The M9 service stand floor plate (TB23351) was installed in the M9 pit yesterday. Prior to installation all 5 threaded inserts were tested using a 1/2"-13 stud tool on an RH pole. The west most hole (shown in red below) had damaged threads and the stud could only be threaded in 2 turns. All other locations (shown in green) had usable threads with 6-8 full turns possible with the stud tool. The plate was installed using RH floor plate bolts (TB23382) at all four locations with viable threads. The bolts were torqued to 30 ft*lbs which on a bench test was shown to fully compress the belleville washer. The standard torque spec for 1/2"-13 stainless bolts (43 ft*lbs) was not used to allow easier disassembly in the future.
