[V6-12v] Timing Belt Tensioner Torque Setting

[James Whitehouse]

Hi All,

 

Put the timing belt back in last night. Some confusion over the torque
setting for the timing belt. My Audi workshop manual gives two torques:

 

8 mm bolt: 22 Nm

10 mm bolt: 43 Nm

 

The tensioner on ours had two 8 mm holes one for pulling the tension, and
one bolt, which we tightened to the 8mm setting (22 Nm). There was no 10 mm
bolt on this car. However, 22 Nm seems offhand to be a little slack to me
for such a critical bolt. Can anyone confirm the tension of the timing bolt
for the 8mm when doing the belt timing from another manual like a Bentley or
similar?

 

What are Audi on about anyway with their 8mm / 10mm stuff? Is this if you
get a tensioning roller with a 10mm bolt instead of an 8mm? I’m confused and
it’s not good to be confused about a timing belt torque setting!

 

Cheers,

James
