Mahle Alternator 12V 200A - MG29

The MAHLE alternator listed as Part No. MG29 is a new 12V unit rated at 200A, supplied as an alternator only and without a belt pulley. It uses an internal regulator, clockwise rotation, and a single-leg mount with 2 mounting bores, which makes the physical mounting details important when matching it to the original unit.

Key dimensions include a mount leg thickness of 56mm, mount centre-to-centre of 156mm, pivot hole diameter of 10mm, adjusting hole diameter of 10mm, shaft diameter of 17mm, and a shaft length of 26.5mm. The connector/clamp is W, and the unit is marked as suitable for Mahle applications.

This alternator is built for 12V electrical systems and carries a 200A charge current rating. The product is listed as new, with a one-year warranty, and the feature note states that internal fan alternators are specially designed for operation under adverse environmental conditions. Confirm the part number MG29 and compare all mounting and electrical details before ordering.

Application and Buying Notes

The most important checks on this alternator are the part number MG29, the 12V system voltage, and the 200A charge current rating. If the vehicle or machine uses a different output rating, different regulator type, or a different rotation direction, the unit may not be suitable even if it looks similar externally.

Physical fit should also be checked carefully. This unit has a single-leg mount, 2 mounting bores, 56mm mount leg thickness, 156mm mount centre-to-centre, 10mm pivot and adjusting holes, and a 17mm shaft diameter. Those measurements need to match the original alternator setup closely, especially where brackets and alignment are concerned.

Because this alternator is supplied without a belt pulley, the existing pulley arrangement needs to be confirmed before purchase. The connector/clamp is W, and the shaft length is 26.5mm, so the electrical plug style and front-end hardware should be compared with the original unit as part of the check.

The listed fitment groups are broad, covering several AMMANN, DEUTZ-FAHR, FENDT, JCB, JOHN DEERE, LAMBORGHINI, MASSEY FERGUSON, NEW HOLLAND, ROGATOR, SAME, and TEREX FUCHS applications. That said, the safest approach is always to verify the exact application, build details, and original alternator against MG29 before fitting.

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 MG29 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 56mm, Pivot Hole Diameter 10, Pulley Section Not Applicable, Rotation CW, Suits Unit Make Mahle, Note Shaft Length 26.5mm, Mount Cnt to Cnt 156mm.

Additional published details for cross-checking include Alternator Charge Current [A] 200, Connector / Clamp W, Mounting Bores Distance 56.0, Packaging length 24.8, Packaging height 17.50, Product Group 2 ALTERNATORS, Part No. MG29, Brand MAHLE, Description Mahle Alternator 12V 200A.

Mahle Alternator 12V 200A. Part number MG29 should be checked first. Listed voltage is 12. Listed output rating is 200. 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 MG29, 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 200 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Available application references include AMMANN ARS200, AMMANN ARS200 2015, AMMANN ARS220, AMMANN ARS220 2015, DEUTZ-FAHR AGROTRON L, DEUTZ-FAHR AGROTRON L 2011. 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: Confirm compatibility by matching the part number MG29, the 12V / 200A specification, the CW rotation, the single-leg mount with 2 bores, and the pulley-less configuration against the original alternator and vehicle application details.
