The configuration-space Faddeev equations are solved for Hamiltonians that include the Tucson-Melbourne, Brazil, and Urbana two-pion-exchange three-nucleon force models. Convergence in terms of the number of three-body partial waves is demonstrated. First-order perturbation theory results are shown to be inadequate. All three models produce approximately 1.5 MeV additional binding, which overbinds the triton, when the standard value of the πN form factor cutoff is used.
