Balancer slides in on install

That’s a HUGE swing from the biggest to smallest crank.

The .0004 isn’t so bad but .0011 is a mile when the press fit should be (as a general rule) .0005-.0010.
What exactly are you saying? Maybe I am misunderstanding, but I am also getting some numbers from elsewhere and I just want to find a decent range that hopefully lands me in the middle. I am also going to measure the inside of the balancer.
