Application and Buying Notes

Before ordering, match the alternator mount style, the 73mm inside mounting legs, and the 166mm mount centre to centre measurement against the vehicle or equipment already fitted. The listed 12V, 65A rating and internal regulator mean it should be compared carefully with the existing charging unit rather than selected on appearance alone.

The pulley setup also matters. This unit is listed with a double pulley, AA pulley section, 88mm pulley outside diameter, and support for 2 belts. If the current alternator uses a different pulley profile or belt arrangement, the unit may not be a direct swap even where the make or model family appears similar.

Part number MG524 is the most reliable reference to check alongside the mounting bores distance of 70.0, mounting points diameter of 85.0, pivot hole diameter of 12, and adjusting hole diameter of 11. Those measurements help confirm whether the alternator will physically bolt up without modification.

This alternator is a new MAHLE unit, so it is suitable for buyers wanting a replacement rather than a remanufactured component. The one year warranty provides a defined warranty period, but correct application matching remains important because alternator fitment is governed by the charging system layout, pulley setup, and mounting geometry.

If you are replacing an older alternator, compare the existing unit’s output rating, voltage, regulator type, and pulley arrangement before purchase. Even within the same tractor or equipment family, alternator variants can differ in mounting points, belt count, or pulley offset.

For best results, confirm the application using the part number MG524 and the listed fitment references together. Where the existing unit is missing, damaged, or unreadable, the physical measurements become especially important for checking compatibility before the alternator is installed.

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 MG524 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 12V 65A. Part number MG524 should be checked first. Listed voltage is 12. Listed output rating is 65. These details form the core reference points used by parts interpreters when confirming the correct replacement.

Mount style is Twin Leg. Regulator type is Internal. Pulley configuration is AA. Those physical and electrical details should line up with the original unit before the replacement is approved for fitment.

For part number MG524, 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 65 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Available application references include AGCO ALLIS 8610, AGCO ALLIS 8610 1991, AGCO ALLIS 8630, AGCO ALLIS 8630 1991, CASE IH 2120, CASE IH 2120 1988. 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 checking MAHLE part number MG524 against the existing alternator, then compare the listed voltage, 65A output, twin leg mount, double pulley, and all mounting measurements before ordering.
