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.
