Description

Alternator – A127-type 100A alternator serving the charging circuit of the 300 Tdi 2.5L turbo-diesel engine. Belt-driven from the crankshaft pulley, it supplies charging current to the battery and the vehicle electrical system.

This unit carries the smaller-diameter pulley (approximately 50mm) and runs the shorter 1580mm drive belt (companion belt ERR5911). Two pulley sizes were fitted to this engine, so confirm the pulley diameter and matching belt length before installation.
