Slip-Clutch Adjustment
In order to install the GSM 85(A), the slip-clutch must first be set to the prescribed slip point. This is
accomplished by using the test fixture shown in Figure 2-1. A motor attached below the fixture turns the
capstan in both clockwise and counter-clockwise directions. The capstan is connected using a chain or
cable to an idler pulley. A torque wrench attaches to the pulley. The wrench's travel is limited by means
of a supporting bracket, which prevents the capstan from being able to rotate freely. Any torque that is
applied to the capstan is transferred through the idler pulley and is shown in in-lbs on the torque wrench.
The technician can set the slip-clutch to the proper value by setting the clutch adjustment nut while
observing the torque wrench. See Section 3.3 for the slip-clutch setting procedure.
