Hey guys, I've had my Vortech kit on my 05 rev-up G for about a year now and everything is running solid. About a month ago I started to hear this weird clicking noise. The noise won't start unless the car is running for like 20 mins or so. The sound is like a small mouse (squeel/clicking) alot of clicking..lol I know im not good at explaing this so I took a video..Heres the video:




So the noise is coming from the cog belt bearing. Could it be that my bearing is messed up or could it be the gates cog belt thats on there?? This is the picture of the belt.

Please let me know what you guys think it could be. Thanks

 

Your belt looks great . I cant tell what the clicking sound is . Might try the hose or pipe to the ear and the other end on the jackshaft to make sure thats whats making the sound .

 

Well I can tell you this. The bolt on the center idler pulley is backwards. The nut is supposed to go on the other side. There is a good picture diagram on the FAQ vortech thread on how to install it right. As far as the sound goes I can't help you there, but I think having the bolt on backwards can cause problems.

 

Hmmm I did check with the hose and the noise is def coming from the center idler pulley and/or the middle right cog pulley.


I had one of the members on here do the work so I never knew that the bolt was backwards. I have always heard that it can cause a problem.. The thing is, the car hits boost fine and drives perfect.. Just the noise happens after liek 20 mins of driving..

 

your idler pully is installed bolt backwards. try that, if not then you might have to replace the bearing.

 

I'd remove the cog belt and see if it makes a differnce. At least then you'd know if it the blower or the jack shaft. JMO.

 

I actually have the same type of issue. The one side of my cog belt runs up against the "rail" of the idler pulley and wears the belt down to the metal. It makes a squeaky noise kind of like yours, but only when it gets hot.

Looking at the picture of the inside of the belt, I can see some shiny metal showing. Try flipping the cog belt around, and see if the noise persists.

As for a fix - I haven't discovered that yet.

EDIT: I see you said after 20 mins of driving it happens - I would bet money that it's the same issue I have.

EDIT AGAIN: The inside edge of the idler pulley looks like it's worn down a bit from the metal of the belt - which can add to the issue. I realized I had my pulley on backwards (slightly different depending on which way you have it - although your belt seems to sit right in the middle of the two cog pulleys so the pulley should be on the right way, it's just that the bolt is backwards).

 

no no no ! it is only the cog belt...

it's happens generally after a rain... just spray some silicone lube on you cog belt... when it is running... not inside, but outside and it will solve your problem... or your noise...

 

you guys are nuts if you think it matters which way that bolt faces.

 

i'd rather have my bearing spinning on the smooth part of the rod instead of the grooved threads.

 

it doesnt spin on the bolt. if it did then when you tighten the bolt down it would either squeal horribly or not turn at all. whether or not it makes a difference i dont know, but thats not the reason

 

second video:

 

i thought so too but i read a lot about it and apparently it can lead to premature bearing wear if not installed properly.

 

+1

 

just try what I said... spray some silicone lube outside the cog belt...

and you will se the results...

 

+1 Just check out the first page of Sentry's Vortech Sticky, he has a whole section with pictures that explains this. I'm not saying that is the OP's problem but its worth checking out and re-installing properly.

 

you are mistaken... since its a bearing, its not spinning at all where it contacts the bolt. A bearing has an inner race and an outer race. When you bolt it down, the inner race is stationary, which is what makes it a bearing. You are clamping the inner race to the bracket so that it does not spin, and it doesnt matter how that inner race is held as long as you are only holding the inner race and not interfering with the rest of the bearing.

The direction a bolt holding the inner race is facing means nothing at all.

 

if you are only holding it by the inner race, and not distorting the inner race (more torque than that bolt can handle anyway im sure), nothing is going to cause premature wear other than shitty bearings.

 

^^I am taking my installers side on this one. Thanks Charles, I'll be ordering a new pulley soon. This noise isn't crazy but it was just bugging me so I thought of getting everyones opinion. Thanks everybody!

 

d'oh, and duh. stand corrected. either way, no reason not to install as directed. although unrelated to teh OP's problem i bet.
