Bosch Alternator 12V 180A 1986A01052

The Bosch alternator listed here is a new 12V unit with a 180A charge current, part number 1986A01052. It is a pad mount alternator with direct fastening and is listed as an alternator type excl. vacuum pump, so the mounting style and accessory arrangement need to match the vehicle application before purchase.

Key dimensions that matter for checking compatibility are the 36mm mount centres A, 52mm mount centres B, 10.5mm pivot hole diameter, 10.5mm adjusting hole diameter, and 17mm shaft diameter. The pulley section is not applicable, and the note states pulley to suit PLX099, so the pulley requirement should be confirmed against the vehicle setup.

This unit is supplied as a Bosch alternator, new, and carries a 12 month warranty. It is listed with CCW rotation and a recommended additional repair of the V-Belt/V-Ribbed Belt, which is worth considering when replacing charging components as part of a broader repair plan.

Application and Buying Notes

When comparing this alternator to the vehicle’s original unit, the most important checks are part number 1986A01052, 12V system voltage, 180A output, and the pad mount with direct fastening. The listed dimensions also matter: 36mm mount centres A, 52mm mount centres B, 10.5mm pivot hole diameter, 10.5mm adjusting hole diameter, and a 17mm shaft diameter.

The alternator is identified as CCW rotation and excl. vacuum pump, which means it should only be considered where those details match the existing charging assembly. A mismatch in rotation, mount style, or vacuum pump arrangement can prevent proper installation even when the vehicle appears similar on paper.

The pulley note is specific: pulley to suit PLX099. That means the pulley setup should be checked carefully against the vehicle’s existing parts and belt arrangement before purchase. The recommendation for additional repair of the V-Belt/V-Ribbed Belt is also relevant if the belt shows wear, glazing, cracking, or age-related deterioration during alternator replacement.

For the cleanest result, compare the physical alternator against the old unit where possible, including mount centres, hole diameters, shaft diameter, and rotation direction. These measurements provide a more reliable confirmation than model name alone, particularly on vehicles with more than one charging system variation.

Although the fitment references point to Volvo S60, V60, XC60 and XC70 applications, the safest approach is still to confirm the vehicle’s exact configuration and the alternator details before ordering. The listed warranty is 12 months, and the unit is supplied new, but correct identification remains the key step.

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 1986A01052 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.
