    Post How to: Change Auxiliary Pulley, Tensioner, Belt and Shield

    How to fit Upgraded Lower Pulley, Tensioner, Belt and Shield


    If your X-Type Diesel is rattling and clattering at tickover and then gets worse when you put the aircon on it is most likely to be the lower pulley or tensioner.

    Having read everyone else’s posts on this I have tried to make the job as easy as possible as some steps were unclear and to make it easy for FMs to have a go at by taking lots of photos and adding descriptions. You don’t have to do it this way but this took just 2.5 hours to do inc. tea breaks. I used the tensioner tool for this job everything else most people will have.


    I used:
    7mm socket
    10mm socket
    13mm socket
    15mm socket
    Extension bars
    Breaker bar
    Torque wrench
    Trolley jack and Axle Stands
    Torch (it gets a bit dark trying to route the belt)
    8mm Allen Key to remove tensioner from alternator mounting bracket

    Tensioner Tool
    Auxillary Fan Belt Tensioner Tool Duratorq Ford Mondeo Laser 5208 | eBay


    Genuine Jaguar full upgrade kit
    Which includes:
    Upgraded pulley
    3 pulley fixing bolts
    Tensioner
    Drive Belt
    Deeper pulley shield
    Don’t use cheap and nasty get a genuine kit
    GENUINE JAGUAR X TYPE MODIFIED AUXILLARY TENSIONER & PULLEY KIT | eBay

    I have taken close up pictures of the part numbers so you can source from a different supplier if you wish.

    Start by jacking car and use axle stands, remove offside wheel and undo fixings holding pulley shield, disconnect battery cable as you will be moving alternator later.


































































    Torque settings are:

    Lower Pulley 100Nm then a further 90 degrees

    Alternator Nuts and bolts 47Nm

    All Tensioner Bolts 47Nm

    Thanks to all whose info I used to do this job

    Hope this helps
    Cheers
    Steve

    Thank you fantastic guide, i did mine yesterday, not as quickly as you.It took me a little while to orientate myself with the alternator etc,and i made a couple of mistakes, like forgetting the lower bolt in the tensioner mounting bracket, i didnt realise until i had finished and was just doing a mental check before testing, hence had to take it all apart again because that bolt is behind the alternator, then i couldnt get the top alternator bolt back again the whole thing was back together and belt under tension i think this was just pulling the alternator out of line. Still persistence pays off and it is now done, sounds soooooo much better.

    ****** good work Sir

    Far better than any Haynes manual!!!!
    How about doing something similar for everything on the X Type??? haha

    One question though -- what is the main significance of the modified pulley?

    Andy the upgraded pulley is stronger than the standard one. The standard rubber separates and the inner and outer become detached eventually failing dramatically!
    There is much more rubber around the upgraded unit so it doesn't wobble and vibrate its about twice the weight of the standard pulley.
    some of the pattern parts around are pretty crappy as Rowtrak found out, he got a wobbly one from transitparts on ebay.

    The genuine kit is not much more than the cheapo ones, dont do the job 2 or 3 times just once is enough!

    Difference between old and upgraded pulley below



    The extra pulley way is for another belt not used on the X

    Great guide Steve. I suppose I'll have to save the pennies and do mine now. The noise is the one thing I hate about my Jag(and the missing washer jet and towing eye covers)

    Quick question Steve................. IF i have no rattles or strange noises from this end but I have noticed that the belt looks a bit "tired" couldn't I just change the belt and leave the original pulley and tensioner in situ?

    Just a thought

    Andy you could, but to do it you need to remove the tensioner to get the belt through, if you are planning to keep your X, I personally would leave the belt a while and get a new tensioner as well, I think if you are going to the trouble of getting the tensioner off to change the belt it would be daft not to put a new tensioner back on. The lower pulley is probably the easiest bit of the job which you could do at a later time, a knackered pulley can wreck the new tensioner though so if you go this route you would need to keep a close eye(ear!) on the pulley.
