4.7 UNIDRIVE TORQUE REQUIREMENTS
Extensive damage may occur if the proper hardware is
not used and/or proper procedures are not followed
when working with the unidr ive a ssembly. Periodic
inspection of hardware andbolt torque isrecommended
to ensure the integrity of the unidrive.
Torque value and hardware requirements for unidrive
assembly are provided in Figure 4-11.
