CA lightweight oversize crank pulley
Does any body have any experience with the Cobalt Addiction oversize lightweight crank pulley
i have bad experience with it I've tried it twice and both times had bad luck with it on my car (2 different sets)
both sets loosen and broke with as result damaging the key on the crankshaft and the oil pump of my car.
any opinion / experience?

As we had stated on the phone please send us some pics of the damaged part so we can see what might have been the cause . Only problem ever associated with any crank pullies is the crank bolt that GM recommends to replace. Many people have had no issues reusing them as we have been running the stock bolt on our test car for over 3 months now and over 12,000 miles. We reused the stock bolt to make sure it would work with no problem as we figure most people will use it as a short cut and a money savings.
There are a few things people can mess up on while installing the pullies if they are not observant. The pullies can look like they are all the way in tight but if the keyway is not lined up correctly it can trick you into thinking it is all the way in when all it has done is just clear the oil pump sprocket and not fully seated. If not fully seated correctly the pulley bolt will never lock on the keyway thus letting the crank bolt loosen in time. This could happen on EVERY CRANK PULLEY MADE - EVEN STOCK!!!!!!!
We would like it if you could send us pictures which we asked for the first time and the second time you had a problem so we can diagnose what might be wrong with your setup. Everything without pictures is just pure speculation. Please call us at your earliest convienance tomorrow and also email me the pictures to kenny@cobalt-addiction.com
We have been trying to help you , we just need some help back ....pictures please so we can diagnose your problem and not cause a mass hysteria of a defective product.

Not mad at all, just want to help the customer . His first problem was reported to us over a month ago and has left us worried and carrying as to what the cause may have been. Just like when a family member calls you and says there is a problem but doesn't say what, how or why. We have been left wondering for over a month with no info. Then to see a post about wanting help and we have been waiting anxious to help was alarming. Especially how posts gets misinterpreted on these boards. We don't need people worrying about faulty product when we have so much invested in these. We have to worry about intentions on these boards as there has been alot of bashing going on lately and when we have waited for over 5 weeks for pics we have to worry about intentions. We aren't mad and want to help. We just also have to be cautious

I think people are misreading what they want into this post . The idea is we want to help , we are here to help , we have been waiting to help . We arent jumping anyone or anything. People look into statements as they want and online a certain feeling or emotion doesnt always come across right. The only thing we can be blamed for here is CAREing too much to want to help the customer. We are trying to help someone and be as clear as possible with trying to help them and guide them.
The point of these posts are We CARE deeply about the product and about WHAt is going on with his vehicle. The second time he reported a problem was the day before christmas and i was worried the whole holiday and checked my work emails constantly to see the pics of what happened so we could diagnose the problem as quickly as possible and try and get his car back running Quickly. Through the whole holiday i constantly checked the emails so i could get him an answer as quickly as possible. We have been worried about what happened and want to know the Cause and Solution. That way maybe it can help someone else out also. The quicker we learn of a solution or a inherent installation problem the info can be passed on before someone else may have the same problem .
To me an issue like this is EXTREMELY URGENT . Possibly my sense of urgency of getting the pics was a bit OVER THE TOP .....But you guys fail to realize this is my business , my rep and MY LIFE . If there is a problem i NEED to know and HAVE to come up with a solution BEFORE possibly someone else runs into the SAME issue.
IF you don't want to use us as a vendor that is your choice ofcourse , but i think you may be misinterpreting our extreme care and urgency for something else . We are not trying to intentionally treat anyone badly here . If anything came off that way i do apoligize greatly , we all do have emotions and the hardest thing with online is conveying the correct ones through words that can come across wrong.
I JUST WANT TO HELP OUR CUSTOMER OUT WITH HIS PROBLEM AND MAKE SURE NOONE ELSE EXPERIENCES THE SAME THING ...thats all .....and i need pics to do it - I was trying to portray urgency as it has been a long time to wait for pics of an incident that happened 5 weeks ago and then again 3 weeks ago.. This problem has been haunting me since his first phone call 5 weeks ago and i want to solve it so i can sleep better at night and his car can go back to racing.
I love these cars and our customers but these boards can be ruthless!!!!!!

Damn...
I think half you guys just love bashing vendors, CA has done nothing wrong in this case. He was very polite and simple informing everyone that he was aware of this problem and that OP hasn't made much effort to resolve it

CA I agree 100%. When installing L61, LE5, LSJ, and LNF pulleys....you need to be paying close attention, and making sure that everything is lined up, seated fully, and tightened correctly. Also, I WOULD NOT reuse the stock crank bolt. Since the stock bolt is tightened to Yield. That is why GM recommends replacing the bolt. If you do not replace the bolt...some WILL have problems. I have researched this subject a hell of a lot more than most.
The below pic is from a GM performance build book.
The below pic is from a GM performance build book.
The yield strength or yield point of a material is defined in engineering and materials science as the stress at which a material begins to deform plastically. Prior to the yield point the material will deform elastically and will return to its original shape when the applied stress is removed. Once the yield point is passed some fraction of the deformation will be permanent and non-reversible.
In the three-dimensional space of the principal stresses (σ1,σ2,σ3), an infinite number of yield points form together a yield surface.
Knowledge of the yield point is vital when designing a component since it generally represents an upper limit to the load that can be applied. It is also important for the control of many materials production techniques such as forging, rolling, or pressing. In structural engineering, this is a soft failure mode which does not normally cause catastrophic failure or ultimate failure unless it accelerates buckling.

Like CA has mentioned above I didn't sent pictures of the first time, because I took the responsibility completely for my self but its not true i didn't say what, how or why. After the first time I putted the original back on the car and drove it some days and also has raced with the car everything went fine. (This indicates that it was correctly installed because otherwise I would get the same problem with the stock pulley)
I thought by my self let me try a new set again because maybe we did something wrong which wasn't the case for so far we know but I took it on me. I decide to buy a new set (got extra discount on the 2nd one) and be extra careful installing this one and following al the suggestions I got at CA and the info on the internet (http://tunersource.gmblogs.com/Racer...LSJ_Chap_6.pdf pages 118-120) and from the repair manual. but for my surprise doing everything carefully I got the same problem with the second pulley set but this time Ive noticed it earlier because I was monitoring it closer but not in time to prevent all this problem from happening. What I can assure everybody is that with the 2nd set we were extra careful doing everything and everything was correctly installed. The reason for taking so long before working on this problem now is because people of the garage that has worked on my car went on vacation out of the country at the end of the year for 3 weeks and they are back this week to start working.

Wow! The dude asks a question and you get all butt hurt. Since my post may be misinterpreted I'll just say this. Jumping the guys **** like this, when his post was not directed to you, or at you, makes me concerned about the type of service I would receive from you guys. Since I don't mind paying a little extra for quality customer service I think I will do my shopping elsewhere....for now.
Your a punk. why would you even post? you dont know what your talking about cause CA is a respected and respectful vendor. why would you even threaten him by saying you will do your shopping elsewhere....for now? *snickers* your a punk.

Although you are right, I think your still a little to much of a newb to be calling people out like that...

dont worry about how long ive been a member to this forum. its not about being a "newb". what makes me a "pro?" having 1,000 posts? or being on this forum for 2 years or more. It wasnt so much of a call out as much as it was defending CA. CA is good people.
