N O T E
There is a 3-inch center-to-center distance
between the bell cup and the 3/8-inch socket
square on the wrench. This distance must be
factored in when reading the proper torque on
the wrench.
Example: A desired true torque is desired
using a 9-inch effective length torque
wrench. Wrench offset is 3-inches.
L = 9-inches
TT = 50 lbs•in
E = 3-inches
DR = is dial reading.
DR = 50 (9) DR = 37.5 lbs•in
