I know a lot of us JRSC guys having or had problems with our belts and pulleys and a lot of time we hijacking other threads because of it, so I thought it was a good idea to start up on a thread just about jrsc belts and pulleys. The thread is not only for current jrsc peeps but also for the newbies as well so they won't get us frustrated asking the same question over and over again.

I'll start off with one question, I read around and found a member who is using a goodyear 070775 belt which is 7 rib and 77.5 inches long. I tried a dayco belt that was 77.5 long and it wasn't even anywhere close to fitting onto the 3.4 pulley. The dayco 78.9 belt fit extremely well for the purpose. What I want to know is that anyone else tried the goodyear 77.5 long on a 3.4 pulley or is it because different makers make belt a little bit different in length.

my scissors are not holding together. The hole for the bolt holding it is completely stripped!!!

my theory on this is as follows:

wdsonny and I and others have not had any problems since the initial install of the scissors and the belt. Most of the people having this problem have probably either not tightened that bolt enough or overtightened it or just simply played with it many more times... OBVIOUSLY the female thread on the bracket is VERY weak and the more you go in there and loosen it, adjust the belt tension, tighten it... over and over... will weaken that thread even more. I only tightened ONE... yes (1) time after initial install and have never had a belt go outor even hear the belt slipping at all so i've never had to touch that bolt since. This is exactly why i am hesitant to do ANYTHING... if it aint broke dont fix it right?

I bet you any money if i was to keep messing with my belt tension eventually that scissor thread would get all weak and i'd blow the bolt out just like so many have... The installer for ECIGirlon19z sounds like he is not the best and what probably happened is just that... he tightened the belt several times to try to get it right... in the meanwhile.. weakening that thread something fierce...

just my 2 cents.... flame away :wavey:

I'm using a 3/16 tiny ass bolt and washer to hold them together now. It doesn't take much force to hold it in place. Althought the JR bolt is very beefy, the female (bracket) is very soft and weak. They should have used a flushed design like the allen bolt holding the 2.5" idle pulley coming out from the other side with a nut to tighten it. I did some mcguyver ghetto rig with advice from TT and all is well for now.

I can say that I agree with you that might be the case with some, but not all. Mine is not that problem at all, it is a tensioner problem and always has been. I followed all the steps each and every time and lost belts each and every time. The pulley pulls itself out of alignment when things get tightened down. There needs to be a fixed pulley and the Jackson setup isn't.

you're right its not the case for everyone.. it just seems a bunch of people have had the problems in succession..

1) belt issues which required replacing and/or tightening the belt a bunch of times
2) the scissor issue...

anyhoo... i just ordered K-pro 5 minutes ago from you Chris. I cant wait to get it and start tuning!

There will be an answer soon. I have taken the steps with mine to fix it better than anything Jackson has but I had to remove the power steering to do it. The car is a little harder to turn, but I don't worry about the belt.

I did see the order, thank you, I really appreciate the business!

This is entirely possible. However, it would also be a real drag because from what I can tell, many JRSC installations do not perform up to their potential because of slipping belts. Even Sonny's was slipping although it was not noticeable to him in daily driving. So on the one hand you have a system that is prone to slipping belts. On the other hand you should leave the belt tensioner alone so that it doesn't wear or break. A double whammy.

If you don't have a boost gauge it is very hard to tell if your belt is just slightly slipping by 1 or 2 psi. I understand that my problem is not the same exact problem as all the other owners of JRSC. My problem is the hardware is not enduring as it should. I never over tightened the bolt to the point where it is over doing it. I understand that it is more harmful than good if something is too tight. It's just that the scissors are not built to last for me. I checked my belt tension in 3 separate places: between the p/s and blower, between p/s and crank, between crank and a/c. Those are the 3 longest stretches of distance between pulleys. I can assure you that my problem is NOT caused by bad or inexperienced installer. My family has own an auto repair shop for over 15 years and all of my work were done there with ASE certified mechanics to double check my every move, so this is not a bad installer issue. Then again my problem is in the alignment of the pulleys and the strength/durability of the scissors, not the tension.

I took off my 7 rib belt and currently running on a 6 rib belt. This should last me til Thursday when I go to Jackson Racing research/development automotive center.

It is a base rsx test car that have never been seen by anyone from JR until this thursday. I understand the risks involved with being a tester so I'm very patient with my problems. I know exactly what my problems are in my case.

Other than the belt probelm my car runs perfect. Probably better than most non Hondata or JR owned/sponsored rsx's (not in terms of whp but smoothness and tuned). It was tuned by Hondata not for one or two days but weeks. Thank you

if your car kinda bog on the low end, you got slippage

if you have a boost gauge and when u WOT and your boost goes down, you got slippage

if you do my "a/c queak" routine and u got squeaking belt then u definely got slippage

those are the things that I learned from experiences

OT: oh yeah I've been driving very convservatively and boi I tell ya the gas mileage is great. I tried my best to stay in the 3 - 4k range and not hit the vtec(yes I know it's very very very irresistible so I had to do it but rarely). I'm going to do another trial.

Well, I went out of town with my JRSC rsx this weekend, and all is well on my belt. I got to Peoria on Saturday and later on in the day I noticed a little bit of thread type material coming out of the belt on the passenger side. I thought great, now I have a problem and I am an hour and a half away from home. Keep in mind the ribs were all fine on the belt and the rest of the belt looked fine. So I drove it anyway , because I have 2 extra belts in the car at all times. SO after about 3 hours of messing around, I decide to check the belt again. The little threads were gone. The belt looked brand new. Almost like it fixed itself. Has anyone noticed these threads? Is it just the belt breaking in? Maybe it is karma since I've had so much bad luck that it is turning into good luck? I don't know. Anyway just wanted to let everyone know my progress with the problems and hope everyone gets theirs figured out. Good luck again.

I am not sure. It was either that or the p/s pulley and blower pulley. I don't care. It is running like a champ now.

okay so installed the boost gauge and have been monitoring it... at idle it is like around 15-20 vac... then at partial throttle it is 0psi. At 3/4 throttle it is 5psi and at WOT it goes to 7 right away... then eventually hits between 8 and 9 right before i shift.... this is good!!! I have the 7psi pulley and am getting 7+ psi for a good part of the top end... w00t!!!

that's a first lol, I think my guage only read over 7psi once in a while, but good to hear tho lnman

OT: I just finish another tank of gas, I did a trial on both highway and city driving, I filled the car up and it took 11.3g and I was at 340m on the speedo.

So 340/11.3 = 30.08mpg, that's pretty darn good I think :thumbsup:
