Abstract:

A well drilling head housing comprises a sidewall structure, a ram and selective displacement means. The sidewall structure defines a central bore configured for having a bearing assembly removably seated therein. The ram is slideably mounted on the side wall structure and is disposed within a passage extending through the sidewall structure. The selective displacement means is coupled between the ram and the sidewall structure. The selective displacement means, is configured for moving the ram to an engaged position in which the ram is engaged with the bearing assembly for securing the bearing assembly in a seated position within the central bore and a disengaged position in which the ram is disengaged from the bearing assembly thereby allowing the bearing assembly to be removed from within the central bore.
