Mahle Alternator 24V 80A MG442

The MAHLE MG442 alternator is a new 24V, 80A rotating electrical unit supplied each, with an internal regulator and a clockwise rotation. It is listed with a single-leg alternator mount, 195mm mount centre to centre, and a mounting bores distance of 50.8mm, so those dimensions matter when checking whether it suits your application.

Key identifiers on this unit include Part No. MG442, OEM Number 11.209.416, and Pin Code IR165. It is specified with a connector / clamp of W, a shaft diameter of 17mm, and a pulley arrangement listed as without belt pulley, so it is important to compare the full mounting and drive details before ordering.

This alternator is described as a Mahle unit with a 24V system voltage and 80 amp charge current. It is supplied with an internal regulator and is noted as compliant with international standards for electromagnetic compatibility, manufactured using the latest technologies and materials, and ISO 9001 certified.

Application and Buying Notes

Before ordering, compare the part number MG442 and OEM Number 11.209.416 against the unit you are replacing. The physical details also need to line up: 24V voltage, 80A charge current, clockwise rotation, internal regulator, single-leg mount, 195mm mount centre to centre, and a 17mm shaft diameter are all relevant checks for this alternator.

The pulley arrangement is listed as without belt pulley, which means you should confirm whether your existing drive setup is intended to reuse a pulley or whether your application requires a different arrangement. The connector / clamp is W, the pivot hole diameter is 14, the adjusting hole diameter is 8, and the mounting points diameter is 99.0, so matching the mounting interface is just as important as matching the electrical rating.

The fitment references supplied for this alternator include a number of VOLVO applications, but the list is broad and should be treated as a guide only. Exact suitability still depends on the engine, charging system layout, regulator arrangement, pulley setup, and mounting dimensions on the vehicle or machine in front of you.

If you are replacing an alternator on a Volvo vehicle, construction machine, or marine / Penta application, check the old unit carefully for labels, terminals, bracket style, and shaft or pulley dimensions before purchase. Even where the model family appears in the fitment references, the safest approach is to match the part number and the mounting measurements first.

The unit is supplied new and carries a one year warranty, which is useful for peace of mind, but it does not replace the need to verify compatibility. Alternators can look similar while differing in regulator type, rotation, output, connector style, or mount dimensions, and those differences matter during installation.

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 MG442 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 One Year, Mount Leg Thickness 51mm, Pivot Hole Diameter 14, Pulley Section Not Applicable, Rotation CW, Suits Unit Make Mahle, Alternator Mount Single Leg, Mount Cnt to Cnt 195mm.

Additional published details for cross-checking include OEM Number 11.209.416, Pulleys without belt pulley, Mounting Bores Distance 50.8, Packaging length 24.8, Packaging height 17.50, Product Group 1 ROTATING ELECTRICAL, Part No. MG442, Brand MAHLE, Description Mahle Alternator 24V 80A, Adjusting Hole Diameter 8.

Mahle Alternator 24V 80A. Part number MG442 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 Single Leg. Regulator type is Internal. Pulley configuration is Not Applicable. Those physical and electrical details should line up with the original unit before the replacement is approved for fitment.

For part number MG442, 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.

Compatibility note: Confirm fitment using Part No. MG442, OEM Number 11.209.416, the listed 24V 80A specification, and the mounting details before ordering. The Volvo references are application guides only and should be checked against the vehicle or machine in front of you.
