hi all i have finally got myself a nice v reg weekend version to play with having sold my lancia dedra 2000 turbo. i have sorted most problems on it but i have still got a noise from the power steering belt area to sort. i thought that it was just a noise i would have to get used to (my first diesel car) but after taking the belt off and starting the engine i couldn't believe the difference! the noise i have is like a cloncking and thudding on tickover and up to about 1500 revs, it is definatly not to do with the cam belt as checked earlier. incedentally i changed the timing belt and tensioners as one of the first jobs a few weeks ago . the air conditioning is not functioning due to a broken pipe from the compressor ( my next job ), could this make the noise if its 'running dry'? i have read on this site about problems with the automatic tensioning system and the crankshaft pulley itself. is either or both worth changing, bearing in mind they are quite expensive, but then as the guy who had his pulley fall apart and bugger the timing belt says any help and advice will be taken on board. p.s. this really is a great source of advice, i used it many times before getting the car i wanted , as soon as its sorted how i need it to be mr angeltuning is gonna up the power a bit

mine 105JTD also have a rattling sound when the v-belt get 'loose' and self tensioner vibrates badly. it only happen when rpm below 800. during idling at 850rpm, i can see the v-belt self tensinor vibrate up n down more than 10-15mm. when the engine load is higher, the tensioner vibrates even more and causing the belt loose n tight situation.

there is when rattling noise coming out. change a v-belt but not the problem...most likely need to change the tensioner to give it a try.

pls check your tension if it vibrate badly or not.

we can share and solve the problem.

iv'e spoken to my local fiat dealer and ordered a new crankshaft pulley. he says they do give prioblems in the rubber damping system that is inside them. they have to replace plenty, particularly on the punto jtd. it should arrive tomorrow, if so i will fit it this weekend and hope that it cures the noise. i will post my results as soon as i have any. my automatic tensioner does vibrate and move whilst on tick-over, it seems to be that that is what it's job is, to keep a good tension at all times. the vibration comes through from the pulley not damping the vibrations enough. thats my theory anyway!:idea: i took my tensioner apart last weekend to see how it works, quite a simple thing really but VERY expensive to replace. , like the pulley incedentally, when i took my tensioner apart the pivot point was pretty well corroded and needed stripping down and cleaning before reassembling with grease to prevent it siezing in the future. whilst i was at it the bearing was stripped down, cleaned and re-greased:yum: fingers crossed

hi tazztham, i got new pulley toady so have fitted it tonight. success! my car is now as quiet as any diesel i have heard i would certainly recommend fitting a new pulley if yours is still the original, from what i can gather the rubber insert gives trouble. the new one has been slightly redesiged so that in itself points towards a known problem just make sure your tensioner is ok before going ahead the bushes on the spring ends on mine were worn but just in one small area so i was able to turn them round so a good part of bush was in the area where the most stress was going to be it is only a temporary solution but it allowed me to eliminate the tensioner from my suspisions whilst you are there make sure the pivot point on the tensioner is free moving, mine was almost siezed so needed stripping down and re-greasing, make sure to use a grease that is designed to be used on rubber such as red rubber grease for brake calipers incase any gets onto the belts. hope this has helped, let me know how you get on. if it makes the changes to your car as it did to mine you wont regret it best money i have spent on it yet next job is a 180bhp upgrade within the next 6 weeks or so :worship:

ah cool dude, let me know what it goes like after that remap, i'm really interested to know as i considered going that way if i got the 130jtd

really interested to find out myself mate not too bad at the moment really, especially after fitting a new airflow meter does sub 10 secs to 60 and still over 40 mpg! can't be bad will certainly put my results on show after upgrade

kev,

i am glad that u solve your noisy problem. yours is a 130jtd meaning 2.4? mine is only 1.9 105jtd. how much u spend for the pulley? any sign of damage on the pulley? how to tell if the pulley is o.k? what noise it goes off?

when idling, my pulley is turning very well and balanced. is your tensioner have a 'damper' attached to it? my tensioner is like a 'snake coil-up'. same as yours?

a new pulley cost me about Euro 300 without labour yet. it is very expensive in malaysia and hard to get spare.

anyone can sell on-line worldwide?

hope to hear from u soon. thks.

