  The $SU(2N_{f}) X O(3)$ constituent quark model symmetry of the light diquark
system are used to analyze single pion transitions of S-wave to S-wave and
P-wave to S-wave heavy baryons. We show that the Heavy Quark Symmetry (HQS)
coupling factors are given in terms of the three independent couplings
$g_{\Sigma_Q \Lambda_Q \pi}, f_{\Lambda_{Q1} \Sigma_Q \pi}$ and
$f_{\Lambda^{*}_{Q1} \Sigma_Q \pi}$.
  Light-Front quark model spin wave functions are, then, employed to calculate
these couplings and to predict decay rates of single pion transitions between
charm baryon states.
