Application and Buying Notes

Before ordering, check the part number 1986A01041 against the alternator currently fitted to the vehicle, as that is the most reliable way to confirm application. Also compare the mounting style and dimensions: twin leg mount, 60mm inside mounting legs, 130mm centre-to-centre mount spacing, and an M8x1.25 / 8 pivot hole diameter.

The electrical side must also match. This alternator is 12V with a 150A charge current and an internal regulator, so the existing charging system should be checked for the same voltage, regulator arrangement, and alternator type. It is listed as excl. vacuum pump, which matters where the original unit includes a different construction.

Pulley details should be verified before purchase. The unit has a 52mm outside pulley diameter and a 5 groove pulley section, so belt alignment and belt type need to suit the vehicle’s setup. If the belt shows wear, the recommended additional repair is a V-Belt or V-Ribbed Belt, which is worth considering at the same time as the alternator.

Because fitment data is not provided here, the safest approach is to confirm the original alternator label, mounting points, pulley groove count, and electrical specification against this Bosch unit. That is the practical way to avoid a mismatch on installation day and to make sure the replacement follows the same configuration as the original part.

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 1986A01041 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.
