Mahle Alternator 12V 100A MG620 New Internal Regulator CW

This Mahle alternator is a 12V, 100A unit supplied new, with part number MG620 and a one year warranty. It is listed with an internal regulator, clockwise rotation, and a single-leg alternator mount, so it suits applications that match those specific electrical and mounting details.

The pulley setup is supplied with a belt pulley, 72mm pulley outside diameter, B section pulley, and one belt. Mounting dimensions provided include 56mm mount leg thickness, 56.0 mounting bores distance, 144mm mount centre to centre, and 8mm pivot and adjusting hole diameters. Those measurements are the practical checks that matter when confirming replacement fitment.

It is noted with a dust cover and a pin code of IR200. The unit is identified as Mahle brand, new rather than remanufactured, and the weight is listed at 5.44kg. For buyers replacing an alternator in compact equipment or machinery, matching the mounting arrangement and regulator type is just as important as matching the 12V and 100A electrical rating.

Application and Buying Notes

Before ordering, compare the part number MG620, the 12V system voltage, and the 100A charge current against the alternator you are replacing. The mounting arrangement also needs to line up: this unit is listed with a single-leg mount, 56mm mount leg thickness, 56.0 mounting bores distance, and 144mm mount centre to centre.

The pulley details are equally important. This alternator uses a 72mm outside diameter pulley with a B section profile and one belt, so the belt type and pulley size should be checked against the machine before purchase. A mismatch here can prevent correct belt alignment or installation even when the electrical rating appears similar.

Regulator type is another key checkpoint. This alternator has an internal regulator, so it should only be considered where that configuration matches the application. The unit is also listed with clockwise rotation, which must align with the original component’s rotation requirement.

Fitment references include AVANT, JCB, MULTIONE, VERMEER, and WACKER NEUSON applications, but the safest approach is still to verify by part number and the physical measurements. Equipment variations can occur within the same family, so confirm the alternator mount, pulley section, and hole diameters before finalising the order.

The unit is supplied new, not remanufactured, and carries a one year warranty. Weight is listed at 5.44kg and the alternator includes a dust cover, which may help when comparing packaging, handling, and the general construction of the replacement part.

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 MG620 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 100A. Part number MG620 should be checked first. Listed voltage is 12. Listed output rating is 100. 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 B. Those physical and electrical details should line up with the original unit before the replacement is approved for fitment.

For part number MG620, 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 100 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Available application references include AVANT 755I, AVANT 755I 2015, AVANT 760I, AVANT 760I 2015, JCB 406ZX, JCB 406ZX 2016. 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 MG620, 12V, 100A, internal regulator, clockwise rotation, single-leg mount, pulley details, and the listed mounting measurements with the existing alternator and machine application before ordering.
