Arrgh! Cambelt too tight!

[BUSHWHACKER]

Don't see why - loads of cars have a 'set the initial tension and forget type thing'

My corsa has an arrow marker that you have to twist the water pump pulley around to set the tension with. Once set that's it.

Maybe old diesels are different? Not exactly smooth running are they.

It would just be an idler.

An idler would not set any tension on the belt. If you have a pulley wheel that is spring loaded it would place a tension on the belt. Therefore it would be a tensioner. Whether it would be 'self adjusting' or not is what sparked my initial post.

My corsa is petrol....

It seems like wishbone here is the only one who has any idea on how the 2.4 tensioner works. Take note of what he says because he is.........

:nods:

The 2.4 isn't dynamically tensioned, its set at initial fitting, and thats it.

Ah, hence the confusion. I only have experience of the 3.0, hence my comments. Didn't know the 2.4 was different in terms of its tensioner.

Christ on a bike Nev, you took your time!

I had a hard time keeping this thread going until you woke up.

Thanks Nev - I thought I was losing my memory for a bit there

I only dismantle them and not put them together so i thought the 3.0 and 2.4 were the same

Hey, I've been working and don't get a much time for forums now. Getting up at 4.30 am, home at 5.00 pm and driving about 750 Ks a week.

The 2.4 has a spring, but all it does is set the initial tension. Once that is done, the centre bolt is tightened and that's where the tensioner stays.

i need to pay more attention to how i dismantle things i think...

[hellmett]

re

So my initial diagnosis was correct?

I have 'over tightened' the belt by pushing the tensioner wheel to forcefully against the belt and locking the bolt?

To remedy, loosen the bolt and let the wheel move slightly away from the belt, then retighten the bolt?

Still involves stripping the bugger down, groan!

Well there you go, I thought it floated. We live and learn.

I'm trying to think back to when I did my 2.4 belt (only the once mind) I could swear blind it didn't tighten up!

Isn't it wierd how when one expects something to happen, even when it apparently doesn't, one still can't be sure it didn't!
