Manifold with repairable thread insert assemblies within manifold boreholes

A system comprising:

• a manifold, comprising:
• a first surface configured to seat an implement;
• a second surface spaced apart from the first surface;
• and
• a body extending depth-wise from the first surface to the second surface, wherein the body defines:
• a borehole that extends depth-wise, partially through the body, from the second surface towards the first surface to define a shaft seat within the body, wherein the borehole has an inner bore surface defining an inner boundary shape;
• and
• a body through hole that is coaxially located with the borehole and is radially smaller than the borehole, the body through hole extending to the first surface;
• and
• a repairable thread insert assembly, comprising:
• a shaft inserted in the borehole, the shaft defining:
• first and second end surfaces that are axially spaced apart from each other, wherein the shaft is axially shorter than the borehole, and wherein the second end is located at the shaft seat;
• a threaded through hole extending between the end surfaces;
• and
• an outer surface extending between the end surfaces and defining an outer boundary shape that is complementary to the inner boundary shape of the borehole;
• an elastic ring having an outer surface that, unless compressed, is radially smaller than the borehole;
• an assembly fastener having a head that compresses the elastic ring between the head of the assembly fastener and the first end surface of the shaft such that the outer surface of the ring is pressed against the inner bore surface of the borehole and the shaft is locked within the borehole.
