Harmonic balancer

[Prof]

I just had mine spin off... It did damage my crack. So this time it is being keyed on.

Can't imagine that it was not keyed when Hennessey did the initial twin turbos!!!!!!!!!!!

Are you telling me that it was built originally without keying or pinning the crank???? If so I think we need to start a thread that lists the issues with the initial build on that truck!

OK, so that's not the crank repair sleeve. It's the oil seal repair sleeve on the harmonic balancer itself. On older cars the oil seals on the block and pan can wear a groove in the balancer. I'm guessing the sleeve you have is to repair that and not the crank surface.
