STARTER-GENERATOR INSTALLATION

A. Verify that the battery switch is OFF and that external power is disconnected. Disconnect
batteries.
B. Install new "0" ring on starter-generator drive shaft. Lubricate "wet-type" splines with engine
oil.
C. Position the starter-generator on the mounting adapter and secure it in place with the quick-
disconnect clamp.
D. Close the clamp hinge over the T-bolt. Check with a mirror to make certain the clamp
groove fully captures both the flange on the quick-disconnect adapter and the flange on the
starter-generator around its entire circumference.
E. When the clamp is properly positioned and the hinge and T-bolt are closed, tighten the T-
bolt nut to a torque of 70 inch pounds. Tap circumference of clamp lightly with
plastic/rudder mallet. Re-torque T-bolt nut to 70 inch pounds and repeat until you achieve
70 inch pound of torque without nut moving.
F. Connect the electrical leads to the starter-generator as previously marked.
F. Secure the upper aft engine cowling and connect the batteries. Run the engine at idle speed for
at least two minutes. Shut down the engine and recheck the quick-disconnect clamp for
proper torque.
