Ok.

Getting a little tired of changing belts on this thing. Although it takes me only a couple of minutes, it just gets old. I think I may have found out why it's eating belts.

Last week, I had a audible "clank/knock" noise coming from blower area(P1SC). Upon inspection, noted that the PULLEY bolt, **SEEMED** like it may have been loose... after inspection, and pulley removal, it seemed as if the pulley KEYWAY had not been holding the pulley in it's proper location. It looked like it had almost been spinning on the shaft, judging by the wear marks on the inside of the pulley. So, I had another pulley here, so I swapped it.

Everything seemed fine. One week later, and two belts(one saturday, and one today), I popped the hood again, to find that the pulley seems to have that play in it again. When I remove the pulley, it has the wear on the inside of the pulley, like the other one did. It's a sloppy fit, even with the keyway in. Is it just not tight enough(i believe it is). Am I missing a washer or something? The kit is used, and I have had problems with it since day one.

Is my KEYWAY inproperly sized?

Is there something wrong with the shaft?

I know the pulleys aren't the problem.

Also, looking at the pulley, there is an obvious difference to each side of the pulley, one side has a long shaft, one side is shorter. Which side goes towards the blower?

Any insight on this, i'd greatly appreciate it. If pictures are needed, I can probably do that.

Thanks.

There should be a washer under the bolt. If you don't have one, that would be a problem.

If the pulley is on backwards, it will eat a rib off the belt or toss it very quickly the first time you get on it. I found this out when swapping pulleys. I ASSUMED that the stamping for the pulley size would be on the same side on all pulleys. WRONG.

Also, there should be no damage to the keyway or key.

 

Thanks for your time/reply.

I do have ONE washer, which goes between the bolt, and pulley.

Do you know which side is which on the pulley, does the longer side go on the lower side, or the engine side? I don't think either of my pulley's have any numerical indication of size.


Also, just noteing, the SHAFT, receds about 1/16th lower then pulley. In other words, there is a ridge from the shaft, to the lip of the pulley. So, even if I use the washer, it seems there would be a gap between the washer and the SHAFT. Does that make sense the way I worded it?

 

...it also seems like there is too much with the pulley on the shaft as well. Even with the bolt and washer off, only the pulley and KEY for keyway, and it has a weird loosness.

Dunno but...this would be belt number 8.

 

I'm at the limit of my knowledge here. I'm sure a procharger expert will be along shortly to assist you

I'm pretty certain the shaft shouldn't stick out of the pulley, so that should not be a problem.

When I installed the pulley backwards, the belt jumped off and was not visibly aligned. If the belt is running true, I don't think thats a problem.

Possibly the washer is crushed?

Sorry I can't be of more help.

 

I would contact Bob @ EPP.

 

Nah man, I appreciate any and all insight. You've obviously worked on your own car, in turn, giving me your personal experience, which is all I ask for(real answers). Thanks for your input. Again, I appreciate your time.

 

looking at it again, and again,...it almost seems like the KEY itself, is worn. Anyone have an issue like that? Anyone know where to find replacement keys for the chargers?

Gotta start somewhere.

Thanks for any input.

Thank you for your help Tony. I appreciate it.

I think I just solved the puzzle. I tied another pulley, with a new keyway, and it seems to be a solid fit.

Soo, I need to order a new pulley, since my original one is smaller.

Again, thanks for the help.

I can get the pulley and save you some money. I keep most of the sizes in stock. A belt should last you a year or two, so it sounds like you have an alignment problem. This car has been on the same blower belt for over a year. http://www.exoticperformanceplus.com...Car.php?car=40

When properly aligned, the belt should be centered on the pulley's. If it is riding against an edge of a pulley, then that can cause the belt to wear out prematurely. If it is riding against an edge, look to see what can be done to space the pulley to where the belt will be centered on the pulley. Keep in mind that a new belt will stretch, and should be tightened back up after the first hour of use. These belts need to be kept pretty tight, failure to do so will cause belt slippage which creates black dust that can be seen on the blower housing. Bob

 

Thanks for the reply Bob. Couldn't agree more with you. QUick story, this kit I bought used. It's an original procharger twin intercooled setup, which was designed for the single fan setup, instead I used the radiator mod, with larger pipeing, and my original fans. That doesn't matter though...

...now, heres the problem. When you, or anybody looks at the kit, it appears to have a a slight twist, or bend to it. What I mean is the bracket that the head unit/transmission is mounted to. It just LOOKS like it's not in alignment. It's soo close, it could be an optical illusion,...I dunno. I have been in contact with a procharger engineer, on certain issues but, he no longer works there. I already swapped the OLD BILLET pulleys(idlers) that came wit the kit.

I'm gonna see how my wear looks this morning,...if it's visible, i'm gonna have to start saving for a new bracket. I do, however, have the new PROCHARGER bracket, minus tensioner and billet spacers. Maybe if I use that, I could save some money.

Anyways,..sorry for the randomness,...i'll give you a call sometime today. Pulley's go for about how much?

Thank you for your reply and time.
