Mahle Alternator 24V 55A MG289

The MAHLE MG289 alternator is a new 24V unit rated at 55A, supplied as each and listed with an internal regulator. It is a single-leg alternator with a CW rotation and comes without a belt pulley, so the drive arrangement on the vehicle needs to suit that layout.

Physical mounting details are important on this unit. Key measurements include 151mm mount centres A, 150mm mount centre to centre, 80.0mm mounting bores distance, 80mm mount leg thickness, a 10mm pivot hole diameter, a 12mm adjusting hole diameter, and a 17mm shaft diameter. The connector/clamp is W, and the connecting angle is 60.0 degrees.

This alternator is noted as dust proof and carries one year warranty coverage. It is also listed with a 24V electrical system and 55A charge current, which makes the voltage and output rating straightforward to check against the vehicle’s original charging setup before ordering.

MAHLE states that its alternators fulfil international standards and electromagnetic compatibility requirements and are manufactured using environmentally friendly technologies and materials. Those points are useful for buyers who want a replacement part that matches the original system specification without changing the vehicle’s electrical design.

Application and Buying Notes

Before ordering, compare the MG289 part number, 24V system voltage, 55A output, and internal regulator type with the unit being replaced. Those four details are the quickest way to narrow down whether this alternator is the correct style for the application.

The mounting and drive arrangement also need to line up. This alternator is a single-leg unit with CW rotation, no belt pulley, a 17mm shaft diameter, and mount measurements including 151mm mount centres A, 150mm mount centre to centre, and 80.0mm mounting bores distance. If any of those figures differ from the existing alternator or bracket, the part may not physically install correctly.

Because fitment is application-specific, use the listed vehicle groups only as a guide and check the exact machine model, year, and engine or charging setup where relevant. The product data includes a wide range of machinery and truck applications, but the final match still depends on the original alternator configuration in the vehicle.

If you are replacing a failed alternator, it is worth checking the connector style as well. This unit uses a W connector/clamp and a 60.0 degree connecting angle, so the plug orientation and harness alignment should be compared carefully before purchase.

The one year warranty gives a clear reference for coverage, but it does not replace fitment confirmation. A careful comparison of part number, mounting dimensions, regulator type, and pulley arrangement is the safest way to avoid delays and return freight on a charging-system part.

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 MG289 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 Centres A 151mm, Pivot Hole Diameter 10, Pulley Section Not Applicable, Rotation CW, Suits Unit Make Mahle, Note Dust proof, Mount Cnt to Cnt 150mm.

Additional published details for cross-checking include Alternator Charge Current [A] 55, Connector / Clamp W, Connecting Angle [Degree] 60.0, Packaging length 24.8, Packaging height 17.50, Product Group 2 ALTERNATORS, Part No. MG289, Brand MAHLE, Description Mahle Alternator 24V 55A.

Mahle Alternator 24V 55A. Part number MG289 should be checked first. Listed voltage is 24. Listed output rating is 55. 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 MG289, 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 55 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Available application references include CASE W18, CASE W18 1993, CASE W20, CASE W20 1993, DAF 85 CF, DAF 85 CF 1998. 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 MG289 part number, 24V voltage, 55A output, internal regulator, CW rotation, single-leg mount, and the listed mounting dimensions to the original unit before ordering.
