Thread timing for a rotary shouldered connection

A method for establishing an advance timing correction on;

• a ring gage having an outer cylindrical surface and an inner threaded cylindrical surface, and a plug gage having an outer cylindrical surface and a threaded protruding member;
• said gages for use when manufacturing a rotary connection between a first tool having a male timed rotary connection and a second tool having a female timed rotary connection, comprising the steps of:
• securing said ring gage in a rotary indexing head, said indexing head disposed on a flat surface, said ring gage being positioned such that said outer cylindrical surface of said ring gage is parallel to said flat surface;
• locating a center height of said ring gage, said center height indicative of the distance from said flat surface to the center of said ring gage;
• scribing a first line on said outer cylindrical surface of said ring gage at said center height;
• rotating said ring gage by an angular distance indicative of full torque make-up for said rotary connection;
• scribing a second line on said outer cylindrical surface of said ring gage at said center height;
• rotatively connecting said plug gage to said ring gage until tightened by a preselect amount;
• and
• scribing a third line on said outer cylindrical surface of said plug gage corresponding to said first line on said ring gage.

A method for inspecting a male timed rotary connection of a first tool and female timed rotary connection of a second tool, comprising the steps of:

• rotatively connecting a ring gage to said male timed rotary connection of said first tool, said ring gage has an outer surface with first and second scribe lines thereon, said second scribe line being an angular distance away from said first scribe line, said angular distance being indicative of full torque make-up of a rotary connection comprising said male timed rotary connection of said first tool and said female timed rotary connection of said second tool, said first tool has a first reference line thereon corresponding to said second scribe line on said ring gage;
• measuring a first angular distance between said first reference line on said first tool and said second scribe line of said ring gage, said first angular distance to be within a first specified angular tolerance;
• rotatively connecting a plug gage to said female timed rotary connection of said second tool, said plug gage has an outer surface with a third scribe line thereon, said third scribe line corresponding to said first scribe line on said ring gage and being indicative of a preselected tightness of said rotary connection, said second tool has a second reference line thereon corresponding to said third scribe line on said plug gage;
• and
• measuring a second angular distance between said second reference line on said second tool and said third scribe line of said plug gage, said second angular distance to be within a second specified angular tolerance.

A method of reworking a timed rotary connection of a tool having a sensor disposed thereon;

• comprising the steps of:
• (1) machining said timed rotary connection to a preselected distance above a specified standoff;
• (2) scribing a first line on said tool, said first line being in angular alignment with said sensor;
• (3) rotatively connecting a gage to said timed rotary connection of said tool until tightened by a preselected amount, said gage having at least one second line scribed thereon;
• (4) measuring a angular distance between said first line on said tool and said second line on said gage, said angular distance to be within a specified angular tolerance;
• and
• (5) facing off the shoulder of said tool to said specified standoff.
