Bosch Alternator 12V 110A 0124325122

The Bosch Alternator 12V 110A, part number 0124325122, is a new alternator supplied as a single unit and specified with an internal regulator. It is rated at 12 volts and 110 amps, with an alternator charge current listed at 115 A, making it a practical replacement where the original application matches these electrical and mounting details.

This unit uses a Twin Leg alternator mount and a Double Pivot Lever fastening type, and it is listed as a bi-directional rotation alternator. It is also described as an alternator excl. vacuum pump, so the presence or absence of a vacuum pump arrangement needs to be checked against the vehicle’s original setup before ordering.

Bosch identifies this alternator under product group Rotating Electrical and Alternators, with pin code IR155 and suit unit make Bosch. The unit is backed by a one year warranty, and Bosch lists recommended additional repairs as the V-Belt/V-Ribbed Belt when carrying out the replacement.

Application and Buying Notes

Before ordering, confirm the part number 0124325122 against the alternator currently fitted to the vehicle. The most important checks here are 12V system voltage, 110A power rating, Twin Leg mounting, Double Pivot Lever fastening type, and the IR155 pin code where it is used as part of the identification process.

Because this alternator is listed as bi-directional and as an alternator excl. vacuum pump, the vehicle’s original alternator design needs to be matched carefully. Those details can affect whether the unit fits correctly and functions as intended, even where the electrical output appears similar.

Bosch also notes a recommended additional repair of the V-Belt/V-Ribbed Belt. In practice, that means it is sensible to inspect the drive belt condition at the same time, especially if the current belt shows wear, glazing, cracking, or contamination. The alternator itself is new and has an internal regulator, so the surrounding charging system condition still matters.

If you are replacing a worn alternator, compare the original unit’s mounting points, regulator type, and any pump arrangement before fitting. A correct match should align on the physical mount, electrical output, and part number rather than relying on appearance alone.

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 0124325122 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.
