auxilliary belt problem

[casperdog2]

I have a 97 xantia with air con, the hyd pump seems to be out of line, and as a result my belt only lasts a couple of thousand miles, my question is could it have the wrong sprocket on, also is there a way to ajust the pump, as I say its only 1/8 out but its enough to cut one ribs worth of belt,there is the number 2.02 on the top of the pump and I was wondering if this meant when it was made

You dont mention the engine type in your Xantia ?

It is possible the pump has been replaced some time during the life of your Xantia. As there are several variants of the pump which includes different offsets in the mounting base, chances are you simply have the wrong pump fitted.

Unfortunately the pumps dont have any terminal identifications as part no stamped on the pump body
You will have to get a correct pump for immediate in-situ comparison to identify your pump.

You must inform your exact engine type, as this together with a/c or not decides the pump variant.

PS : make sure the pumpbody is not cracked in the mounting base - and any bolts are correctly fitted and tight.

Usually, the reason for belts running out of line and having a short life is a problem with the tensioner(s). Rarely is anything being driven out of line, particularly the hydraulic pump or alternator as there is no lateral adjustment on them.

As Anders says, to know the exact model will help in giving some more specific advice. Once we know your model, there is some very specific advice that can be given to determine the cause of this problem.

Thanks for the reply lads, I was hoping that I could change the sprocket, but its never easy is it, anyway the engine is a 1900td uxd9te. I will have to get one from somewhere, ebay or a breakers if its the wrong pump. shame as its spot on.

I had a similar problem a few years ago and it was the spring loaded bearing which had collapsed causing the problem.
