Mahle Alternator 12V 120A MG268 | OEM 11204413 | 8 Groove V-ribbed Pulley

This MAHLE alternator is a new 12V unit rated at 120A, supplied as part number MG268 and cross-referenced to OEM number 11204413. It uses an internal regulator, a CW rotation, and a V-ribbed pulley with 8 grooves, so the mounting and belt match need to be checked carefully before purchase.

It is listed as a single-leg alternator mount with a 51mm mount leg thickness, 50.8 mounting bores distance, and 86.0 mounting points diameter. The pulley outside diameter is 60mm, and the distance from the pulley to the alternator is 27.2, which are useful checks when comparing against the original unit.

For buyers replacing a charging unit on compatible machinery, the key identifiers here are MAHLE, MG268, 12V, 120A, and OEM 11204413. The alternator is sold as each, with one-year warranty cover, and it is specified with connector / clamp W and adjuster hole diameter M8x1.25.

Application and Buying Notes

When replacing an alternator, the most reliable checks are the part number, OEM number, mount style, pulley configuration, and electrical specification. This unit is identified as MG268 and OEM 11204413, with a 12V, 120A rating, so it should only be compared with the original charging unit where those details align.

The mounting pattern matters just as much as the electrical output. This alternator is a single-leg mount with 51mm mount leg thickness, 50.8 mounting bores distance, 86.0 mounting points diameter, and a 10mm pivot hole diameter. If any of those measurements differ from the removed unit, fitment should be checked again before fitting.

Belt drive compatibility also needs attention because this alternator uses an 8 groove V-ribbed pulley with a 60mm outside diameter and CW rotation. Those details are important when comparing pulley alignment, belt type, and drive direction on the machine.

If you are replacing a failed alternator, check the connector style as well. This unit is listed with connector / clamp W and an M8x1.25 adjusting hole, which can affect how it mounts and connects in the application. A quick comparison with the existing alternator is the safest way to avoid an incorrect order.

The supplied applications point to JOHN DEERE machinery, including 540G III and 548G III variants, plus A400 and R450 listings. Even where a model family appears in the fitment data, it is still best practice to confirm the exact application using the OEM number, alternator mounting points, and pulley section before purchase.

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 MG268 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.

Mahle Alternator 12V 120A. Part number MG268 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.

Mount style is Single Leg. Regulator type is Internal. Pulley configuration is 8 Groove. Those physical and electrical details should line up with the original unit before the replacement is approved for fitment.

For part number MG268, 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 JOHN DEERE 540G III, JOHN DEERE 540G III 2005, JOHN DEERE 540G III 2006, JOHN DEERE 540G III 2007. 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 fitment by checking part number MG268, OEM number 11204413, the 12V 120A specification, and the mounting and pulley details against the original alternator in your machine before ordering.
