Bosch Alternator 12V 150A Direct Fastening 6 Groove Free-wheel Pulley Part No. 0124615019

The Bosch alternator listed here is a 12V, 150A unit with part number 0124615019. It is a new alternator, made in Spain, and supplied as an each unit for vehicle electrical system replacement where the matching mounting, pulley, and regulator details are required.

This alternator uses a pad mount with direct fastening, internal regulator, and a 6 groove pulley. It is listed as an alternator type excluding vacuum pump, so it suits applications that specifically call for that configuration rather than a vacuum pump version.

Key fitment checkpoints include the 56mm inside mounting legs, 75mm mount leg thickness, 172mm mount centres B, 163mm mount centre to centre, and 8mm adjusting hole and pivot hole diameters. Those measurements matter as much as the Bosch part number when confirming replacement suitability.

Application and Buying Notes

Before ordering, compare the Bosch part number 0124615019 with the number on the alternator being replaced. The mounting style on this unit is pad mount with direct fastening, and the supplied dimensions include 56mm inside mounting legs, 75mm mount leg thickness, 172mm mount centres B, and 163mm mount centre to centre.

The pulley details are also important. This alternator has a 6 groove pulley, a 50mm pulley outside diameter, and is listed with a free-wheel belt pulley. The product also notes recommended additional repairs as V-Belt/V-Ribbed Belt, which is worth checking if the belt condition is unknown or the belt system has wear.

Electrical specification should be matched carefully as well. This is a 12V alternator with a 150A power rating and internal regulator, so it needs to suit the vehicle’s charging setup and harness arrangement. The unit is listed as excluding vacuum pump, which is a key separator when comparing replacement alternators.

Because alternators are often swapped during repairs, it is sensible to inspect the mounting points, hole diameters, and pulley alignment before fitting. The adjusting hole diameter and pivot hole diameter are both 8mm, so those measurements should be checked against the vehicle or the removed unit rather than assumed from appearance alone.

This is a new Bosch alternator manufactured in Spain and covered by a one year warranty. Even so, the correct replacement depends on matching the part number, mount style, pulley layout, voltage, and whether the original application used an alternator without a vacuum pump.

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 0124615019 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.

Bosch Alternator 12V 150A. Part number 0124615019 should be checked first. Listed voltage is 12. Listed output rating is 150. These details form the core reference points used by parts interpreters when confirming the correct replacement.

Mount style is Pad. Regulator type is Internal. Pulley configuration is 6 Groove. Those physical and electrical details should line up with the original unit before the replacement is approved for fitment.

For part number 0124615019, 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 150 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Where no verified application list is available, the part number, mounting details, connector style, and published specifications should be used as the primary selection criteria.

In the absence of a verified fitment list, the safest approach is to compare the removed unit directly with the listed product details. That includes checking the housing style, pulley layout, regulator arrangement, and any visible identification numbers before supply is approved.

Compatibility note: Confirm compatibility by matching part number 0124615019, the Bosch brand, 12V 150A output, pad mount with direct fastening, 6 groove free-wheel pulley, and the listed mounting measurements against the removed unit or vehicle application details before purchase.
