This work package provides general torque limits for screws used on the dump body. Special torque limits are
indicated in the maintenance procedures for applicable components. The general torque limits in this WP shall be
used when specific torque limits are not indicated in the maintenance procedure. These general torque limits
cannot be applied to screws that retain rubber components. The rubber components will be damaged before the
correct torque limit is reached. If a special torque limit is not given in the maintenance instructions, tighten the
screw or nut until it touches the metal bracket, then tighten it one complete revolution.
Figure 4 lists dry torque limits. Dry torque limits are used on screws that do not have lubricants applied to the
threads. Figure 5 lists wet torque limits. Wet torque limits are used on screws that have high-pressure lubricants
applied to the threads. For metric fasteners dry torque, refer to Figure 6, and for metric fasteners wet torque, refer
to Figure 7 for torque limit requirements.
HOW TO USE TORQUE LIMITS
Measure the diameter of the screw you are installing (Figure 1).

Perform Step 2 for standard screws only. To determine if screw is standard or metric,
check capscrew head and refer to Figure 2.
