Abstract
A mounting apparatus for a rotational drive unit. The rotational drive unit includes a socket portion which receives a truck or carrier. Opposing engagement surfaces of the carrier are separated by a distance greater than the length of the socket. The resulting lost motion connection allows for a range of free movement of the rotational head on the carrier.
