Whenever you change the belt (now recommended in UK at 36K mile intervals, so about 50K kilometres I guess) you should replace both the fixed and the adjustable tensioners. The early sprung tensioner had a cogged drive that wasn't as durable as it should have been and wore. The design was upgraded and its doubtful if any of the old stock are about now. Some people claim that the new more durable tensioners wear the belt more, of course.......

As someone already said, I'm not talking about the tensioner but the support were you tighten the tensioner.
If you look at the image I post on Eper, it says that the tensioner support was modified because of belt wear issues...

Hi mate, salutes from Portugal also☺
Well you can see the modification stated in eper, I found this because I've been having issues with the aftermarket tensioners.

well, searching Eper, the Support you are asking about seams to only be available for 2.0 TS engines. A bit relieved on my side, as my alfas are running only on 1.6 and 1.8 ts engines.

Aha! Are there 2 part numbers for #12, the captive tensioner bolt? That might explain your wobbly tensioner in your other thread - if the replacement support uses a heavier bolt, and your cambelt kit and new tensioner were designed to fit that.

If not, Alfa seem to constantly change things during production, just to make life more exciting for us.

Well, i'm confused because there aren't two part numbers for the captive tensioner bolt:ermm:

But why on earth no one ever had this issue?
I've never saw this issue stated in any place before, nor talking about this new upgrade support, only about the new tensioner....

maybe people had the issue, but never got to know the official solution... specially because it appears to be a specific 2.0L engine problem.

anyway, regarding timing belt change, got myself reading the latest 147 owners manual, maintenance section, and timing belt should be changed each 60 000 km or 5 years, whichever comes first, or after 4 years running in rough conditions.
