Someone please kick me in the Head here if I am wrong with what I will post up, but I do not see any advantage to a balancer that is such a tight fit on the Crank snout that it needs to be pressed on and off.
The keyway to Crank slot should be a nice tight fit and the keyway into the balancer slot should be a tight fit in terms of degreeing accuracy,
The proper keyway fit should call for the balancer to be lightly taped on with the wood end of a hammer.
With a Pontiac set up and that large 160 psi torque on the balancer bolt its so high that it compresses that main steel section of the balancer a few thousands and holds it in place.
So like I posted, I see no plus side to a pressed on Pontiac balancer, only a negative with the extra work and steps involved in getting it on and off.
