Application and Buying Notes

When checking whether this alternator suits your vehicle, the most important identifiers are the Bosch part number 1986A01617, the 12V system requirement and the 110A charge current. Those details need to line up with the existing unit or the vehicle specification, because an alternator can look similar while still being different in fastening or internal design.

Corrosion resistant construction and the reduction drive are practical features, but they do not replace a proper fitment check. Confirm the application by comparing the part number, voltage, current rating and alternator type against the vehicle and the removed component before you place 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 1986A01617 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.
