my balancers bolt came out the other day and needless to say messed some stuff up. i need to know the diameter of the crank where the balancer fits on it. i need to make sure there was no damage to the crank so if anyone knows the diameter of the crank and the inside diameter of the hub that hooks on the balancer that would be awesome. thanks in advance

 

stock motor? I had that problem last year. Stupid GM didn't key the hub to the crank, so mine spun, and the bolt unthreaded itself, and I was going down the road and BANG! It took out my y-pipe, and also dented my k member to ****. I have several dents in the unibody too. I was pissed. I had a stroker though, so luckily I wasn't spinin the crap out of it. That was a sad day. the motor had to come out, the crank got sent out to make sure it was ok... lots of work and a slightly bent crank. They straghtened that baby out good as new...
But no I don't know dimensions... sorry.

 

ya my tranny got a chunk taken out of the outer casing and bent my K member but i wasent spinning the motoe very hard only about 1500 rpm's but hopefully there was no damage to the crank just to the hub. if anyone else has the dimensions that would be great.

 

Does any body know the torque spec for the bolt that bolts the balancer on to the crank

 

Are you saying you had the stock balancer hub on a stroked engine
