    AND IN TURN WRECKED ENGINE ,Hi, don't know if yous remember that we broke down in France about 3 weeks ago 1 hour from Calais. Insurance got us home in 4 days and mh a few days later. We had a new cambelt fitted before we left, 240 miles later it all broke,we think it was not fitted correctly. The garage have come up with several reasons the latest being that the air-conditioning pump seized wrecking the drive belt!
    Has this happened to anyone else? I have images of immediate damage it looks very out of line ( flywheel, idlers, etc) and what I think may be an important bolt \ stud snapped at nasty angle .
    Please if you have same engine (Ducato 2.8jtd) put an image of left hand side of engine straight down to the floor showing alignment of auxiliary belt, cheers, will try to put image on off the phone,
    Many thanks, jaks and andy

    Air con compressor is driven by auxiliary belt not the cambelt. Try as I might I cannot come up with a reason for a failed AC compressor to derail the cambelt. A seized AC compressor would first of all only cause a problem with the AC turned on (there is an electromagnetic clutch on the AC pulley) and even if it seized all it would do is cause the AC drive belt to slip which would squeal horribly and let you know there was a problem. There is a thick plastic shield between the aux belts and cam belt so derailing the aux belt would not be likely to affect the cambelt.

    I can't see the cam belt driving the air conditioning pump. It will have a separate belt of a different type and the engine shouldn't be wrecked if the pump seized.

    I can only suggest finding an independent automotive engineer to look at it as this is going to be expensive.

    My suspicion is the garage did something wrong in fitting the cambelt but hard to be certain. For example it is usually good practice (depends on the engine) to change the idler at the same time but if you didn't ask them to do this is it their fault? They should have suggested it if it should have been done but there is no obligation for them to do so.

    I could be wrong but isn't the A.C pump on the auxiliary drive belt rather than the cam belt :cautious:

    EDIT spent too long thinking whilst others were pressing submit :LOL:

    Jaks & Andy,

    Really sorry to hear of your bad luck. When we suffered the same bad luck near Toulouse, what should have been a new engine turned out to be either a scam engine from a donor vehicle, or a recon using worn parts. The only reason all this came to light in the end, was because whoever fitted the new camshaft belt ,fitted the two part casing the wrong way round. This caused the auxiliary drive belt to fray, snap off and enter the casing, dislodging the cambelt, which in turn totally ruined the engine. Had it not been for that fitter's failure, we might have never know about the scam.

    Once the insurance assessor got involved things started to come to light, and the original repairer tried desperately to cover their tracks. My refusal to let the MH be transported back to their base in Sheffield was instrumental in them being sussed out and eventually taken to court by Equity Red Star, for around £10,000 of costs between the insurers and us.

    If yours isn't an insurance repair, get an independent engineer's report done, before the garage start trying to alter things to cover their tracks. If it is an insurance repair, make your suspicions known to the insurers asap.

    The very best of luck to you both. (y) We've been there, done it,and felt the pain and frustrations. :(

    Jock (& Rita).

    Hi all thanks for replays, yes the ac is driven by its own aux belt and this is only the latest reason for problem with the cambelt becoming loose ( not snapped) that the garage have come up with! Have put images on what is the bottom pulley for? And can you see it out of line and true? Cheers all Andy& jaks

    From your photos, those tensioners and pulleys don't look aligned to me either. :(

    When you say the engine is wrecked, what exactly has happened? What are the garage telling you has happened? Not the reason why, but what is broken or bent? If the garage changed the cam belt they would have had to remove the auxiliary drive belt and this seems to be the problem. At a guess, from the pictures it is a failed idler, but hard to be certain. From memory the bottom pulley is the water pump but don't quote me!

    When the AC compressor seized on my Shogun it squeeled like mad and smoked as well (that was the belt slipping), when I realised what it was I turned off the air con and all was OK, likewise when we bought our motorhome the AC pump was seized and had no belt on at all.

    Those pulleys in your picture are all for the auxiliary drive belt which would drive the compressor. Is the garage saying that the aux drive belt coming off, interfered with the tension of the cam belt ? It's possible when the aux belt snapped, it could wrap around the crankshaft timing pulley and cause the timing belt to loosen or jump. There does look to be some damage to the cam belt guard in the picture. My instinct says the garage have messed up somewhere

    We could go on guessing all night but I will just say I hope that you get it sorted and back on the road without too much pain.

    Thanks Bill. (y)

    Unfortunately, it was an experience not to be forgotten, and had it not been an insurance protected incident, it could very well have meant the end of out MH'ing days. :(

    Cheers,

    Jock.
