    As that is the PRV engine, are any Volvo parts suitable?

    No I haven't checked any Volvo parts yet. Which model and engine capacity?
    I know these Renault models use the same engine more or less :
    Espace III (JEO_)
    Laguna Grandtour (K56_)
    Safrane I (B54_)

    I was thinking the B280 series motors, late eighties, early nineties.

    All three tensioners/idlers look quite different to the aircon PRVs fitted to XM and 605.

    Have you checked the website of Mister-Auto? Probably not much there (but worth a look), your other source is German Fleabay, where quite often searching by part number will bring up old stock.

    Thanks for that. I'll check them out.
    Even just the bearings will do the job. I've extracted one of them but don't know what type it's called to search for them by name. Looks like this one in the pic bellow.
    The pulley is pressed onto the outter and the smaller post is pressed into the bracket.

    I have a complete used set - or are you looking for new?
    Where are you located?
    I'm in Melbourne.

    Is that right?

    Easy one first.
    looks like 7mm DIAMETER from your photo, (we can't see the zero mark, a better shot would have one edge over the 10mm mark, 'cause the end of the ruler may be damaged...)or use an open end spanner as a caliper, sight the scale on the rule to give the difference.
    And of course to really identify it you need to specify the pitch of the thread; using a rule the best way is to count the number of thread crests over a distance and divide by that distance, or measure the distance that ten crests spans (in mm) and divide by 10.
    For bearings I would suggest your local bearing supply shop, since you have one apart they should be able to identify it by the numbers stamped on it. Or run their vernier over it for the measurements And if you have one apart you should be able to get the others apart too....?
    And they will probably know the local bolt suppliers.

    Try BSC or CBC Bearings locally take in the bearings and show them

    Or I get my bits from UK, sometimes I need to use a fright forwarder though, takes about 7 days now with Christmas rush over

    Fleabay liquidators "youwantwehave" carry at least that tensioner; they don't post to Oz but that can be easily circumvented.

    I have been through the same thing
    Scored two of the pulleys off ebay at good prices from England.
    I ordered a third but I got the wrong one!
    It was for a car without aircon. (different type of motor).
    I have spotted the right one but they want $300 +
    If you keep searching you should come across them, but I have noticed the UK postage going up!

    I showed the complete pulley to one of the bearing company but the said they weren't available.
    I would be interested if you can track down the bearings on their own.
    Was it easy to press out?

    cheers

    Mike

    I think that first one maybe wrong
    One of them should have a grooved pulley like the one in the attached photo

    I ended up getting the 3 pulleys locally second hand but in decent condition. Would love to have all new ones but really expensive at over 100 each from Europe.
    As for the pulley with grooves, I saw it listed for the Z7X engine but definitely it's not on mine.
    Pressing out the bearings was an adventure! Used a smaller puller to extract the pulley from the bearing then a hydraulic press to push the bearing out of the bracket for the one bellow in the pic.

    As for the other one in the pic bellow.
    Deflection/Guide Pulleys-imageuploadedbyaussiefrogs1389846506.517552.jpg

    I noticed the retaining nut had an Allen key slot, so put in the vice and proceeded to unscrew it, only to have it shatter after I used heaps of force undoing it. Upon closer inspection, found that it was actually left hand thread!

    The extremely rare 7mm (1.0 thread) exhaust manifold studs I found at "Champion Parts" on Arden Street, Nth Melbourne. They have compatible bolts
    That I used.

    Haven't been able to find a match for the bearings as yet.
