We derive the dynamical equations which couple the four-body ([pi][ital NNN]) system to the underlying three-nucleon system. Our treatment can be considered the proper generalization of the Afnan-Blankleider equations for the coupled [ital NN]-[pi][ital NN] system. The resulting connected-kernel equations resemble in structure the Yakubovski[hacek i]-Grassberger-Sandhas equations for the standard four-body problem, but involve 24 chain-labeled components (rather than the usual 18 ones) and, within the scheme where the Hilbert space is truncated to states with at most one pion, allow for a consistent evaluation of reaction amplitudes involving [pi] absorption/production.
