Carrier 69UG15 Unidrive Torque Requirements, Engine & Generator SHOCKMOUNTS/ISOLATORS TOP View

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 4-11.

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 4-11.
