FIELD MAINTENANCE

TORQUE LIMITS

GENERAL

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.

TORQUE TABLES

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).

NOTE

Perform Step 2 for standard screws only. To determine if screw is standard or metric,

check capscrew head and refer to Figure 2.
