The threads referred to above by "Let the ride decide" are for an earlier model and the removal procedure is different, that one appears to be behind the fan pulley like most if not all other models.
As far as I am aware the harmonic balancer set up on the 626/633 models is unique to that model and brought about by the fact that Packard "shoehorned" an eight cylinder engine into the space designed for a six. A couple of extra inches between radiator and scuttle would have made a big difference. The same problem exists with the 626/633 front mounted water pump, its an awful design made necessary by lack of space
I agree with Tim's comment about adjusting the rotational interference, I have sought that information for many years without success.
