Table 4-10, Measured Torque - Garmin G1000 System Maintenance Manual

4.9.2 Manual Slip Clutch Test Procedure
This test is an alternative to the automated slip clutch test procedure.
This adjustment requires the use of the Garmin servo adjustment fixture,
P/N T10-00110-01. For detailed operating instructions for the fixture, refer to
GSA8X / GSM85(A) Installation Manual, listed in Table 1-3.
It is highly recommended that the following test be performed at temperatures
between 50° F and 120° F.
1. Remove the GSM 86 servo gearbox as per Section 6.12.
2. Place the GSM 86 servo gearbox on the slip-clutch adjustment fixture and secure with the toggle
clamps. Install the fixture cable between the capstan under test and the fixture capstan. Remove the
slack in the cable using the tension adjustment knob. Tighten the two wingnuts on bottom of fixture
while holding the top thumbscrews.
3. Attach a socket to a calibrated torque wrench of appropriate range and place on top of the fixture
capstan. Adjust the wrench support fixture so that it contacts the handle in the appropriate location.
4. Connect a 2 Amp, 24 V, DC power supply to the fixture.
5. Place the solenoid switch to "on" and move the direction switch to the clockwise or counter-
clockwise position. Allow the clutch to rotate at least one revolution in each direction (note: the
capstan itself is fixed.)
6. Observe the torque reading for at least two full revolutions in each direction. Record the minimum
and maximum torque values. When finished, remove the fixture cable, and then remove the servo
gearbox from the fixture.
7. If the minimum and maximum torque values are within the specified range in Table 4-10, the slip
clutch cartridge is acceptable. Reinstall the GSM 86 servo gearbox per Section 6.12.
8. If the minimum and maximum torque values are not within the specified range in Table 4-10, the slip
clutch cartridge must be replaced.
