So this is my second freaking belt in less then 100kms of driving this car...WTF...Its starting to take off the belt from the inside (close to the motor) a little at a time. Man I read that this is famous for belt shreading but damn. I did everything by the book, spent 4 hours today to put a new belt/inspect. Couldn't find anything...

not only does this bag not move, its shredding belts. So pissed off...Any insight? Everything again looks lined up, I cannot see anythign that would start to shred the belt. Only only only thing that I do not have installed on the supercharger bracket is a damn bolt that pretty much sits in the middle of the bracket.

(its the bolt hole that's half cut off in the pic), on my bracket its all cut off. Does this bolt play a part in separating the belt?

If it doesn't i'm at a lose of words.

 

I just want to...god. 2 belts in one week...I believe it starts to shred if I boost. I think its good at idle, I have every bolt, standoff, minus the middle bolt which might not even be used...damn

Ill take pics....

 

show us some pics, its starting to scare me now

i havent had any belt issues yet, ive driven a week so far, so probably the same amount of miles. for what its worth, i dont have that middle bolt installed either, nor do i have the standoff bolts in, not saying thats a good thing, but it hasnt harmed me yet either.

what kinda pulleys are you using?

 

3.125" pulley. Just checked it this morning and its getting worse...checked to make sure its aligned and its good...looks like something is eating away at inner middle (bracket side) of the belt.like straight in the middle there is a small grove forming. Again we could not see any signs of the belt rubbing...

I bought this used so it must have worked before...though the person was using a smaller pulley I believe 2.60"..if it freaking fixes my problem id gladly get the smaller pulley...as long as it doesn't under spin the supercharger...

Pics will be added when I get home tonight.

 

Going to purchase this "Toyota Idler Pulley Sub Assy" and the part# is 13503-5011

I hope I can find it/will fix my problem. If this doesn't bye bye $1000 + for matty's V1 conversion kit. Ironic thing is I had his plate before I sold it...ha

Is this pulley still available to buy or has it been changed?

 

well thats what i meant, what kinda pulleys are u using for the idler and tensioner? if you have rails on either, maybe its rubbing up against one of those...

 

somthing is not alligned properly, plus another way to eliminate shredding is shave the middle nub of the V2 plate completely, its really useless. thats what i was told to do, and it worked, i had my car S/Ced for months before i sold it, and it never shred a belt, or you can go for option #2, get a matty V1 plate kit if you have the money to spend.
notice how the middle nub on my plate is gone, thats where your belt is more than likely rubbing on

shave it down, check alligment again...oh yeah, and to take it a step further, replace the small plastic idler on the bracket with an ASP steel idler with sidewalls

 

The tensioner has sidewalls (am thinking this is the problem) and err the idler is the one that JAMAICANLOVRBOY pic shows? if so its the same looking (no side walls). Also my tensioner pulley is steel.

Im going to take a picture right now as I cranked the car to the right spot. id never guess the tensioner pulley would be able to shred the belt in such a manner.

I assure you when I take this damn bracket off again ill remove that damn middle peice like JAMAICANLOVRBOY has it. No more **** ups..8 hours just for removing a damn belt twice...If I stil shred belts after that ill get Mattys bracket.

 

Pics!



As you can see a small piece of belt has started to shred of. This is with me driving the car normally no crazy driving.



Belt is centered on the idler. You can see where its clean metal.



Tensioner, can't see much but the belt rides center.



Tensioner pic of it from underneath the car. The camera angle doesn't give it justice but again its centered, come to think of it I guess its centered to every other pulley. In any case its shredding on the side where it has room...



This is the pulley from the condenser, if you look at right side of the belt you can notice it has a wear on it.

 

Movie Clip...



If you look closely you can see the strands that are startign to come off.

 

Shaving the middle nub is a waste considering he's running a 3.125 pulley. Unless of course all or some of the pulleys are way bigger/smaller than what Stillen had intended......

Check the tensioner pulley. Is it put together EXACTLY how it's called out in Stillen's install manual/SCIFD, and with the parts Stillen intended for use??

