Mahle Alternator 24V 50A MG84 New Dust Proof Internal Regulator CW

The MAHLE Alternator MG84 is a new 24V unit rated at 50A, supplied as each and covered by a one year warranty. It is listed as dust proof, with a CW rotation and an internal regulator, which are key checks when matching alternators to a machine’s charging system.

This alternator is supplied without a belt pulley and uses a single leg mount. The listed mount leg thickness is 51mm, with a mount centre-to-centre measurement of 173mm, pivot hole diameter of 10mm, and mounting bores distance of 50.8mm. Those dimensions matter when confirming the physical fit to the existing bracket and alignment points.

The part number is MG84 and the unit is identified as MAHLE with a 24V, 50A charge current rating. It also uses connector / clamp W, has a shaft diameter of 17mm, adjusting hole diameter M8x1.25, and mounting points diameter of 86.0, so it is best checked carefully against the removed unit before ordering.

Application and Buying Notes

Before ordering, confirm the removed alternator matches the key identifiers: MG84, MAHLE, 24V, 50A, CW rotation, and internal regulator. The mechanical checks are just as important, especially the single leg mount, 51mm mount leg thickness, 173mm mount centre-to-centre, 50.8mm mounting bores distance, and 10mm pivot hole diameter.

The alternator is supplied without a belt pulley, so the pulley arrangement on the machine must be checked separately. The shaft diameter is 17mm and the adjusting hole is M8x1.25, which should be compared against the original unit and mounting hardware before purchase.

Fitment references are listed across CASE, HITACHI, INTERNATIONAL HARVESTER, JOHN DEERE, KOMATSU, LIEBHERR, and NEW HOLLAND applications, but those names alone do not replace a physical part check. Matching the part number, regulator type, rotation, and mounting dimensions remains the safest way to confirm suitability.

If the machine has been converted, repaired, or fitted with a non-standard charging setup, the 24V and 50A specification should be checked carefully. The connector / clamp W and the dust proof note are useful identifiers, but they should be treated as matching points rather than assumptions that every listed application will be identical.

For a reliable changeover, compare the original unit side by side with this alternator where possible. The listed measurements, including the 86.0 mounting points diameter, 17mm shaft diameter, and 4632 net weight, provide a practical reference when confirming the replacement part 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 MG84 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 50A. Part number MG84 should be checked first. Listed voltage is 24. Listed output rating is 50. 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 MG84, 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 50 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Available application references include CASE 1150C, CASE 1150C 2007, CASE 1155D, CASE 1155D 2006, HITACHI LX150-3, HITACHI LX150-5. 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.

The listed warranty is One Year. Warranty terms should be considered alongside correct application and part identification, as warranty does not replace fitment confirmation.

Compatibility note: Confirm compatibility by matching the part number MG84, the 24V 50A rating, CW rotation, internal regulator, and the mounting dimensions against the removed alternator and machine application details before ordering.