hi mate, my noise was mainly the sort of thudding noise coming from the belt vibrating badly on tickover. it seemed to be ok above about 1500 revs. yes mine is the 2.4 but the guy at fiat over here said all there pulleys with the rubber insert give trouble, he has sold many replacement ones fro the punto jtd which is basically the same 1.9 engine as yours i would have thought. there really isn't that much to give away whether it was knackered or not although once it was off and on the bench it was found to be quite easy to pry apart the rubber damper section. i paid a few pence over £90 for mine with trade discount. they are quite an easy d.i.y. item to fit if you're competent with the spanners. my tensioner is selve adjusting with a strong spring acting just behind the tensioner pulley, the spring is wrapped in a rubber cover. as i said before, i found the bushes at each end of the spring seat eyes to be worn. there was a mark where the spring seat had been hitting the body of the tensioner whilst in operation. i have altered the position of the bushes in there housing as a temporary solution but am looking into getting new replacement bushes as a more permanent repair. i was sure the tensioner moving so much was a symptom of the problem rather than the problem itself, the vibration from the faulty damping system in the pulley was more than it could cope with. the movement from the tensioner is far less now. hope this helps.

hi kev,

so what u r saying is i can't really tell if the damper is gone or not by visual. i have to dismantle the damper and check it out in a bench.

yeah..it seems an easy job with 4 screw mount on it. but the tools is not really torx. kind of funny.

wow..only 90 pounds! that is about half the price compare what i get here. any idea how much it is for 1.9 JTD? i already check the catalog and yours is not the same as mine.

after replacing the pulley, u find that the tensioner is much stable right? yeah..mine will vibrate less when rpm about 1500. also i find that when cold start, i can hear 'metal' like knocking sound coming out from the damper side. do u have the same thing? just want to be sure before changing an expensive part.

do u think i can get the part directly from uk? any idea? can help?

thks.

those screws use Ribe bits

Torx and Ribe bits are the same. Just one has a hole in the middle.

i think pete would argue that... if it were the case wouldnt need ribe bits would we

Been looking into this and it seems people are using torx bits fine in ribe applications.

:bang: now i gunna have to buy torx bits anyway :bang:

Machinemart do a nice little set for about £7... Comes with an L shaped key for driving them.

hi guys, torx bits and ribe bits are not the same but very similar . the bolts holding the pulley on are ribe type. i bought mine some years ago in a set to do an engine rebuild on my previous lancia dedra turbo. 'ribe' bits have 6 squared off 'points' whereas a 'torx' bit finishes in more of a point . torx bits will undo ribe type bolts as long as they are not too tight, i certainly wouldn't reccomend using them on something so important as a crankshaft pulley which need to be tightened to a specific torque, the consequences of the pulley coming off don't bear thinking about . i have seen sets for sale in halfords stores and they are readily available from most decent car accessary shop or local tool shop a set is useful for modern fiats as i have used them in other areas such as when changing the cam-belt tazztham, i did find a supplier who was selling pulleys for yours, as you say it is different on the 1.9 to the 2.4, i will look back and find them and post the result on this thread for you. as for the tensioner it is quite a basic item once it is off for inspection, getting it back on is a bit more tricky on my 2.4 but i guess you will have a bit more room between the engine and inner wing having 1 less cylinder and therfore a shorter engine on mine there was a distinct metalic tapping noise which was caused by the spring seat hitting the body of the tensioner (clearly shown up by the shiny markings where the 2 had been meeting!) which as i said before is caused by worn bushes in the spring eyes (where the bolts holding the spring on go) hope this is all making sense, its worth it in the end believe me

tazztham, there is a site here in the uk selling the crank pulley for your car for £69.81 inc uk vat (don't know how that affects you) its £59.41 before vat (tax). www.shop4parts.co.uk is who you need. looks like there is 4 bolt holes and one pilot hole for the locating dowel not sure if they deliver as far as you but can't see why not there part number is S4P1022, just enter fiat, marea, engine components, engine miscellaneous into the search boxes. the postage rates they had were for mainly uk locations its quite a heavy item at almost 3kg though so might be costly hope this helps

kev,

thks for teaching me something new. so it is called ribe bit. can't find it here popular at all.

so your noise is coming from the tensioner and not from the damper? damper is the cause of making the tensioner spring wear out the bushes, right?

i will search for the parts. how about anyone selling the ribe bits online?

thks.

Thanks for that Kev. Any chance of a close up image of a Ribe bit with a Torx for comparing? I've tried searching but found nothing good.

i picked up my ribe set this morning aaanndddd my head they gaves me bloody everything with the head lol more than i was expecting
