Bosch Alternator 12V 120A 0124515198

This Bosch alternator is a 12V, 120A unit with part number 0124515198. It is listed as a new alternator with an internal regulator, pad mount, direct fastening, and a free-wheel belt pulley. Those details matter when matching the unit to the vehicle, because the mounting style, pulley type, and electrical output all need to align with the original application.

It is identified as alternator type excl. vacuum pump, with a 7 groove pulley section and a 56mm pulley outside diameter. The alternator charge current is 120A and the voltage is 12V, so it suits a vehicle electrical system designed around those specifications. The unit is made by Bosch and carries a one year warranty.

The packaging dimensions are 23.9 x 20 x 20, and the unit is manufactured in South Africa. Additional listed features include corrosion resistance, high quality raw materials for long life and optimal performance, and a reduction drive designed to maintain continual speeds for easier starting. As with any charging system component, matching the part number and configuration is the safest way to order correctly.

Application and Buying Notes

Before ordering, confirm the original alternator is a 12V unit with 120A output and compare the mounting arrangement. This Bosch unit is a pad mount design with direct fastening, and it uses a 7 groove pulley with a 56mm outside diameter. If the existing alternator has a different mount style or pulley setup, it is not a like-for-like replacement.

The unit is listed as alternator type excl. vacuum pump, so that detail should be checked against the vehicle’s original arrangement. The internal regulator is also an important match point, because regulator type is part of the alternator’s configuration and cannot be assumed to be interchangeable across different versions. The part number 0124515198 is the strongest identifier to use when checking compatibility.

If you are replacing the alternator because of charging faults, it is sensible to inspect the belt system at the same time. The listed recommended additional repair is V-Belt / V-Ribbed Belt, which can help avoid fitting a new alternator against a worn drive belt. A correct installation also depends on the pulley and belt alignment matching the vehicle’s existing setup.

The packaging size is 23.9 x 20 x 20, which is useful for planning shipping, storage, and workshop handling. This is a new Bosch alternator and it carries a one year warranty, but warranty coverage does not replace the need to confirm the part number, voltage, amperage, mount, and pulley details before installation.

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 0124515198 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.

For part number 0124515198, 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 120 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Compatibility note: Please confirm compatibility using Bosch part number 0124515198, the 12V 120A rating, the pad mount/direct fastening arrangement, and the 7 groove free-wheel pulley configuration before ordering.
