HI!

So I had that rough pulley install last weekend where I couldn't get the pulley on easily, and tugged a bit, etc etc. You get the idea.

Anyways, now the s/c pulley gives a noticeable chirp when the clutch engages in the morning. This will happen for about 10 minutes before the car heats up. After that there is no chirp on engagement.

I'm sure its the clutch/pulley engagement because it happens exactly like Woody's video shows of when the clutch engages, and it also started the morning after the install.

I used both spacers during the pulley install. My spacing seems correct, but its not entirely even throughout the pulley backing plate. Im at maybe .01 inches at one point to .20 inches at another point.

I don't think theres a problem but, I could be wrong.... Opinions?

 

ohnoesaz, that is .190" out of alignment. That is bad. I would take the pulley off and re-install it to get it on straight. A couple of thousandths is not a big deal and shouldnt affect function. 190 thousandths means that your clutch is not engaging flat and will wear one side MUCH faster than the other. I would expect that it wont grip as well as it should either. Hopefully you didnt bend anything on the initial install. Hope it all works out good for you.

Well, dang. Thats all I have to say.

I can try again tonight, but... The tolerances are so tight that I don't see how it could be installed wrong, which makes me think I just plain damaged the backing plate...

 

when the magnet activates the entire contact point on the pulley will grab. Did you use oil or anthing on your pulley when you instaled it? No one elses pulley squeaks. I would call code3 and ask them to see what he says.

also, is your belt loose?

 

Hey Oz
My Code 3 pulley bolted up just like yours, varying clearances.
Here are pertinent parts of email exchanges with Brain at Code3.

ME: I do notice that the clearance on the Code3 pulley varies in distance between the back of the pulley and the supercharger as if the pulley wasn't completely seated properly. I have installed it a dozen times and the variance is always there. The stock pulley clearance distance is even and the pulley mounts perfectly straight.

BRIAN: As far as the spacing, its only a problem if there is rubbing. Even then, a small shim will fix the issue usually.

BTW my pulley also gives a slight "chirp" when it engages, sometimes.

 

Interesting stuff...

And in fact, I didn't know the pulley backing plate moved to the clutch, I thought the clutch moved to the backing plate. Wow! Such great info you guys have.

Also... I did use WD40 to get the new pulley off when it got stuck on the shaft and I couldn't move in either direction. I dried it off pretty well though.

And thanks for the email from Code3 regarding your issue. Exact same as mine. I'm considering removing one of the spacers to tighten things up. It doesn't appear that it will rub.

And for my belt, its on as tight as it can be since the tensioner is pre-set. But just to note, I installed a new belt with the pulley, so its possible uhm theres some sort of break-in period, who knows.

 

I also put on a new belt with my c3p. Reason is (don't tell anyone) when I finished the install I must of missed one of the pulley grooves on one of the pulleys. Chewed one rib right off of the belt!
Realized that the next day after I had made a 150mph jaunt!

Problems aren't with the belt as long as you have the correct one.

I also had to spray my c3p to get it to go on BTW.

 

THe gap from the driven and driving plates should be parallel. WD40 can cause the clutch to slip and cause a glazed surface, spray it off with carburator cleaner "in a can" to wash it with a catch rag under it

If yours is wobbly pull it and return for evaluation and or replacement as you dont wanna stress the S/C input shaft. Use the washed stocker till its straight, dont want issues.

Woody Enjoy

 

Hey Woody!
I don't think it's an issue of "wobbly". My pulley mounted perfectly straight the problem was the gap between the supercharger "flywheel" and the plate on the pulley that engages the SC flywheel. Just looked at my pulley and the uneven gap that I had has worked its way into alignment where the gap is nearly even now. I attribute the initial uneven gap to the tabs that connect (riveted) to the pulley and the pulley's moveable plate. Over time it seem they will settle into proper alignment. Initially I used all of the shims supplied with the c3p I have since gone to just the original two that were on my stock pulley.

 

Way too many problems with Code3 pulleys. And it was supposed to be so easy to install! Anyone interested in upgrading pulleys for more SC power should look to the more established products. I have had zero problems with my ASP 178 pulley upgrade and have not heard or read of others with significant problems so far. Good luck for those who have not had any problems so far.

 

what is way too many problems? it looks like a couple of people that had some installation problems with a pulley that takes 5 minutes max to install.

there are all kinds of water pump pulley failures on the others, you can try and sway your opinion either way.

it seems to me both are a good option, neither is perfect. i am just glad to have a choice that is actually reasonably priced.

mine works flawlessly and my car runs great. what are your track times by the way?

 

It is easy to install. It's such a well built part that I cannot foresee any problems related to the pulley itself.

I had problems with heat after the install but I would have had them regardless of which pulley system I went with. So far no problems since I mounted the heat exchanger higher up in the airflow.

I love my Code 3 pulley!

 

dstuart sounds like he may possibly be an employee of one of the other pulley manufacturers posting up some misinformation to try and sway some $$ towards them.

 

And I might sound like a Code 3 guy!
(but I'm not, honest!)

 

There were no 178 pulley problems at all. It was 181 and 185's and at this point the amount of problems from both are about equal.

 

My; my; my; aren't we touchy now. I do not think I am posting any " misinformation " Why don't you do a search and see how many times people have been posting problems with code3 pulley vs other pulley systems?

 

my my my why don't you do a search and see how many times people have been posting problems with the crank pulleys?

It has been 2 people with very minor problems which by their posts sounds as if they do not possess vasts amount of mechanical skills.

As opposed to water pulleys breaking on the crank pulley sets and nearly causing catosrophic engine failure. Yeah I see your point, a squeaking pulley is MUCH WORSE than catastrophic engine failure. Great job man at saving this guy from such a horrible fate.

all the pulleys out there do a good job, deal with it. just because it may cut into your sales a little does not mean you should try and post up misinformation in attempt to scare people into purchasing something you must sell.

 

If a search was performed, the Code3 would likely win.

 

I could care less what pulley someone purchases for their car, they all work well. I do care however when someone attempts to post misinformation, that is uncalled for.

Regardless, I love my pulley and if they make a 170mm crank pulley down the road I will add that to my mod list as well

 

I believe LET and Code3 are becoming partners - Jerry even endorsed Code3's products...ASP wouldn't even bother to post here....

That's a pretty sad statement to make...
