Zaag Posted February 24, 2010 Share Posted February 24, 2010 Hi all, Thanks to this forum I got rid of that nasty queek under the bonnet which was the tensioner bearing (probably never would have found that on my own so many thanks!). The above was tackled about 2 months ago and it was pretty quiet under the bonnet since then (as far as a 300 can be quiet...). The last two days a similar squeek has developped and I wonder what the next "logical culprit" is... A quick inspection showed some noticeable play on the aircon belt idler (the fixed one). Is that indeed the most logical one? How about the bearing on the aircon belt tensioner arm? I see that there are loose bearings for the fixed one on Ebay as well as as a complete kit which comprises the above two + a bearing for the other tensioner arm which I have replaced already. Are these bearings indeed as easy to change as the sellers claim? Being located in Holland, I would like to get the right parts as they are not that easy to get overhere and having them shipped over from the UK takes a while. What is the wisest thing to do in this case? The old lady has almost 250.000 miles under her belt, if that is of importance. Would be grateful for any advice!

cipx2 Posted February 24, 2010 Share Posted February 24, 2010 I'm sure you can find the bearings locally (see Les' thread about replacing the bearing on the serpentine belt tensioner in the tech archive for complete SKF designation - those are the best bearings for the job I know of). Yes, all 3 bearings are the same and it's easier to replace the 2 ones on the AC belt than on the serpentine belt tensioner (they have normal circlips). One other reason for a squeak is the AC belt tensioner wears out (like being made of chocolate) - the belt 'digs' a groove in it. Do the water test on the belt near the tensioner to see if that's the case. If yes, put a thin washer on the bolt between the tensioner bearing and the arm to bring the wheel forward a little bit. Or get a new tensioner to do it properly. Quote Link to comment Share on other sites More sharing options...
Zaag Posted February 26, 2010 Author Share Posted February 26, 2010 Great! Thanks a lot! Off to the local SKF dealer it is! Quote Link to comment Share on other sites More sharing options...
Zaag Posted March 1, 2010 Author Share Posted March 1, 2010 And UKP 14,64 VAT included does the trick for two SKF bearings! Did I already mention that I LOVE this forum? Quote Link to comment Share on other sites More sharing options...
Zaag Posted March 7, 2010 Author Share Posted March 7, 2010 Hmz... Just took off the idler wheel only to find out that "my"version does have a snap ring and not a circlip.. How the #$%^&*^% does one get that snap ring out of its groove? Quote Link to comment Share on other sites More sharing options...
cipx2 Posted March 7, 2010 Share Posted March 7, 2010 Either use 2 small screwdrivers (pointed tools) to get one them behind the snap ring or use a pair of circlip pliers in between the ring ends and rotate it to force one of the ends towards inside to insert a small screwdriver behind it. Then work your way behind it all the way. Watch your fingers and eyes! Quote Link to comment Share on other sites More sharing options...
