USE OF TORQUE WRENCH ADAPTERS AND THE CONVERSION FORMULA.
1)
The torque values given in the text of this manual are the actual values that must be applied to the nut or
screw for proper maintenance.
2)
Some tasks require the use of a torque wrench adapter when the nut or screw cannot be reached with a regular
socket on the end of the torque wrench. When an adapter is used on a torque wrench, definite rules must be
followed or the nut or screw will be over- or under-torqued. The center line of the adapter should be used in
one of two positions:
a)
One position is to have the adapter center line at right angles to the center line of the torque wrench. In
this position, the indicator reading does not have to be calculated and it may be read direct.
b)
The other position is to have the center line of the adapter in line with the center line of the torque
wrench. In this case, the adapter adds to the overall length of the torque wrench and makes the dial or
scale reading less than the actual torque applied to the nut or screw. To prevent overtorquing and damage
to equipment, you must calculate a corrected dial or scale reading.