 

I havn't shredded a belt in 4 years...and I'm running the V2. The tensioner must be exactly right! I used a belt that was a little shorter than what was called for so I didn't have to run the tensioner out quite so far

 

If I remember correctly this is how I put it on...

Square bolt fitting in square in, tensioner bracket, washer,tensioner tightener, stillen spacer, pulley (does it matter which way the pulley goes in?), washer,nut.

 

If anyone could shed some light on this. Tomorrow im getting in Toyota "Idler Sub Assy" 13503-5011 and was reading and came across this.

"You do actually need to stack up washers inside the pulley in order to bring the nut to an accessible position. No special bolt needed. You only need the pulley and a few washers. In some cases you may have to stack a washer or two behind the pulley as well so it clears everything. Just use your best judgement on it, and you'll be fine. Post up any questions, those who have it can answer and clear up a few things about using this pulley."

Does that mean that the stillen spacer fit right inside it and I would need 1 or 2 washers to have it be pushed in a little mroe to get good access to when I tighten the nut in?

Second question is if i get the wrong pulley (95% chance I get the wrong one) do I go for this Infiniti j30 pulley 13077-F6511?

Thanks

 

i have the j30 pulley and it seems to work ok.

so during all of this shredding, you still dont see anywhere that its rubbing on something? it seems like you oughtta see something u know...

 

If I had to take a geuss based on everything you've said.......

........ See to me that shredding looks like an alignment issue, which you swear up and down that you don't have..........

......... but knowing a thing or two about 4g's in general, when I see that rusty *** crank pulley I wonder how deteriorated the rubber is on that thing..... It's a common occurrence for stock 4g's to shred the belt just like that (on the inside) as the rubber on the crank pulley starts to deteriorate, and the pulleys always look real rusty like yours, I'm sure spinning a blower doesn't help.

 

The car has 144 XXX km's on it. Could be an issue with the crank pulley but to be honest my other maxima with 260 XXX km's never had that issue. Ill look into it and see if it moves any.

Anyone can shed some light on the pulley, does the stock belt tensioner bolt fit right in with the stillen spacer or does it come with its own spacer?

 

well mine shredded when i first installed it, and vadim told me to shave a nub down, i assumed that was the nub he spoke of. after i shaved it down, nomore shredding, so im just saying what worked for me...you gotta also remember that there is a raised part that i also shaved down....kinda sh*t like this make you hate suprechargers.

 

Well, are all the pullies in your system what Stillen provided? (ie same size diameter, width etc) Probably not I'm assuming since you had to shave the center post off with a 3.125 pulley.

As for shaving the slightly raised part, that's unnecessary too unless things are out of alignment. I've studied/analyzed all this stuff ten times over. The system works well if Stillens parts are used, or very, very similar replicas are used. Anything else is asking for trouble.

Most guys who have shredding problems have either installed things (ie belt tensioner) wrong, or have replacement pullies (bigger/smaller with different offsets nonetheless). Not good.

Superchargers are great.

 

I just noticed that my Pulley has 2 side walls. Goes like this. Sidewall, then small sidewall (a tad smaller then the belt height), then where the belt sits,small sidewall, then sidewall.

What I believe is happening is that my belt is sitting on that small sidewall. I say this because you can see where the belt is rubbing off. You compare this to the original pulley which only has the outer sidewalls. So that's where I'm at. I ordered the Toyota pulley coming in tomorrow, if that doesnt fit I have the J30 pulley coming in on Monday. If that doesn't work well Matty's plate it is.

Ohh yah, the belt has 2 sides, a smooth side and a ribbed side. The smooth side is where you can see a wear on it and the tensioner pulley is the only place where the smooth side spins on. I lied the 2 inch idler pulley also spins on the smooth side of the belt but that's not where its rubbing)

yup...just a thought though... How does the stock idler pulley look like?

