Application and Buying Notes

When checking this alternator for a vehicle, start with the part number 1986A01055, then confirm the vehicle uses a 12V charging system with a 180A alternator specification. Those are the most direct identifiers in the listing and are the safest way to narrow the match.

Bosch also recommends a V-Belt/V-Ribbed Belt as an additional repair item. If the belt is worn, glazed or noisy, replacing it during alternator work can save repeat labour, but the belt itself still needs to be matched to the vehicle correctly.

The 12 Months warranty provides a clear purchase reference, but it does not replace fitment checking. Confirm the alternator type, charge current, fastening style and part number against the vehicle’s existing unit or catalogue listing before you commit to the order.

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 1986A01055 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.
