Mahle Alternator 12V 200A MG481

The Mahle MG481 is a new 12V alternator with a 200A charge rating, internal regulator, and a twin leg alternator mount. It is listed with a V-ribbed belt pulley, 8 groove pulley section, clockwise rotation, and a dust-proof construction note, making the mounting and drive details worth checking carefully against the unit you are replacing.

Key identifiers on this unit include Part No. MG481, pin code IR189, and series AAN. The alternator uses an 82mm inside mounting leg measurement, 148mm centre-to-centre mounting, an 8mm pivot hole diameter, and an M8x1.25 adjusting hole, so matching the physical dimensions is just as important as matching the electrical rating.

This alternator is a Mahle-branded unit suited to Mahle applications, with a coil on the D+ terminal noted in the product details. It is supplied as a new unit, not remanufactured, and carries a one year warranty.

For buyers replacing a heavy-duty charging unit, the important checks are simple: 12V system voltage, 200A output, pulley type, mounting leg spacing, rotation, and the part number MG481. Those details help confirm whether the alternator will physically and electrically suit the vehicle before fitting begins.

Application and Buying Notes

Before ordering, confirm the part number MG481 and compare the mounting details to your original alternator. The listed twin leg mount, 82mm inside mounting legs, 148mm centre-to-centre mounting, 8mm pivot hole, and M8x1.25 adjusting hole need to line up with the vehicle’s existing setup for a proper installation.

The electrical side also matters. This alternator is rated at 12V and 200A, with an internal regulator and a coil on the D+ terminal. If the original unit uses a different voltage, regulator arrangement, terminal style, or charge output, it should be checked against the vehicle specification before purchase.

Pulley and belt details should be matched as carefully as the mounting points. This unit is listed with a V-ribbed belt pulley, 8 groove pulley section, 61mm pulley outside diameter, and clockwise rotation. If the belt profile, groove count, or rotation differs from the original alternator, fitment should be verified before installation.

The fitment list shows applications across Case IH, New Holland, and Steyr ranges, including Maxxum, Puma, T6, T7, T7000, T8, T9, CVT, and Profi families. Even where a model name appears in the application list, the safest approach is still to confirm the exact part number and the mounting and pulley measurements on the vehicle.

This is a new alternator, not a remanufactured unit, and it is supplied with a one year warranty. That makes it a straightforward replacement option when the existing charging system uses the same 12V, 200A specification and the same physical layout.

If you are replacing a charging unit that has failed, it is worth checking the connector arrangement, the terminal details, and the drive belt condition at the same time. A worn pulley, stretched belt, or mismatched mounting can create problems even when the alternator rating is correct.

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 MG481 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 200A. Part number MG481 should be checked first. Listed voltage is 12. Listed output rating is 200. 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 8 Groove. Those physical and electrical details should line up with the original unit before the replacement is approved for fitment.

For part number MG481, 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 by matching part number MG481, the 12V 200A specification, twin leg mount dimensions, 8 groove V-ribbed pulley, clockwise rotation, and the listed application details before ordering.
