A stronger replacement for the OEM part, this German engineered Aluminum Pulley has a replaceable bearing for the serpentine belt tensioner and is crafted expressly for the Mercedes-Benz M113 engine family.
Unlike the original OEM Mercedes-Benz plastic or sheet metal pulleys the all Aluminum Tensioner Pulley is precision machined from strong aerospace aluminum.
It features a serviceable ball bearing which is retained by a snap ring and can be replaced if ever needed.
This pulley is a very easy install onto the existing belt tensioner using the existing OEM Mercedes-Benz hardware, however a Torx socket bit (tamper proof) is needed for the installation.
