Application and Buying Notes

Before ordering, compare the part number 1986A01047, the 12V rating and the 150A charge current with the alternator currently fitted to the vehicle. The alternator is specified as excl. vacuum pump, so that detail needs to match the application on the vehicle rather than relying on appearance alone.

Fitment references include MERCEDES-BENZ C-CLASS applications, with sample years shown from 2013 through 2018. Those references are useful for narrowing the application, but the safest approach is still to confirm the exact fit using the part number, alternator type and vehicle application details before purchase.

When replacing an alternator, it is sensible to inspect the belt condition, tensioning components and associated charging system parts. The listed 12 month warranty applies to the part, but correct identification and matching specifications remain the buyer’s responsibility prior to fitting.

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 1986A01047 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.
