Remove the nuts from all hex mounting studs.
Swing the pivot arm to the side of the bracket assembly that is opposite to the damaged stud, and slip the
pivot arm over the studs.
Using a 3/4-inch wrench, remove the damaged hex stud.
Using the 3/4-inch wrench, install the replacement hex stud.
Removal and Replacement of Pivot Arm.
Retain the pivot arm by threading nuts onto the hex studs that pass through the pivot arm.
Remove the retaining ring from the rear of the bracket assembly shaft.
Slide the shaft out of the bracket assembly.

3-16. STARTER MS1 (fig 2-8)
Description. Starter MS1 protects the varidrive of the test stand against overload. It consists of a starter coil,
three overload relays, three heaters, and contacts. Testing of the starter and removal and installation of heater elements
can be accomplished with the starter installed in the test stand. For other repair procedures, the starter must be removed
from the test stand. Starter removal procedures are provided in paragraph 2-21.
Testing of Overload Relays and Coil.
Disconnect the main power source from the test stand.
Disconnect the wire leads from each of the three overload relays, and depress each overload relay reset
Disconnect the wire leads from the starter coil.
Using an ohmmeter set to its lowest range, check for continuity (zero ohm) across each overload relay.
Using the ohmmeter, measure the resistance of the starter coil. The resistance should be approximately 2
Reconnect all wire leads at the end of the test.
