Application and Buying Notes

Before ordering, match the part number 1986A01264 and confirm the alternator arrangement on the vehicle. The key application detail here is that this unit is listed as an alternator type excl. vacuum pump, so the existing setup must be checked carefully rather than relying on appearance alone.

The 12V system voltage and 80A power rating should be compared with the original unit fitted to the vehicle. If the current alternator differs in output or configuration, the correct replacement may be different even within the same model family.

Fitment references are provided for Mercedes-Benz applications including GL-Class, M-Class, R-Class and S-Class. Because the application list is broad, the safest buying method is to confirm the part number, alternator type, mounting style and belt arrangement against the vehicle already fitted with the 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 1986A01264 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.
