Align coupling and shafts within the allowable figures given in Table 1.
Accurate alignment can extend life.
After the coupling and shafts are aligned, connect the shafts by tightening the set screws or the socket bolts.
Tighten them by torque wrench at the torque strengths shown in Table 2.
Leave a small gap between the top of the drive tenons of a hub and the insert for allowable
axial misalignment rating.
