    yes had the same thing on mine a few months back. The belt let go but when I replaced it with new ones, they all kept riding forward off the pulleys and shredding. Finally worked out that the original cause of the first belt coming to grief was the tensioner being worn and causing misallignment...new one fitted and no more probs................except a slight vertical wobble on the tensioner pulley at idle of about 2mm...that i didnt recall being the case previously?

    Thanks guys for your input,

    the reason i didn't do a search, for squealing fan belts, is because it doesn;t, or didn't squeal.
    Now that i look at it, the wearing of the back of the belt because of wear on the tensioner, must be the precursor to squealing, or in my case total belt failure.

    McR, I was going to put a post on when the belts went , just to let others know what could happen, but had a rethink and changed my mind. Different wear pattersn cause different probs, yours went backwards ands Eddo's went forward, maybe the lessor of two evils.

    On my a/c cmpressor I had to pull take the pulley of, then the clutch and the 'ferrite' magnet thingy, i only had an inch of wire poking out, resoldered and back on, the only hard bit was retensioning the idler puller, another three handed job.
    Have about 3 hours befoe the parcel turns up and i can replace the tensioner.
    In one respect i am glad I noticed it here and not when on one of my trips.

    Another one to keep in the memory bank,
    maybe another one for the mods to think of, something like ' Wear options and the symptoms'

    thanks again to all.

    John, the tensioner is a Dayco, should be able to source through the local parts supplier cheaper than the Landy importers.

    Just swapped out a 300Tdi one last week (which looks very similar to yours) as it had started to seize on the nylon bush yet there was heaps of tension left in the spring.

    BTW, I've always used Gates belts and have had to replace them far too frequently, cracking in less than twelve months and frequent squeaking, both the poly vee on the Landy and the vee belts on the Patrol.
    Gone to Dayco across the board and so far so good.

    squealling belt

    also remember the waterpump. The water pump can leak and cause the bearing to stop and with that the belt dont go. I would spin the water pump while I had the belt removed. It did it for me

    Thanks Guys,
    Yes Rick it is a dayco and arrived yesterday, from one of the recommended suppliers. I have dealt with them in the past there prices are fine.

    Its in an now that I have taken the old one off I see the thing is out of alignment, the rubber bushings are worn down, sort of tilting it at an angle henceforth the symptoms, of shredding the belt.
    I will re-interate, the belt was not squealing nor making any sort of noise it was as quiet as a mouse.

    The new tensioner is solid, doesn't bump up and down like the old one.
    Eddo, that movement you describe could be the bearing, the pulley bearing in the new one I got has some side to side play in it, weird, a new bearing , more than the old bearing.
    Will ring the suppliers today to see if it is normal.


    all is good,

    john
