that doesn't sound good. Did they say how old the pulley was?

 

Since it's been brought up, my 61mm SC Pulley sheared into three pieces a couple of weeks ago; I'm not sure if it was mine that you saw the pictures of though as I sent it to some local forum members but didn't post it anywhere myself. I believe that excessive heating of the aluminum pulley caused points to get weaker overtime and eventually lead it to shear when it was under stress; the air injection tubes managed to keep the pulley from going rouge and don't appear to be damaged other than minor scraping. I have reached out to EC and they had no issue replacing it with a 65mm SC Pulley, I'm satisfied with that offer, I will be stacking pullies at a later date.

I noticed that there were other spots that appear to have weakened on my pulley other than the points where it sheared, if you'd like to check yours for structural stability then I'd suggest removing the pulley (or belt) and checking the groves for what looks like hairline fractures or cracks.

Sorry that I didn't post about this here when it happened, I should have.

Edit: I waited quite a while to put the pulley on after I purchased it, I think I've been running the pulley since early 2013.

 

thanks for the update..... this was a 61mm Eurocharged pulley to clarify correct? The 62mm is known as the Karmann Pulley..... One of those failed a few weeks ago.

 

My pulley was the 61mm EC pulley, I wasn't aware that Karmann was making a 62mm pulley as I haven't been keeping up as well as I should.

 

Karmann is long gone, it is just named after them....lol. But, yes, big difference in the pulleys.... Change your topic Dave.......

 

I'm still not sure that my pulley was that one that he's talking about, I didn't publicly share any info; I told a few other SRT-6 guys that are local then spoke with Eurocharged about it.

 

........................

 

OK, then there may still be another 62mm failure out there> I better stay tuned. The aluminum pulleys, have always been a problem. Code 3 had problems and so did EC. Stay with steel. OK, Dave....how 'bout an update? Was it this pulley or is there another. I don't do the Facebook thingy...for XF's anyway....

 

.......................

 

I mis understood, after he told me about his 61mm and, it looks to be the 62mm now, which I have only heard or seen Red Dog's failure. Who else has a 62mm failing? I haven't seen anything on here about it. I guess I will call Rudy and see what is going on with the pulley. I don't need to launch mine thru the hood.

 

He was thinking that my pulley was the one that you read about, the 61mm EC SC Pulley; he wanted you to change the topic because he thought that the wrong pulley might be taking the rap for this one.

Just to clarify, I thought 61mm and 62mm were interchangeable since the EC 61mm is really 61.9mm; I haven't been online enough to know that there's another player in SC pulley game again.

 

The three stops are the first things that went, I was told that it wasn't anything of concern and it never seemed to cause issue.

I hadn't bothered measuring the diameter of the bearing, and it's on it's way back to Eurocharged as of 4:15PM. Both the pullies and the bearings look damn near identical though between my post and the picture that you've shared.

 

Well, I talked to Rudy, and although he's been busy, he hasn't been told of anymore Karmann 62 mm failures other than Red Dogs..... His seemed to have cracked between the two rivets...... Don't get me wrong, I want to hear about failures, but I just want know which pulley is failing. Aluminum pulleys, have failed, we know that. So, I am asking if these failures are the Karmann 62mm? That is all. I have inspected mine and it looks to be fine....but, if others are having problems, I would like to know who they are so I can find out what to look for. Right now, mine is fine.

 

............................

 

Lets just commission Rudy to make some 62mm SC Pullies out of 4340 steel and be done with things that shear and crack? lol
