Description

Alternator Pulley for the 2.5L 300TDi turbo diesel, part of the alternator drive in the engine’s charging system.

The pulley mounts on the alternator shaft and is turned by the poly-V (multi-rib) auxiliary drive belt, transferring crankshaft rotation to the alternator to generate charge. This is the 61mm poly-V type.

The companion drive components are the auxiliary belt and tensioner; a worn or contaminated pulley groove can cause belt slip and reduced charging output.
