For those not familiar with the terminology, the harmonic balancer is an interference fit.
It's actually a hair smaller inner diameter than the crank snout outer diameter so that guarantees a TIGHT fit, and the woodruff key in the crank locks it in position from having any chance of spinning.
Sure, they go on hard, but they are supposed to be that way.
I have seen many idiots hammer a balancer back on and they always wonder why they have problems later.