 

If you need an Idler pulley replacement I recently ordered the J30 idler pulley Part #is 13077F6511A that I cannot use, It is still brand new if you wish to buy it off me.
This is the replacment pulley for the Toyota pulley since it was discontinued according to the stickies.

 

Hey sorry to hear about all the problems. But it looks like someone has butchered my kit to hell and back. The missing bolt you mentioned maybe the one in the center that was shaved down for the smaller pulley. I had a few problems at the beginning with this kit but got it right pretty quick. I know for a fact that the SC pulley is not the one that I had on there originally. I sold this kit with a 1.9" pulley on it. The tensioner and idle pulleys were custom made (along with the SC one) from aluminized steel to OEM specs. I am sure that you are having alignment issues. And the change happens at boost. Remember that when you boost the belt is moving much faster and that if something is slightly off it will really be off and high RPM's. I can't remember off the top of my head, but you may also have the tensioner assembled wrong. If the bolt that you are missing is not the middle one then that might be the cause also. Hope this helps.

 

By the way the pulleys were less than a few months old when I sold the kit.

 

Did you sell the kit to Cli-Max as he claims he never used it., Somethign tells me it may have been passed around after you sold it...sigh...

I ordered one from the dealership and also have the toyota idler coming in today. In any case, if they both fail. I'll definitly buy it off you. I just kinda want it fast which is why I went the Dealer way.

While im on this topic...Where can I get a lower idler pulley say 2.87" from Stillen?

 

Can't remember who bought it. Someone from Canada I think? At any rate, as I said before you did not get everything I sold. So no telling what has happened to what I had. Sorry. I still think you are looking in the wrong place. The side walls on the pulley should not be a problem if the alignmanet is correct.

 

I just looked Cli-Max is who bought it from me.

 

Square bolt, tensioner bracket, washer,tensioner tightener, stillen spacer, pulley (does it matter which way the pulley goes in?), washer,nut.

Thats how I have it installed.

 

That is the way I remember it. When you put the bracket on the car, are you tightening it evenly (like a head gasket) also do the engine ounts bolts first and then wirk your way around.

 

everything is being tightened at the same time. I can drive on this belt for a while if I don't go crazy on it...but its still wearing itself off on one side. Maybe ill try to get a hold of Cli-Max and ask him to look for the pullies. I highly doubt he will contact me as after I bought it form him he never replied ot my pms...

 

Hmm, well Latinamax says he had his setup with all OEM sized pulleys so you may be ok using the OEM parts.
As far as the Toyota Idler pulley I had read that they changed the pulley and the one being sold now is a bit too large for the V2 plate which is why many went to the J30 idler pulley.
I have a V1 plate, I cant use the same pullies as the V2 plate.
Also, if you want a replacement pulley for the SCer you can get them from Vortech or http://www.928motorsports.com

 

So I was in my garage today fixing some paintball gear and saw one of my spare tensioner pullies on the stock bracket. I looked at the washer and well..it looks 1-2mm bigger then what I have. I'm thinking to myself that may affect why its shredding so little... Going to change that tomorrow.

The toyota idler that I got was the same size, but it was ribbed and not smooth...told you id get the wrong one! Ohh well glad I found my stock tensioner, hope that washer will make the difference...Which makes me think...this was the washer that came off my other motor...someone must have lost the original washer and threw in a random one which prolly didn't matter for a stock motor...

Hope this might fix my problem

 

Sorry but just skimmed through the thread...
As for different pullies there is a pic in the instructions:

If you need the original Stillen Installation pdf... email me.

 

I flipped over the pulley (now it sits way better), added the washer which was a hair bigger. Belt isn't being worn out now. But I do see the random 1-2 thin strands coming out which I just trim off (prolly do to the fact it was wearing of before I added the new washer/flipped the pulley). In any case I still have the J30 pulley coming in on Monday. Did a good 5-10 hard pulls + tuning. The car really wakes up at higher rpm. Still dont see 11's only 10s for A/F, getting there!

 

i guess this is why most maxima owners are switching to turbo now, takes a bit more time to assemble parts, but its way simpler, and definately cheaper
