GENERAL TORQUE INFORMATION.
The following information may be helpful, to assure proper torque on bolts and nuts.
1.
Wet threads and seating area with lubricating oil before fitting nuts.
2.
Screw the bolts in until they are squarely seated, using a socket wrench without handle extension or a box or
ordinary wrench without making use of the leverage.
3.
Pre-load the bolts by holding the handle extension so that both hands are in contact with the wrench. When
using a box or ordinary wrench for pre-loading, the tip of your straight thumb holding the wrench must touch the head of
the bolt.
4.
Tighten the bolts according to the appropriate torquing table, if necessary in stages, in conformity with the
tightening angles specified.
