the Carbon Brushes (105) are worn down and need to be replaced. See Figure 5 below.

the Left Tail Cover (96) and the four screws that attach the Right Tail Cover (91). See

is connected to. Disconnect the Carbon Brush connector and insert the new brushes
by bushing them into the Brush House (104). After both Carbon Brushes (105) are
inserted, attach the Carbon Brush connector, the Left Tail Cover (96) and the Right Tail
Cover (91). See Figure 5 below.
