[1]
Nominal over off center gear preload.
[2]
Specified torque, because the length of the tool required to torque the nut will affect the reading on the torque wrench. The torque reading should
be computed using the length of the torque wrench and the nominal specified torque:
Formula
(Length of Torque Wrench x Specification)/(Length of Torque Wrench + Special tool length) = Torque (using tool).
Example:
Length of Torque Wrench = 13 in.
Length of Special Tool = 5.5 in.
Specification = 98 Nm (72 ft. lbs.)
^
13 x 98 (72)/(13 + 5.5) = 67 Nm (50 ft. lbs.)
Result
The specified torque reading should be 67 Nm (50 ft. lbs.).
