GENERAL.

This section provides general torque limits for screws used on the M101 and Ml 16 Series trailer. Special torque limits

are indicated in the maintenance procedures for applicable components. The general torque limits given in this

appendix 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 more turn.

TORQUE LIMITS.

Table H-1 lists dry torque limits. Dry torque limits are used on screws that do not have lubricants applied to threads.

Table H-2 lists wet torque limits. Wet torque limits are used on screws that have high-pressure lubricants applied to

threads.

HOW TO USE TORQUE TABLE.

Measure the diameter of the screw to be

installed.

Count the number of threads per inch or use a

pitch gage.

Under the heading SIZE, look down the left-

hand column until the diameter of screw to be

installed is found (there will usually be two lines

beginning with the same size).

In the second column under SIZE, find the

number of threads per inch that matches the

number of threads counted in step 2.
