Tensioner pulley dieing! Have some questions...

  

MC Stang -> Tensioner pulley dieing! Have some questions... (5/6/2008 12:28:01 PM)

My tensioner pulley is making all kinds of rattling and metallic clicking noises and I am pretty certain it is dieing. I've never changed one of these before, how do you release the tensioner arm? Is a special tool needed? Once the tensioner arm is loose do you just unbolt the pulley, and are either of these reverse thread?

Thanks in advance for any help with this.

loosen of the bolt on the tensioner a bit then push it down. You can do it with a rachet extension ro get in there easier.

1/2 " breaker bar really helps to
move the tensioner arm down,
then you can slip the belt off the
alternator with the other hand

My tensioner pulley is starting to squeak on me..  Or maybe it's the idler..  I don't know.  Either way, one of those is squeaking.  Where can a replacement be had?  Is it a dealer only part, or is there anyone who makes a higher-quality aftermarket one??

You need a 1/2 inch rachet with a pipe or breaker bar to attach to the tensioner arm in order to release the tension.  Push on your rachet and slip the belt off the alternator.  Once you remove the belt you can slowly release pressure on your rachet and then just unbolt the tensioner.  3 bolts, 18 foot lbs when reinstalling it.

How do you know the noise is coming from your tensioner?  There's really not much there to fail.

I don't know if you were talking to me or the OP, but mine is a squeaking that goes away as it warms up.  I've stuck my head under there SEVERAL times when it was cold and listened.  It's definitely coming from the passenger side.  Beyond that, I'm guessing it's the tensioner or idler, since the only other supercharged S197 around here locally has also had tensioner issues..

Moosestang:
 
Thanks for the advice on releasing the belt tension. I am 90%+ certain that it is the idler pulley because I used an automotive stethoscope to isolate where the source of the noise was coming from while the engine was running. The noise through the stethoscope was much louder from the tensioner pulley, you could actually hear the metal “grating” within the pulley. The other pulleys where much quieter, though the idler pulley was a little noisy, I’m thinking of replacing it also while I’m at it.

I don't know if he swapped the stock tensioner pulley or the whole tensioner, but you can actually use a 90mm idler pulley on the tensioner.  Whipple has you do this with the 10psi pulley and replace your 90mm idler pulley with the 100mm that comes with the kit.  All that does is take up more slack from the belt.

exx1976 -> RE: Tensioner pulley dieing! Have some questions... (5/8/2008 9:29:23 AM)

Ok, but where can I get the pulley????   Is it a dealer-only part, or is there an aftermarket one available that's better than the stock one?

moosestang -> RE: Tensioner pulley dieing! Have some questions... (5/8/2008 9:52:28 AM)

I'm guessing dealer only.  The 100mm idler that comes with the whipple looks just like the stock pulleys.  It's probably from another ford.

If you are going to get a new tensioner I would get the Thumprr, or Adam's Frankentensioner.  Last one you will ever buy. 

mygt500 -> RE: Tensioner pulley dieing! Have some questions... (5/9/2008 2:11:35 AM)

Mine squeaks until warm up and then it is silent. I read by many (inc modaddict) it is normal and may go away in a few thousand miles. To get rid of it you might want to get an 8 rib belt kit  and/or a new tensioner (nice billet aluminum piece) PM me for details!    J

Others have just made sure it was torqued down right and it went away....mine you cannot get any tighter!

I just ordered the Thump_rrr racing tensioner. As always, I'll post a full review after it is installed. (Thanks myGT500 for getting me in touch with thump.)

Well, how much was it?

If anyone is looking for the 100mm idler pulley that comes with the whipple kit, it's made by dayco and the part number is 89055.

nineinchnail1024 -> RE: Tensioner pulley dieing! Have some questions... (5/9/2008 2:43:31 PM)

$350 + $20 shipping. Not bad when you consider that it is the ONLY brand that has yet to be broken by anybody. Group buys seem out of the question. It's a popular product.
