  We consider the problem of the ordinary charged fermion mass patterns in the
framework of a version of the 3-3-1 electroweak gauge model, which includes
charged heavy leptons. The masses of the top and the bottom quarks are given at
the tree level. All the other charged fermions get their masses at the one loop
level. The Yukawa coupling strength can be universal. The model is compatible
with a mechanism for neutrino mass generation proposed by other authors.
