We introduce new values of the strength constants (i.e., a, b, c, and
d coefficients) of the Tucson-Melbourne (TM) 2Ο exchange three nucleon
potential. The new values come from contemporary dispersion relation analyses
of meson factory ΟN scattering data. We make variational Monte Carlo
calculations of the triton with the original and updated three-body forces to
study the effects of this update. We remove a short-range -- Ο-range part
of the potential due to the c coefficient and discuss the effect on the
triton binding energy.Comment: 12 pages, to appear in Few-Body System
