Mahle Alternator 24V 55A MG245

The MAHLE Alternator MG245 is a new 24V, 55A unit supplied with a belt pulley and internal regulator. It is listed as a single-leg alternator with clockwise rotation, and it carries a one year warranty.

Key mounting and pulley details matter on this unit. The mounting leg thickness is 56mm, the mount centre to centre is 144mm, the pulley outside diameter is 72mm, and it uses one belt with an A section pulley.

This alternator is noted as dust proof and is described as meeting international standards and requirements for electromagnetic compatibility. It is also manufactured using environmentally friendly technologies and materials, which may be relevant for buyers who value a modern replacement unit with defined electrical and mounting details.

Fitment guidance

• Fitment is not model-specific here, so confirm the part number MG245 against your existing alternator and application details before ordering.
• Supplied fitment references include machinery and construction applications from Atlas Copco, Bomag, Case, Deutz, Dynapac, Hamm, Liebherr, MWM, Tamrock, Volvo Construction, and Wirtgen.
• Sample application references include Atlas Copco PR 425, Bomag BW151AD2, Case A220, Deutz BF4L1011F, Deutz F5L912F, Deutz F6L413, Deutz F6L912, Deutz F6L913, Dynapac CC222HF/CHF, Dynapac CC232CHF, Dynapac CC322, Hamm HW90B, Liebherr A901B, Liebherr R961, Liebherr R971, Liebherr R981, MWM D226-2, Tamrock 206T, Tamrock TORO 0151, Volvo Construction L30B, Volvo Construction L30B-Z-SX, Volvo Construction L32B, Volvo Construction L35, Wirtgen W100, Wirtgen W100R, and Wirtgen W120R.
• Year references appear in the fitment data for some applications, including 1972 through 2016 on selected models.
• Because alternators are matched by electrical output, pulley arrangement, mount style, and dimensions, check the 24V system, 55A rating, single-leg mount, 72mm pulley diameter, and 56mm mount leg thickness against the removed unit.

Application and Buying Notes

Before buying, compare the MG245 part number with the alternator already fitted to the machine. The listed 24V, 55A output, internal regulator, clockwise rotation, and single-leg mounting style all need to match the application, not just the general make of equipment.

The pulley setup is just as important as the electrical rating. This unit is supplied with a belt pulley, uses an A section pulley, takes one belt, and has a 72mm pulley outside diameter, so it should only be considered where those measurements align with the existing drive arrangement.

Mounting dimensions should be checked carefully. The mount leg thickness is 56mm, the mount centre to centre is 144mm, the mounting bores distance is 56.0, the adjusting hole diameter is 8, the pivot hole diameter is 8, and the mounting points diameter is 86.0.

If you are replacing a dust proof alternator in a machine used in demanding conditions, confirm the physical fit and electrical specification together. The fact that this unit is new and supplied with an internal regulator does not remove the need to match the installed setup, especially where the machine uses a specific bracket arrangement or wiring configuration.

The one year warranty applies to the supplied unit, but warranty support does not replace fitment checking. A correct match still depends on the vehicle or machine application, the part number, and the measured dimensions from the removed alternator.

Use the application references only as a guide to where the part has been listed. Final confirmation should always come from the part number MG245, the 24V 55A specification, and the physical alternator dimensions on your machine.

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 MG245 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 MG245 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 MG245, 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 compatibility by checking part number MG245, 24V system voltage, 55A output, single-leg mounting, CW rotation, internal regulator, and the listed pulley and mounting dimensions against the existing alternator before purchase.
