A new single Faddeev equation for the inclusion of a three-nucleon force (3NF) into the three-nucleon (3N) continuum and a new partial wave decomposition of a 3NF is presented. This allows for the first time in momentum space calculations the inclusion of a 3NF in higher angular momenta. We present converged calculations including a 3NF up to jmax=6 for the three-nucleon bound state and jmax=3 in the 3N continuum, where j is the total nucleon-nucleon angular momentum. Several 3N Hamiltonians are generated based on modern nucleon-nucleon (NN) forces and properly adjusted 3NFs, which give the correct triton binding energy. They are used to analyze recent measurements of spin transfer coefficients in elastic nucleon-deuteron scattering. We show that Ky'y scales with the triton binding energy, whereas Kyz'z' does not.
