* Slowly and carefully apply steadily increasing force to the torque wrench until the fas-
tener starts to move. It is important the torque applied be just enough to barely move
the fastener. If the fastener is rotated more than just a few degrees, the torque measure-
ment will be higher than the applied torque by a significant percentage.
The third photograph depicts this portion of
the process. The fourth photograph is a
closeup of the socket and cardboard. In this
photograph, the line on the socket has moved
just enough that it is no longer aligned with
the line on the cardboard. This is the point at
which torque application stops and the torque
reading is taken.
The importance of stopping the torque application at this
point is difficult to over-emphasize. Stop torque applica-
tion immediately when the two lines are no longer in
complete alignment with each other.
* Record the obtained torque.
This number will be the one
used in selecting the correct
filter. You may wish to
repeat the above steps sever-
al times to assure you do not
have a "flier" as your data
point.
