The present invention includes a rotor assembly comprising a shaft, a first component coaxially attached to the shaft for performing a first function in the rotor assembly and acting as a first counterbalance weight, and a second component coaxially attached to the shaft for performing a second function in the rotor assembly and acting as a second counterbalance weight, whereby the first and second counterbalance weights combine to balance the rotor assembly. The present invention also includes a method of balancing a rotor assembly having a shaft and a residual imbalance, the method comprising the steps of coaxially attaching a first component performing a first function and having a first counterbalance weight integral therewith onto the shaft, and coaxially attaching a second component performing a second function and having a second counterbalance weight integral therewith onto the shaft, so that the first and second components counter the residual imbalance.
