Bosch Alternator 12V 150A Part No. 1986A01168

This Bosch alternator is a 12V, 150A unit with part number 1986A01168, supplied as an alternator for rotating electrical applications. It uses an internal regulator, a 6 groove pulley, and direct fastening, so matching the physical layout and electrical requirements is important before ordering.

The mounting details are specific: inside mounting legs are 56mm, mount leg thickness is 75mm, mount centres C to C are 163mm, and mount centres B are 172mm. The alternator mount is pad style, with 8mm adjusting hole diameter and 8mm pivot hole diameter, which makes accurate comparison against the existing unit essential.

This unit is listed as alternator type excl. vacuum pump and is manufactured in Spain. It also carries a 12 months warranty and a charge current of 150A, so it is intended for applications that call for this exact output and configuration rather than a general universal replacement.

Application and Buying Notes

Before ordering, compare the Bosch part number 1986A01168 against the removed alternator and check the mounting layout carefully. The important physical checks here are the 56mm inside mounting legs, 75mm mount leg thickness, 163mm mount centres C to C, 172mm mount centres B, and the 8mm pivot and adjusting holes.

Electrical and drive details also need to match. This unit is a 12V alternator rated at 150A with an internal regulator and a 6 groove pulley measuring 50mm outside diameter. If the vehicle uses a different pulley section, regulator arrangement, or mount style, the part should not be assumed to fit.

The alternator is listed as excl. vacuum pump, so the presence or absence of a vacuum pump arrangement is a key check. It is also sensible to inspect the belt condition and related components at the same time, as the recommended additional repair is a V-Belt or V-Ribbed Belt.

For a clean install, compare the existing bracket and belt alignment before purchase. Direct fastening and pad mounting are specific to this unit, and the dimensions given above should be treated as the deciding checks when confirming suitability for the vehicle.

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 1986A01168 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.
