Audi A6: what is proceedure for changing cam chain tensioner

This answer was rated:

what is proceedure for changing cam chain tensioner pads?

I am going back together with it and the guide I have shows 16 cam chain rollers are supposed to be between the timing marks. Mine was set at 15. Which is correct and if mine is incorrect, which cam should I rotate to get the correct distance?

Ok, are you able to get the chain tight and have the arrows line up with the squares?

i stopped when I didn't have the correct # XXXXX rollers (pins) between my marks. I couldn't see the small marks on the cam before so I made my own marks. now that I see these. there are 16 pins between. I will install caps etc and see how it tensions up.

Ok, as long as the marks line up like in the picture you are going to be ok.

it tensioned up nice. but turned as tightened cam bearing caps. is there a safe position to put crank in so i can turn cams back to alignment?

Yes, put the crank at 15 degrees past top dead center. Then you can move the cams as much as you want to.

ok, past would be clockwise correct?


also - i need to replace 2 of the cap fasteners - is there a specific grade spec for these? I'm thinking not, with only 7 lb torque, but want to be sure.

Yes past clockwise...

As for the cap its only 7 foot pounds.

I am ready to install timing belt. Is the correct cam & crank position to have cams both with alignment marks and crank at TDC mark?

Yes, for sure.
