TT6 Auxiliary Tensioner Pulley Replacement

Recommended Posts

This topic is just to share some information about the tensioner pulley found on the TT6 models with the damper setup. I was looking to replace the pulley but not the tensioner itself as it's still fine. However with the steel OEM model pulleys you can just swap out the bearing and it's good to go. This pulley does not fit with the TT6 damper as it either hits the tensioner itself or the damper in front of it. Toyota does not sell the pulley separately from the tensioner and the TT6 model tensioner is fairly expensive. 

There is an alternative though! The pulley from most Mercedes petrol models from '98 to '08 will fit fine and it looks almost identical to the OEM unit. It also has the same diameter and width, I run a small 17mm crush washer behind the pulley to center it just a tiny bit better on the belt but the OEM unit is also not perfectly centered so you could choose to not do this.

The OE Mercedes part number for the tensioner is 112 200 00 70, but you can also easily find just the pulley on either Ebay or maybe at an automotive parts store. It comes on the following models:

C240 (2001-2005) | C280 (1998-2000) | C320 (2001-2005) | C43 AMG (1998-2000) | C55 AMG (2005-2006) | CL500 (2000-2006) | CL55 AMG (2001-2006) | CL500 (2000-2006) | CL55 AMG (2001-2006) | CLK320 (1998-2005) | CLK430 (1999-2003) | CLK500 (2003-2006) | CLK55 AMG (2001-2006) | CLS500 (2006) | CLK55 AMG (2001-2006) | CLS500 (2006) | CLS55 AMG (2006) | E320 (1998-2004) (2005 - 3.2 V6) | E430 (1998-2002) | E500 (2003-2006) | E55 AMG (1999-2006) | G500 (2002-2008) | G55 AMG (2003-2011) | ML320 (1998-2003) | ML350 (2003-2005) | ML430 (1999-2001) | ML500 (2002-2007) | ML55 AMG (2000-2003) | R500 (2006-2007) | S350 (2006) | S430 (2000-2006) | S500 (2000-2006) | S55 AMG (2001-2006) | SL500 (1999-2006) | SL55 AMG (2003-2008)
