Supercharger belt shredded!

I was just wondering what's the best route for identifying my exact length of my belt?? Here is a pic if it helps..

I know y'all are gonna say measure what you have.. Lol well that's it I got lucky to have that much.. I guess I didn't have it tight enough or was just old.. But I was hammering down and giving it Hell..

I always use an old belt. Cut it to length. And then tape it together at the right length. Then take it in and match it up.

It should be a 55 1/2 belt with 10 ribs.

A lot of people use string. But I find the belt technique more accurate cause it sits on the pulleys like it should.

I'd be concerned about why, but if it was old and loose then it may have been slipping badly and just overheated?

Cheaper by almost half at Ryder Fleet Products

How can I tell when the belt is at the correct tension?

They measure the force it takes to deflect the belt a predetermined amount to set the correct tension. You may have to contact Paxton to see what those specs are.


You don't want to run the belt to tight or it will damage the SC and other accessories from too much side load.
To loose and the belt will slip and eventually shred.


If you have a spring loaded belt tensioner, there is not much you can do about the belt tension unless you remove it and fabricate your own idler pulley, belt tensioning system.

It's a tensioner that I loosen the pulley a lil then with a 10mm turn a bolt threaded through the back of the pulley bolt makes it move up and down to put tension on the belt.. I can add as much as I want

Then we need to find out how much tension is needed.

I don't know what Paxton recommends but usually the longest area about a 1/4" of deflection.

I was unable to find any exact belt tensioning specifications, so I emailed Paxton to see what they have to say about it.

Ok, Paxton replied and said, "You should have a ½ inch deflection on the long side of the belt."

I emailed them back and asked them how much pressure should it take to deflect the belt that 1/2", and so far no reply back.

So I called Paxton.. And they said, " to apply pressure with fingers on the long side of the belt." which means crawl on the ground and reach up to check then lock pulley in place when 1/2" deflection is reached.. I just got it back together and it was almost in the right spot.. I added 3/8th's tension and it is a 1/2" now!! Time for a cruise tomorrow..

Seriously?
That's the strangest way to set belt tension I have ever heard of and I'd almost bet doing it like that will leave the belt to loose.


Here is what Gates Belts says about Micro-V belt tensioning. Notice the range? Quite a bit more than pulling a 1/2" of slack in the belt then tightening it eh?

I guess you can always try the squeak test method if what they told you does not work or it lets the belt slip.


Tighten the belt by feel, then squirt it with water. Rev the engine under load (driving) and listen for belt squealing. If you hear it squealing, tighten it up a little bit.
The water simulates rain and the slipping it might cause on a belt that's ok when it is dry, but is just a bit to loose for wet weather. If your belt is adjusted so it does not slip when it is wet you should be good to go.
