This paper studies the process of eliminating large nutation angles arising from inaccurate initial rotation or imbalance of the spin-stabilized spacecraft using passive auto-balancers (pendulum, ball and liquid). An analogy in the operation of various types of passive auto-balancers (nutation dampers) (pendulum, ball and liquid) during removal of large angles of nutation was established. For pendulum, ball and liquid auto-balancers approximate law of changing large nutation angles in the case of axisymmetric and non-axisymmetric lifting body was obtained. It was found that the rate of changing the nutation angle is significantly affected by the ratio between the axial moments of inertia of the lifting body and the coefficient of viscous drag forces. The empirical formula was proposed for estimating the residual nutation angle resulted from incorrect installation of passive auto-balancers (nutation dampers) on the spin-stabilized spacecraft, as well as an example of its application for a specific Brazilian satellite (SACI-2) was given. It is shown that improper installation of the auto-balancer (nutation damper) on the lifting body can cause residual nutation angle even in the case of "steady" lifting body. The results can be used in the design of passive auto-balancers (nutation dampers) (pendulum, ball and liquid) for spacecrafts or spin-stabilized artificial satellites of the Earth.
