PREVENTIVE MAINTENANCE CHECKS AND SERVICES (PMCS), INCLUDING
LUBRICATION INSTRUCTIONS Continued
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.
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.
To determine the corrected scale or dial reading, use the following formula and refer to the example.
