It is hard to be definite about something I haven't seen, but if the pulley doesn't look like the others when running, I'd have someone check it out.

 

Thanks for the advice.

Do you notice anything about your crank pulley at idle that looks like a "wobble" ? And also compare it to the other pulleys. Thanks.

 

It will NOT make any difference. I painted a white stripe on the balancer AND the nut, checked it weekly. STILL fried my car, the DAY after I insured the marks still lined up!

My car was built THREE months after yours.................I think that I would be really careful if I were you. Its a matter of time pure and simple. However, if you still baby it and drive it like a Buick, it might NEVER fail. Lucky you. I for one bought my Corvette to enjoy, as the General suggests.................remember it IS a Corvette, not a Buick.

 

What kind of damage did you sustain?
What kind of an ordeal is involved with the repair? How long did it take them and what's involved? Did you need an alignment?
I am not very comfortable with dealerships.


I have no intentions of driving my vette for Mrs. Daisy!

 

The pulley is a machined casting, and the machined groove isn't exactly parallel to the cast edge of the pulley. So when it turns, the edge of the pulley seems to "wander" in and out, though the groove runs true. This is normal, it is not wobble. Wobble would involve the whole body of the pulley moving in and out as it turns, because it is loose on the shaft.

 

The harmonic balancer is a 2 piece assembly. You have the inner hub thats bolted to the crankshaft and the outer hub that has the pulley grooves on it. They are pressed together with a thin rubber damper sleeve between the two. The slight amount of wobble youre probably seeing is because of how it was pressed together. A slight amount of wobble is normal, which I have in mine as well. If you feel the outer face of the balancer, you will see the rubber lip and can feel it. Its firm, but you can push it with a screwdriver or whatever. Other pulleys on the accessories are a one piece casting and unless the bearings are going out, you wont see any wobble.

 

Thanks Av8ter, shopdog, VNAMVET and everyone else that responded!
Maybe I am alright, not sure. I will have it looked at Tommorow. Thanks.

 

I attended the same customer quality clinic at the C5/C6 Bash that CAPE COD BOB did. GM engineer looked at my pulley and belt. It was starting to fray ,he wrote a note to my dealer telling them to do the TSB fix. Had it done last week. TSB says to allow 2.3 hours, Vette Tech at my dealer who is GM trained said it took him 5 hours. Said my KOOKS headers did not allow him to drop the starter properly. They wanted to charge me for 3 extra hours labor. I agreed to pay 1 hour since the headers did cause some extra labor but NOT 3 hours worth. If you read the TSB and all that has to be done to do the "fix", I think GM is not allowing enough hours.

 

 

I just read on another forum that two more of their members lost the pulley. Wonder how long "those in the know" will hold on to their claim of under a hundred cases? It's hard to prove or disprove both the truth or a lie.

 

Think I lost mine today.

 

Had it checked Today and you were right on the money, The slight wobble that I perceived as a problem is normal!

 

Same here....Had it checked Today and you were right on the money also and your explanation was dead accurate!, The slight wobble that I perceived as a problem is normal!

 

My car started making a whistling noise about 2 weeks ago. Took it into the shop at which point, the drive belt was replaced. The whistling stopped but then the car started to make a rattling noise under the hood. Kinda sounded like someone had dropped a lug nut somewhere under the hood and it was bouncing around. It would only do it for a few seconds in the morning and then stop. I looked under the hood and found that the tensioner pulley was snapping back and forth initially on cold starts and was the cause of the rattling noise. On the day that I got a chance to drive the car back to dealer, the rattling noise persisted after warmup and was actually getting louder. I pulled into the service bay just in time for the noise to completely stop. It was at about that moment that a huge gush of oil shot out from under my car and covered the service bay floor. At least the timing worked out well. Under the hood, oil was coming out of the area around the crank pulley/harmonic balancer. The new belt was also chewed to sh*t along its rear edge. Still waiting to hear about the prognosis. Thank God for warranty coverage.

I also had to have the accelerator pedal assembly replaced due to a faulty sensor about 2 months ago. Got into the car to a DIC message that read: "Service traction system/Reduced engine power". The car drove at about 24 mph all the way to the dealer. Took about 8 minutes to get up to 24 mph. I love to drive this car but am dismayed by the gremlins. 3 service trips in 6 months. People are brave for putting mods on this car and possibly voiding warranties. In contrast, I also have an 03 Cobra that seems bulletproof compared to this Vette. Not a single problem yet.

 

After two crank pulley failures and then getting a free extended engine warrenty from GM I have to agree about not modding this car. I won't give them a chance to void my warrenty.

 

2 crank pully failures??? Were they as dramatic as mine? I guess if it happens again, that would qualify you for a new car under Lemon Laws wouldn't it? This is the only car I've ever had any major problems with. Pretty annoying considering that I paid full sticker in October because of "market demand". We line up like a bunch of idiots for these marginal American cars. Paid full sticker for the Cobra also when it first came out because I had to have it. Luckilly, that car seems to be holding its own. My next car is going to be the new M5 or an E55 AMG. A colleague of mine has a new E55 that'll eat my Vette and Cobra alive. My 745 Li also ticks along without so much as a squeak or rattle.

 

WEEZEL

If you got it in October I take it your VIN is in the range of concern - is that right?

How many miles on it when the crank bolt problem happened?

Thanks, Bob

The car has 4300 miles on the clock. I haven't checked the VIN but I suspect that since my car is up on the rack with front end of the engine and the steering assembly off of it, that my car was in the VIN range. Kinda dulls my confidence in this car knowing the amount of dismantling and ultimate re-assembly that is taking place. Somehow, I don't think that the car will feel "new" to me when I get it back.

 

Darn!

The common wisdom around here was that if you made it past 2,000 miles that you probably weren't going to have a problem. My VIN is in the affected range but with about 8,000 miles I figured if nothing showed up by now I was okay.

So much for that line of thought!

Thanks, and good luck with your car. Pimp 'em for an extended warranty!!!

My pulley took a crap this weekend. I also have 4300 miles on the car. It is getting fixed. My clutch also went out for the 3td time too.
