Abstract

An adjustable bent housing (10) includes a first tubular body (12) and a second tubular body (14). The second tubular body (14) telescopically extends into the first tubular body (12) and is maintained in relative axial position by a threaded engagement (30 & 22). A locking sleeve (44) is provided to maintain the relative rotational position of the first tubular body (12) and the second tubular body (14). The locking sleeve (44) is non-rotatably coupled with and slidably movable the second tubular body (14) between a locking position and an adjusting position. A locking nut (48) is movable on the external surface (24) of the second tubular body (14) selectively clamps the locking sleeve (44) in the locking position. This adjustable bent housing (10) accommodates larger diameter drive shafts, while allowing adjustment to take place without changing the overall length of the housing.
