Bosch Alternator 12V 180A Incl. Vacuum Pump 1986A01050

The Bosch Alternator 12V 180A is a new OE product, supplied each, with part number 1986A01050. It is an alternator assembly rated at 180A and built for 12V systems, so it is intended for applications that match both the electrical output and the physical mounting arrangement.

This unit is listed as an alternator type incl. vacuum pump, with a 6 groove pulley, CW rotation, and a quad leg mount. Key mounting dimensions include 61mm inside mounting legs and 128mm mount centre to centre, with an M8x1.25 / 9 adjusting hole diameter.

As with any alternator replacement, the mounting style and drive arrangement matter as much as the electrical rating. This Bosch unit is supplied new, carries a one year warranty, and is described as an OE product, which makes accurate part matching especially important before ordering.

The listed application data points to selected Audi, Skoda and Volkswagen vehicles, including A3, Kodiaq, Octavia, Superb, Caddy, California and Crafter 30-50 references in the fitment information provided. Because alternator fitment can vary by engine and build details, the part number and physical measurements should be checked carefully against the existing unit.

Application and Buying Notes

Before ordering, compare the part number 1986A01050 and confirm the alternator layout on the vehicle, especially because this unit is listed as incl. vacuum pump and uses a quad leg mount. A mismatch in mounting style, pulley section, or rotation can prevent installation even when the electrical rating is close.

The most useful dimensions here are 12V, 180A, 50mm pulley outside diameter, 6 groove pulley section, 61mm inside mounting legs, and 128mm mount centre to centre. These details are the practical checks that matter when matching to the existing alternator and belt drive arrangement.

If your existing unit is not clearly marked, remove it and compare the mounting points, adjusting hole size, and pulley configuration before buying. The note recommending additional repairs on the V-Belt/V-Ribbed Belt is also worth considering if the belt shows wear, because belt condition affects alternator drive reliability.

This alternator is listed against selected Audi, Skoda and Volkswagen applications in the fitment information, but those references still need to be matched to the exact vehicle build. Engine variant, accessory layout and belt drive details can change fitment, so the part number remains the safest starting point for confirmation.

The fact that this is a new Bosch OE product gives a clear baseline for quality and specification, but it does not replace vehicle confirmation. Use the existing alternator, vehicle identification details and the fitment references together before placing the order.

For workshop or trade buyers, the one year warranty and each unit measure make this a straightforward replacement part, provided the application has been checked properly. Where the vehicle uses a vacuum pump integrated with the alternator, the overall unit design must match exactly, not just the amperage rating.

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 1986A01050 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 180A. Part number 1986A01050 should be checked first. Listed voltage is 12. Listed output rating is 180. These details form the core reference points used by parts interpreters when confirming the correct replacement.

Mount style is Quad Leg. 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 1986A01050, 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.

Compatibility note: Confirm fitment by checking part number 1986A01050, the 12V 180A rating, the incl. vacuum pump design, and the mounting and pulley details against the vehicle before ordering. If the existing alternator differs in rotation, mounting style, or pulley section, do not assume it will interchange.
