A system to retain a sleeve within a housing includes a sleeve, a spring loaded retaining pin which can be moved to be fully within the sleeve, a locking pin to hold the retaining pin within the sleeve when the sleeve is being set into or withdrawn from the housing, and an annular recess in the housing to receive the retaining pin when the sleeve is set in the housing, the locking pin is removed and the retaining pin is pushed outward by the spring. The sleeve is retained within the housing when the spring pushes the retaining pin outward so that the retaining pin engages the annular recess in the housing. |
