000km, which gives a clear service-life reference for buyers comparing replacement options for 24V charging systems.

Application and Buying Notes

Before ordering, check the part number A4TRG691AMA against the existing unit or parts record, then compare the alternator mount type, pulley section, and regulator type. This alternator is a 24V, 100A pad-mount unit with an internal regulator, so those details need to line up with the vehicle’s charging system setup.

The pulley and mounting dimensions are important on this unit: 10 groove pulley, 88mm pulley outside diameter, 8mm mount hole diameter, 87mm mount leg thickness, and 157mm mount centre-to-centre. If any one of those points differs from the original alternator, the unit may not physically install or align correctly.

Because the fitment references cover several heavy vehicle and machinery applications, it is best to confirm the exact model, year, and original alternator details rather than rely on vehicle family alone. The supplied application groups include Doosan/Daewoo, Irizar and Scania references, but the safest check remains the part number and the measured mounting information.

This alternator is listed as new and supplied as an OE product, which makes it suitable for buyers looking for a direct replacement style part rather than a remanufactured unit. The 2 year or 400,000km warranty gives an added reference point, but it does not replace the need to confirm the installation details on the vehicle.

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 A4TRG691AMA 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.

Relevant published details for this unit include Type ALTERNATOR, Unit of Measure EACH, Warranty 2 Years 400,000km, Mount Leg Thickness 87mm, Power Rating (Amp) 100, Pulley Section 10 Groove, Suits Unit Make Mitsubishi, Alternator Mount Pad, New / Reman. New.

Additional published details for cross-checking include Product Group 2 ALTERNATORS, Part No. A4TRG691AMA, Brand MITSUBISHI, Description Mitsubishi Alternator 24V 100A, Mount Hole Diameter 8, Pin Code IR98, Pulley Outside Diameter 88mm, Regulator Type Internal, Voltage 24, Mount Cnt to Cnt 157mm.

Mitsubishi Alternator 24V 100A. Part number A4TRG691AMA should be checked first. Listed voltage is 24. Listed output rating is 100. These details form the core reference points used by parts interpreters when confirming the correct replacement.

Mount style is Pad. Regulator type is Internal. Pulley configuration is 10 Groove. Those physical and electrical details should line up with the original unit before the replacement is approved for fitment.

For part number A4TRG691AMA, 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 100 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Available application references include DOOSAN/DAEWOO DA30, DOOSAN/DAEWOO DA30 2013, DOOSAN/DAEWOO DA40, DOOSAN/DAEWOO DA40 2013, IRIZAR CENTURY, IRIZAR CENTURY 2010. 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 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 by matching part number A4TRG691AMA, 24V voltage, 100A output, pad mount style, internal regulator, IR98 pin code, and the listed pulley and mounting measurements against the original unit before purchase.
