J. BOLT TORQUE INFORMATION
Torque, in foot-pounds, is determined by the length of the wrench handle (in feet) multiplied
by the weight (or force in pounds) applied at the end of the handle. For example, if the
wrench is one foot long and fi ve pounds of force is applied at the end of the handle, the
total torque applied would be fi ve foot pounds. A six inch wrench would require ten pounds
of force to obtain fi ve foot pounds of torque.
The only way to actually tighten high strength bolts is with proper lubrication and a torque
wrench. Proper use of the torque wrench is important. To obtain the listed torques, a steady
pull should be exerted to the handle until the desired torque is reached.
The following torque specifi cations apply to the bolts from the vibrator assemblies listed.
Whenever any of these bolts, are installed or replaced, the given torque specifi cations
should be adhered to.
