Re: v6 timing belt tension.

You need cam locks. You can't do it without them.

These threads should give you an idea:

Alfa Romeo forum: Knocking 3.0 V6 Strip down (Dead) 56k!
Alfa Romeo forum: Another V6 rebuild ( GTA ) snapped belt

and this was my 1st attempt, nearly 3 years ago....

Alfa Romeo forum: Arrrrgh! V6 cam belt help!!!!! pics added

there's this one too, but it'll be a real trawl to find any decent, relevant info.

Re: v6 timing belt tension.

Re: v6 timing belt tension.

They're on a taper lock. They're not keyed to the cam shafts...

You need the tool to hold the cam pullies whilst you undo and tighten the bolts holding them onto the cams. If you use the camlocks for this you'll end up stripping the threads in the heads.
