Using the O(5) form of the pseudoparticle solution in gauge theories, we have calculated the eigenspectrum of small oscillations near this solution. It appears that the equation for the small fluctuations involves only O(5) Casimir operators and thus eigenvalues can be found without explicit calculations. The regularization and renormalization problem are discussed in detail.
