A system for coupling excavation equipment components is provided. The system includes a retainer (38,138) pin having first and second detents (38,39) which are extendable axially from a surface of the retainer pin, in response to rotation of a valve (66) seated at least partially within a cylindrical bore (62) which extends at least partially through the retainer pin. In accordance with the particular embodiment, the valve (66) includes at least one slotted portion (70) configured to receive the detents (38,39) at least partially therein, when the detents are in a retracted position.
