7) Using the test stand switch marked "CAPSTAN ROTATION", rotate the test stand motor clockwise (CW) and read of the torque indicated on the torque wrench.
8) Repeat this step rotating the motor counterclockwise (CCW).
NOTE : The reading of the required torque corresponds to the continuous rotation torque.
9) Repeat steps 7) and 8) twice.
NOTE : The mean value of the 6 readings determines the actual friction torque reading value.
10) Compare the actual friction torque to the required friction torque - refer to Table 501.
11) If clutch friction torque is out-of-tolerance, perform the following operations
a) Remove torque wrench (7), adapter (6) and locating pin (3).
b) Hand-hold drive capstan (9).
c) Rotate nut (8) clockwise if friction torque is less than the required torque and counterclockwise if the friction torque is greater than the required torque.
d) Repeat steps 4) thru 11).
12) Disconnect the power supply source.
13) Remove torque wrench (7), locating pin (3) and adapter (6).
14) Remove mounting plate (2) from test stand (1).
15) Install mounting plate (2)
