It looks from your pic that the balancer has about 3/8" to go before being seated...just the right amount of misalignment caused by a dislodged key...

As previously mentioned by others, you should be using a threaded pusher style installer bolt that fully threads into the crank itself, then the nut is tightened to ull the balancer on...

Or you can also use a BFH as mentioned, but room to swing is always a concern...

I did use the right tool (threaded as far as it could go),just my threads gave out just before it was dully seated
