Abstract
An adjustable housing assembly is provided, which includes a splined housing and an adjusting ring which contain a splined mandrel. The splined mandrel is moveable axially within the housing assembly when disengaged from upstream and downstream portions of a drill string to disengage the mandrel from the splined housing. The splined mandrel is rotatable with the adjusting ring to alter angled interfaces between the components to change the bend angle in the housing.
