When the yoke and plate assembly screw is tightened, there should be a maximum of 1/64-inch play in the assembly. (To tighten the screw use a torque of 20 to 25 lb-in.) At this point, a mandatory inspection is performed by a quality assurance inspector. All of your work stops until the mandatory inspection is performed and the assembly has been found acceptable.
