This Bosch alternator is a 24V, 110A unit identified by part number 1986A01033. It is listed as a new alternator, made in Spain, with an internal regulator and a twin leg alternator mount, so the electrical and mounting details need to match the vehicle application before ordering.

The pulley setup is an 8 groove design with a pulley outside diameter of 62mm and clockwise rotation. Mounting measurements provided include 101mm inside mounting legs, 198mm mount centre to centre, 13mm pivot hole diameter and 11mm adjusting hole diameter, which are the key checks for a direct replacement comparison.

This alternator is listed as excluding a vacuum pump and is intended for Bosch applications. The unit is supplied with a 12 month warranty and is described as using high quality raw materials, non-recycled copper and premium quality bearings for endurance and reliability.

Application and Buying Notes

When comparing this alternator to the unit already fitted to the vehicle, the most important checks are 24V system voltage, 110A output, twin leg mounting and the 8 groove pulley. The part number 1986A01033 should be matched first, then the mounting dimensions of 101mm inside mounting legs and 198mm centre to centre can be checked against the original unit.

The alternator is listed as excluding a vacuum pump, so that detail matters on vehicles where the original assembly includes one. If the vehicle uses a different alternator layout, the mounting style, pulley section and rotation must all line up with the existing unit before the part is considered suitable.

This unit is described as new and fitted with an internal regulator, which is relevant where the vehicle relies on the alternator’s own regulation rather than an external regulator arrangement. The supplied 12 month warranty gives a clear reference point, but it does not replace the need to confirm the application and physical fit before purchase.

Recommended additional repairs include the V-belt or V-ribbed belt. That is worth checking whenever the alternator is being replaced, because belt condition and belt match affect installation and charging performance. If the belt is worn, glazed or incorrect for the pulley section, it is sensible to address that at the same time as the alternator.

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 1986A01033 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.
