Thread: 300 Tdi Penny Trick ... Again

Have done it with 5 cent coin. i loosened the bolt and moved the pulley out with a thin screw driver to locate the sweet spot. WARNING: This is a short term fix only lasted about a month before the bearing seized solid. i have tried many methods but you cant beat changing tensioner. Even changing your belt or cleaning out the grooves may help. Try this before changing the tensioner.

Yep 5 cent coin first , If that doesn't work try a thicker coin , Mine has been fine now for 40000 ks
I did change the pulley bearing before I tried the coin trick , So short term or not i still have the coin behind the tensioner and not worried about it

Hey Mate,

If it is anything like mine it could be that the bearing is nearly cactus. Mine ended up completely seizing on the way home one night. I realise mine was the idler pulley, but they are the same bearings in the end. You could just try chucking a new bearing in there. In the end they are cheap as chips and they do die over time, cheap security really.

Thanks guys
I've got a new belt somewhere, I'll put it on and try the 5 cent piece.
Chris, I'm pretty sure it's just the belt, it goes away as soon as I give the underside of the belt a quick spray of water, or as soon as the engine warms up. No bearing hisses or rumbles after that.
It's just not a good look to have all of the neighbours lights come on when I start it up early in the morning

Just thinking out loud but if a new tensioner or bearings dont stop the squeal , could it be the tensioner mounting stud is bent ?

I doubt the locating stud is bent.
My Disco sounded as if it had a small collection of native birds under the bonnet for a while. I fitted a new bearing ($5 on ebay from the UK) and put a 5c coin in the 9 o'clock position when refitting the tensioner. No noises since. The bearing was making the majority of the noise, when it came out half of the local bog hole came out with it

Give the bearing a go first, its cheap and easy. If that doesnt fix it a new tensioner may be in order but that isnt too hard to do either.

There has to a reason why there is still misalignment even after a new tensioner, stud is the only component mounting it unless the whole front is off kilter.

Completely agree. The coin trick is really meant to be just temporary until you can sort the actual problem. I can't see it being any good for the components over time.
