Can a crank pulley be turned by hand?
The only pulley you can’t turn by hand is the crank-pulley itself. The tensioner pulley itself might be bad. You would feel bad bearings inside as you turn the pulley – this one should spin easily. Any roughness or looseness indicates a problem.
What causes the balancer on a Buick to wobble?

The harmonic balancer often serves as a pulley for the accessory drive belts turning the alternator,…
What does an aftermarket crank pulley do?
An aftermarket crank pulley can be used to increase the horsepower of a vehicle. These pulleys are designed to weigh considerably less than the pulleys that come standard out of the factory, largely because they do not have harmonic dampeners installed.
