Mahle Alternator 12V 120A MG404

The Mahle MG404 is a 12V alternator rated at 120A, supplied as an each unit for rotating electrical applications. It is identified in the supplied details as MAHLE brand, part number MG404, with a one year warranty.

This alternator is listed with a V-ribbed belt pulley and an 8-belt arrangement, with a connecting angle of 60.0 degrees. Key mounting figures provided are 81.0 mm mounting bores distance and 86.0 mm mounting points diameter, so these dimensions are important when checking against the existing unit before ordering.

The stated distance from pulley to alternator is 32.7, and the net weight is 5890. Those figures, together with the 12 volt and 120 amp rating, help confirm whether the unit matches the electrical and physical requirements of the application.

The product is also described as meeting international standards and requirements for electromagnetic compatibility, and as being manufactured using environmentally friendly technologies and materials. That is useful context, but the correct part number and application details should still be checked carefully before purchase.

Application and Buying Notes

Before ordering, compare the existing alternator’s part number, pulley type, and mounting dimensions with MG404. The supplied figures of 81.0 mm mounting bores distance, 86.0 mm mounting points diameter, and 32.7 distance from pulley to alternator are the most useful checks when matching a replacement.

The electrical specification matters as much as the physical fit. This unit is rated at 12V and 120A, so it should only be considered where the charging system specification calls for that output level and the surrounding components are suitable for a V-ribbed belt pulley with an 8-belt setup.

If the machine is one of the reported CASE IH MAXXUM or NEW HOLLAND TM applications, treat that as a starting point rather than a final confirmation. Model naming and build year are not enough on their own, because alternator fit can vary with charging system setup and bracket details.

The one year warranty provides a clear purchase reference, but warranty cover does not replace fitment checking. Matching the part number MG404 and confirming the pulley, mounting points, and voltage/amperage specification remains the safest approach before 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 MG404 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, Suits Unit Make Mahle, Alternator Charge Current [A] 120, Mounting Bores Distance 81.0, Mounting points diameter 86.0, Distance from pulley to the alternator 32.7, Packaging width 18.60, Net Weight 5890.

Additional published details for cross-checking include Product Group 1 ROTATING ELECTRICAL, Part No. MG404, Brand MAHLE, Description Mahle Alternator 12V 120A, Power Rating (Amp) 120, Voltage 12, Pulleys with V-ribbed belt pulley, Connecting Angle [Degree] 60.0, Number of belts 8, Packaging length 24.8.

Mahle Alternator 12V 120A. Part number MG404 should be checked first. Listed voltage is 12. Listed output rating is 120. These details form the core reference points used by parts interpreters when confirming the correct replacement.

For part number MG404, 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 120 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Available application references include CASE IH MAXXUM, CASE IH MAXXUM 2002, CASE IH MAXXUM 2003, CASE IH MAXXUM 2004, NEW HOLLAND TM, NEW HOLLAND TM 2000. 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.

Compatibility note: Please confirm compatibility using part number MG404, the 12V 120A specification, the V-ribbed belt pulley, and the stated mounting dimensions before ordering. Reported fitment includes selected CASE IH MAXXUM and NEW HOLLAND TM applications, but final fitment should be verified against the vehicle and existing unit.
