Figure 4-12. Unidrive Torque Requirements
The figures below show the torque value, size and
grade of the hardware to be used when assembling the
unidrive assembly.
Extensive damage may occur if the proper hardware
and procedures are not followed. Periodic inspection of
hardware and bolt torque is recommended to ensure the
integrity of the unidrive.
