After reinstalling the piston and rod assembly, we checked the gap between the rods with a feeler gauge for between 0.015 and 0.025 of side clearance. For the final assembly, we used a stretch gauge instead of a torque spec. The spec for a 3/8-inch capscrew is 0.0060 to 0.0067 bolt stretch. The tool was installed with the point of the dial indicator on the dimple at the top of the capscrew and the set screw on the bottom. After preloading the dial indicator 0.200 to 0.400 and zeroing the gauge, we slowly tightened the capscrew until we saw 0.0060 on the dial indicator.
