Abstract
A socket assembly for rotating a nut, the nut having an annular body with a radially inner edge defining a torque transferring surface, the socket assembly has: an intermediate socket extending axially relative to a central axis between a proximal end and a distal end, the proximal end of the intermediate socket engageable by a tool for rotating the intermediate socket about the central axis; and socket segments detachably connected to the intermediate socket in a circumferential array about the central axis, a socket segment of the socket segments having a nut-engaging end projecting radially outwardly relative to the distal end of the intermediate socket and engageable with the torque transferring surface of the nut to transfer a torque from the intermediate socket to the nut via the socket segments.

A socket assembly for rotating a nut, the nut having an annular body with a radially inner edge defining a torque transferring surface, the socket assembly comprising:
- an intermediate socket extending axially relative to a central axis between a proximal end and a distal end, the proximal end of the intermediate socket engageable by a tool for rotating the intermediate socket about the central axis;
- and
- socket segments detachably connected to the intermediate socket in a circumferential array about the central axis, a socket segment of the socket segments having a web and a nut-engaging end secured to the web and projecting radially outwardly from the web, the nut-engaging end projecting radially outwardly relative to the distal end of the intermediate socket and engageable with the torque transferring surface of the nut to transfer a torque from the intermediate socket to the nut via the socket segments, the web of the socket segment disposed radially inwardly of the intermediate socket.
A method of assembling a side housing of a rotary internal combustion engine, the side housing having a side plate securable to a side wall via a nut, the nut being recessed radially-outwardly from a periphery of a central hole of the side plate, the method comprising:
- inserting nut-engaging ends of socket segments through the central hole and moving the nut-engaging ends radially outwardly relative to a central axis of the nut until the nut-engaging ends engage the nut;
- and
- threadingly engaging the nut to a central threaded connection of the side plate by rotating an intermediate socket engaged to the socket segments to induce rotation of the nut about the central axis.
A kit comprising:
- a rotary internal combustion engine having a side housing including a side wall securable to a side plate via a nut, the nut recessed radially-outwardly from a central aperture of the side plate;
- and
- a socket for engaging the nut to secure the side plate to the side wall, the socket having:
- socket segments circumferentially distributed around a central axis and insertable within the central aperture of the side plate, the socket segments having nut-engaging ends to engage the nut;
- and
- means for transferring a torque from a tool to the socket segments to rotate the nut about the central axis.
