Auxilary Belt Running Off Pulley's Slightly 1.9td

[shaunlfc1]

Hi all,

 

I have a 98 Mk2 1.9TD (with aircon) Xantia and i've noticed again the auxilary belt (the one that drives the alternator) seems to have jumped a tooth again towards the engine. So as you look at it the right hand edge/tooth of the belt is sitting over the edge of the pulleys and this edge of the belt is slightly fraid.

 

When the engine is running the belt seems to be running true and I've looked for signs of any of the pulley's it runs on are unbalanced of moving around which might have caused the belt to jump over.

 

Now the story of this belt starts shortly after we brought the car just over a year ago, at the time of buying it I didnt notice the belt but when I did the first oil change about a week later I noticed the belt was the way it is now jumped over to the right. Once again I inspected it and the trueness of the belt and all seemed fine. So I left it. About 3 months later it was put in a Citroen specialist garage for a new radiator and coolant flush and I asked the garage to take the belt off and reseat it, and check for any problems.

 

They did the job, and mentioned that they didnt find any issues with the belt or any of pulleys but did say that this is quite common on this engine and its nothing really to worry about.

 

Thing is now I was changing the light bulbs yesterday in the headlights and noticed the belt had gone back to its "more preferred" position of one tooth over to the right as described above. But this time the belt if slightly fraying and I think perhaps there is a problem.

 

The fact this belt is very important I want it sorted.

 

So has anyone had this issue and what is the cure, my first suspicion is the belt on there is the wrong belt as it does look as if its the wrong width, but the car has lots of good service history and although mistakes happen I doubt this could happen!

 

Thanks for all your help,

 

Many thanks....

I think the length of this belt on the later XU engines makes it problematic, I've had to replace the belt twice in 50,000 miles.

 

Both times the tensioner and the pulleys have had to be replaced. Mine is the 2.1TD in a 406 but the long belt run for this and the 1.9TD are similar, in the Xantia there is no power steering or vacuum pump as that comes off the main hydraulic pump.

 

If the belt frays and breaks it can get under the cam belt at the crank pulley end with disastrous consequences.

 

I would suspect that the tensioner (and possible the pulleys too) is tired. I'd replace the tensioner and the belt........ and the pulleys too if need be.

 

If the fraying gets any worse you'll hear it when the engine is running as the loose end whips about. This was how I noticed mine was on the way out last time......
