My harmonic balancer wobbles
I can see a noticeable wobble in my harmonic balancer and its causing my A/C belt tensioner to move back and forth. Its been like this for about a month now ever since i did my cam swap. I think this could be because I tightened it down using a pry bar through it and a big TQ wrench to tighten it down. Is this going to mess anything serious up, or just cause me to go through belts/tensioners a little faster than normal?
Also, to fix this, do i need to buy a new bolt and redo the harmonic balancer?

Well I have to drive it, as it is my DD. It doesn't wobble too bad, and doesnt really look bent, but it does cause the A/C tensioner to move some. I'll try and take it easy on the truck and I'll go pick up a new bolt and see what kind of deal I can get on a harmonic balancer at work.

When you but the balancer back on there is a tool to us to get it on correctly and a torque procedure for the bolt. Do a search and do it correctly or you will have another failure. The bolts are a one time use and rather cheap, the torque sequence is something like torque to 37 ft lbs and then measure 240 degrees on balancer and torque to that point. It is several hundred pounds of torque and you need a way to hold the engine from turning. 3 ft pipe extension really helps.
