Mahle Alternator 24V 55A MG130

The MAHLE MG130 is a new 24V alternator with a 55A charge current and internal regulator. It is listed as a single leg mount unit with a belt pulley fitted, and the pulley section is A, which matters when matching the belt profile already used on the application.

Key physical details include a 70mm pulley outside diameter, 11.5mm pivot hole diameter, 166mm centre-to-centre mount spacing, and 50.8mm mounting bores distance. The unit also has a mount leg thickness of 50.8mm and a mounting points diameter of 86.0, so the installation points should be checked carefully before ordering.

This alternator is noted as dust proof and insulated return, and MAHLE states that its alternators fulfil international standards and requirements for electromagnetic compatibility. It is supplied as each unit and carries a one year warranty.

For buyers replacing an existing alternator, the part number MG130 is the most practical reference point, followed by the 24V electrical system, 55A output, rotation direction of clockwise, and the single belt arrangement. Those details are the main checks that should be matched against the vehicle or equipment already in service.

Application and Buying Notes

The safest way to select this alternator is to match the part number MG130 first, then confirm the 24V system, 55A output, internal regulator, and clockwise rotation. Those are the core electrical and mechanical identifiers that need to line up with the replacement unit already fitted.

The mounting measurements are just as important as the electrical rating. Check the single leg mount, 11.5mm pivot hole diameter, 166mm mount centre-to-centre, 50.8mm mounting bores distance, 50.8mm mount leg thickness, and 86.0 mounting points diameter before committing to purchase.

Belt alignment should also be confirmed. This unit is supplied with a pulley fitted, uses one belt, has a 70mm pulley outside diameter, and a pulley section of A, so the belt profile and pulley alignment should be consistent with the application.

The note of dust proof and insulated return can be useful when comparing with the existing alternator arrangement, but it should not replace a physical check. If the old unit is available, compare the housing, mounting ears, pulley setup, and wiring arrangement before installation.

Where fitment has been listed for a machine or engine family, treat it as a guide only. Matching the exact alternator reference, mount style, pulley details, and electrical output remains the most reliable way to avoid a mismatch, especially across Volvo construction and Volvo Marine/Penta applications.

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 MG130 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 24V 55A. Part number MG130 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 A. Those physical and electrical details should line up with the original unit before the replacement is approved for fitment.

For part number MG130, 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 HITACHI EH650, HITACHI EH650 2004, VOLVO CONSTRUCTION, VOLVO CONSTRUCTION L160, VOLVO CONSTRUCTION L160 1987, VOLVO D12A. 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 fitment by matching part number MG130, 24V system voltage, 55A output, single leg mount, clockwise rotation, and the pulley and mounting measurements against the unit already fitted to the machine or engine.
