Measurement
Repeat the measurement several times to get a stable value.
The breakaway torque is calculated on the basis of the force (F) measured
in N and the length of the lever arm (L) used at the normal distance from it
in m (N x m = Nm).
Obtained value
The value determined must be between 600 and 800 Nm (442 and
590 ft.lb.).
If the value is greater or smaller than the limit value, the overload clutch
must be inspected, repaired or overhauled in accordance with the BRP-
Powertrain instructions for continued airworthiness.
