Mahle Alternator 12V 120A MG597 New, Internal Regulator, CW

The Mahle alternator listed here is a 12V, 120A unit, part number MG597, supplied new and sold each. It is specified with a single leg mount, internal regulator, clockwise rotation, and no belt pulley fitted, so it suits applications that match those exact mounting and drive details.

Key physical points for checking up front are the 56mm mount leg thickness, 56.0mm mounting bores distance, 143mm mount centre to centre, 8mm pivot hole diameter, 8mm adjusting hole diameter, and 17mm shaft diameter. The connector/clamp is W and the connecting angle is 60.0 degrees.

This alternator is described as dust proof and the product notes also state that alternators fulfil international standards and requirements for electromagnetic compatibility, and are manufactured using environmentally friendly technologies and materials. The unit is covered by a one year warranty.

Because alternators are normally matched by more than one detail at once, the safest purchase check is part number MG597 together with voltage, amperage, rotation, pulley setup, and mounting measurements. That approach is especially important when replacing an existing Mahle unit or a unit with the same 12V 120A output.

Application and Buying Notes

Before ordering, compare MG597 with the alternator already fitted to the machine. The important match points here are 12V charging, 120A output, clockwise rotation, internal regulator, single leg mount, and the absence of a belt pulley. If any one of those differs, the part may not be the correct replacement even if the alternator looks similar.

Mounting measurements matter as much as the electrical rating. Check the 56mm mount leg thickness, 56.0mm mounting bores distance, 143mm mount centre to centre, 8mm pivot hole, 8mm adjusting hole, and 17mm shaft diameter against the existing unit and the bracket space available on the vehicle.

The connector/clamp is listed as W and the connecting angle is 60.0 degrees, so the plug position and cable routing should also be confirmed before purchase. On equipment where access is tight, those details can affect how the alternator sits and how the harness reaches the connection point.

If you are replacing a Mahle alternator, the part number MG597 is the strongest identifier to use. It is still sensible to check the full application details, because alternator fitment is often determined by several features together rather than by output alone.

This is a new alternator, not a remanufactured unit, and it weighs 5.12kg. That weight and the stated physical dimensions may help when comparing the part on the bench with the removed unit, especially if the previous alternator carried a pulley or had a different mounting leg arrangement.

The product notes describe the unit as dust proof and covered by a one year warranty. Those are useful ownership details, but they do not replace the need to confirm the electrical and mechanical match to the vehicle or machine 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 MG597 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.

Additional published details for cross-checking include Alternator Charge Current [A] 120, Connector / Clamp W, Connecting Angle [Degree] 60.0, Packaging length 24.8, Packaging height 17.50, Weight 5.12kg, Product Group 1 ROTATING ELECTRICAL, Part No. MG597, Brand MAHLE, Description Mahle Alternator 12V 120A.

Mahle Alternator 12V 120A. Part number MG597 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 Not Applicable. Those physical and electrical details should line up with the original unit before the replacement is approved for fitment.

For part number MG597, 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.

Compatibility note: Confirm fitment using part number MG597, the 12V 120A specification, clockwise rotation, internal regulator, single leg mount, and the listed mounting and connector details before purchase. Where any measurement or connection point does not match the existing alternator, treat the application as unconfirmed.
