Balancer Install Gone Wrong

[68_Step]

Sunday started out good... Until I started to the installation of the new harmonic balancer. I got it from Summit: http://www.summitracing.com/parts/sum-161350

I took the old balancer off a few days ago, no problems. I do not have an balancer installer, only a puller. According to the instructions if I did not have an installer I could heat the balancer in boiling water for 15 minutes to expand it it a bit, then put it on the shaft aligning it with the keyway and using a piece of aluminum (I used wood) to protect it drive it on. It started on alright then just stopped - I have it a couple more whacks and it did not move.

I decided that I would just take it off and try again. It would not come off - I broke the puller. I now have a balancer that is mostly off. I have ordered a new puller / installer kit. With any luck FedEx dropped it at my front door a few minutes ago.

Could the key have gotten misaligned and pushed out the back when I was putting it on? Now I am wedged? Any thoughts or opinions would be appreciated. 1st pic is how far I got it on, the 2nd pic is how far I got it off.
