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 unidrive assembly. Periodic
inspection of hardware and bolt torque is recommended
to ensure the integrity of the unidrive.
Torque value and hardware requirements for unidrive
assembly are provided in Figure 4-12.
NOTES
SST is an abbreviation for 300 Series Corrosion
Resistant Steel.
Loctite #242 or an equivalent product should be
used on ALL hardware shown in Figure 4-12.
